The Optris Xi 1M is a short-wavelength infrared camera that offers innovation, affordability, and precision in non-contact thermal imaging of challenging objects. Designed to operate within the short-wavelength infrared range (1M: 0.85 – 1.1 μm), this forward-looking infrared camera is engineered to capture measurement data for precise surface temperature analysis of hot steel, iron, brass, copper, tin, carbon, ceramics, and semiconductors. Addressing the rigorous demands of various industries, the Optris Xi 1M offers wide elevated temperature measurement ranges, exceptional accuracy, and customizable field-of-view configurations.

Many measurement objects made of non-shiny material show high and relatively constant emissivity independent of their surface consistency, at least in long-wave spectral ranges. Nevertheless, many metallic and shiny materials have low emissivity at long infrared wavelengths. The low emissivity of those materials in the long wavelength infrared bandwidth results in varying and unreliable measuring results.

The spectral range of a short wavelength Xi 1M infrared camera matches most metallic material’s highest emissivity, which eases remote temperature measurement. In addition, due to Planck’s radiation law, exponentially more infrared radiation is emitted in the short wavelength range, so linear emissivity issues have less influence on the repeatability of temperature measurement results at short-wavelength. Therefore, contactless temperature measurement of shiny materials at high temperatures should always be as short-wave as possible, considering the higher temperature measuring range. In addition, these infrared cameras boast the capability to autonomously seek thermal hot spots, enhancing their utility and efficiency in various monitoring and inspection tasks. The Xi 1M infrared camera is specially designed and manufactured in Germany for these challenging industrial applications and outperforms long-wavelength infrared cameras in precision, accuracy, and repeatability.

Early fire detection and emergency fire planning can be challenging in outdoor locations such as paper mills, sawmills, biomass power plants, scrap metal and waste recycling plants, and other large facilities where fire risks are prevalent. Fire causes significant financial loss annually due to inadequate early detection systems. Infrared cameras are particularly effective for monitoring extensive areas and providing early fire warnings, which are crucial for executing fire emergency action plans.

In numerous industrial environments, monitoring equipment and detecting early fire signs are crucial, especially in extreme temperature conditions. For example, conveyor systems transporting coal or wood chips are often found in cold climates. The bearings in these systems can overheat, risking conveyor malfunction and elevating the fire hazard. Similarly, the friction in wood chip processes can generate small sparks, potentially igniting fires in wood pulp operations. Furthermore, large, damp piles of decomposing mulch, wood pulp, or other biomass materials can spontaneously combust, posing significant dangers to nearby factories or residential areas.

The Xi 400CM Package meets the critical need for continuous monitoring in industrial outdoor settings. This comprehensive package incorporates all necessary components to effectively monitor equipment and fire hazards, offering early warnings when equipment overheats or when ignition temperatures signal the onset of a fire. The package features an infrared camera, an outdoor enclosure equipped with a fan and heating element, a front window air purge, a high-definition video camera, and a USB Gigabit Server for long-distance video transmission.

By consolidating these elements into a single standardized package, the Xi400 CM Package can be offered at an affordable price, resulting in substantial savings compared to custom installations. Enhanced fire safety is achieved by monitoring more areas from multiple mounting locations. The cost-effective nature of this system supports comprehensive area coverage, providing more effective early fire detection solutions.

Central to the Xi 400CM Package’s detection strategy is the utilization of every pixel in the high-resolution 382 x 288 infrared camera to identify hot spots. The high-speed processors within the Xi 400 thermal imager continuously scan the field of view for hot spots that exceed user-defined temperature thresholds. The Xi 400 infrared camera includes a process interface port capable of sending alarm signals (0/4-20 analog output) to external control devices or sprinkler systems. Additional process interface modules can be incorporated to set fire alarm temperatures in various locations within the camera’s field of view, enhancing the system’s ability to detect and respond to potential fire hazards.

The system also supports transmitting high-resolution thermal and video images to a control room PC equipped with PIX Connect Software. This software can be configured to display multiple images from various mounting locations, providing real-time thermal video reviews to identify false positives, such as excavator exhaust pipes or solar reflections on shiny metal surfaces. This feature is crucial in preventing unnecessary activation of fire control systems or emergency evacuations.
Engineered and manufactured in Germany, the Xi 400CM Package offers a comprehensive and affordable early fire detection solution. Engineers worldwide are available to assist with installation questions, ensuring that the system is effectively implemented and operational in various industrial settings.

The INSPECTA FFT-HA3 is a miniature industrial pressure transmitter encapsulated in a sealed acid and dust-proof capsule. The characteristic is selected to be most sensitive at the tube leak frequencies. Due to the harsh environmental conditions including high ambient temperatures this sensors has a  limited life. The sensitivity drops off after a period of five years at which stage the sensor capsule can be changed by the station C&I department

The PI 640i infrared microscope kit is ideal for engineers who need accurate temperature data on small electronic devices or Micro-Electro-Mechanical Systems (MEMS). The ability to see thermal variations and make measurements on small targets depends on the detector resolution, and the optics focus the heat energy from the device onto the IR camera’s detector elements. This ensures precise and reliable temperature measurements, essential for detailed thermal analysis of miniature components.

Many engineers find that temperature measurements made with contact thermocouples on small electronic devices do not correlate with measurements made using a properly equipped infrared camera. This discrepancy is common when the target size is small, as the connection with the thermocouple can act as a thermal bridge, conducting heat away from the target. In such cases, measurements with a non-contact infrared camera are more accurate, as they avoid the heat conduction issues associated with contact methods.

As with microscopes that operate in the visible spectrum, choosing the right optic for any application involves a trade-off between the total observable field of view and the smallest target that needs to be observed and measured. The PI 640i microscope objective can detect temperature changes on targets as small as 28 µm within a total field of view of 18.2 mm x 13.8 mm. A high-resolution IR camera with standard wide field of view optics will only deliver accurate measurements of microelectronic targets with the right infrared microscope optics. The PI 640i microscope packages combine a high-resolution infrared camera with German-designed infrared microscope objectives and a precision mounting stage for working distance adjustment, ensuring precise thermal measurement and analysis of small targets.

Most IR camera manufacturers will quote a single pixel size or IFOV (Instantaneous Field of View) to promote a camera’s ability to resolve small targets. However, accurately measuring temperature with an infrared camera always requires more than one pixel. Infrared cameras with small detector pitch or pixel element size can require as many as 7 x 7 pixels to deliver a temperature measurement within the camera’s accuracy specification. The MFOV (Measurement Field of View) specification is crucial for obtaining correct temperature measurements, as it accounts for the necessary number of pixels to ensure accurate readings.

In addition to low thermal noise, the optimal pixel pitch size of 17 µm for long-wavelength infrared radiation allows a small Measurement Field of View (MFOV) of just 3 x 3 pixels, unlike other infrared cameras with smaller pixels. The superior quality and larger size of the optics also guarantee high image quality, minimising image distortion and ensuring uniform attenuation across the entire image. A wide variety of interchangeable lens optics are available to properly frame and maximise pixel count on the target to be measured. The infrared camera supports a frame rate of 32 Hz in standard mode or 125 Hz in high-speed subframe mode, allowing for the monitoring of fast manufacturing processes.

The PI 640i works with Optris PIX Connect software, available as a free download with free updates. The PIX Connect package includes tools for locating hot and cold spots, histograms, temperature profiling, image subtraction, and other thermal image processing features. For researchers and process engineers, the PC-based PIX Connect platform offers powerful thermal image processing capabilities, enabling users to extract and document fully calibrated temperature measurements from any pixel in the scene.

Time-versus-temperature data can be extracted from live thermal video feeds and recorded thermal video files containing stored temperature data. Engineers can utilise the data collection capabilities to extract the highest, lowest, and average temperatures from areas of any size or shape, along with complex alarm signals. Additionally, the system supports replaying stored thermal video frame by frame, allowing engineers to capture and store radiometric images and trigger snapshots during temperature changes.

Many engineers will take data on several locations on electric devices over a long period using the Temperature/Time feature, which logs data at user-specified intervals and stores it in .csv files. Some engineers prefer capturing the full image and use calibrated sequence files or calibrated .tiff images, which can be recorded at user-specified intervals. The Snapshot sequence storage routine also supports CSV file storage of the complete temperature matrix at user-specified intervals, providing comprehensive data for analysis.

The Series PD-39 X does not measure the differential pressure directly – instead, it uses two absolute pressure sensors to take the measurement indirectly. As well as reducing costs, this differential pressure transmitter is also more robust in relation to unbalanced (one-sided) overloading. The differential pressure range should be at least 5% of the standard pressure range. Each pressure side has two pressure connections, so the

Pressure measurements can be displayed and recorded on PC or Laptop with help of the software ControlCenterSeries30 (CCS30) and a seriel interface cable. Export of recordings to usual file formats possible. Up to 128 devices can be connected together into a KELLER Bus-system.

The Series PD-39 X does not measure the differential pressure directly - instead, it uses two absolute pressure sensors to take the measurement indirectly. As well as reducing costs, this differential pressure transmitter is also more robust in relation to unbalanced (one-sided) overloading. The differential pressure range should be at least 5% of the standard pressure range. Each pressure side has two pressure connections, so the PD-39 X is easy to use in pressure lines

So that the differential pressure can also be measured exactly if the standard pressure range/ differential pressure ratio is high, this series also features the tried-and-tested microprocessorbased technology that is used in Series 30 X. All reproducible pressure sensor errors (i.e. nonlinearities and temperature dependencies) are entirely eliminated thanks to mathematical error compensation. The sensor signals are measured with a 16-bit A/D converter, so the individual standard pressure ranges can be measured to an accuracy of 0,05%FS throughout the entire pressure and temperature range.

Digital Interface

The transmitters have a bus-compatible two-wire RS485 half-duplex interface which is modelled on the ”MODBUS RTU”. KELLER offers interface converters to RS232 or USB for use here. The READ30/PROG30 program and the protocol are freely available. The interface offers these capabilities:

- Readout of pressure and temperature values for both sensors. This allows readout of the diffe- rential pressure as well as the two standard pressure ranges.

- Calibration of zero points and amplification.

- Scaling of the analog output to different pressure ranges or units.

- Configuration settings such as measurement rate, low-pass (LP) filter, bus address, etc.

- Readout of information such as serial number, compensated pressure and temperature ranges, etc.

Analog Output

The analog output is freely scalable via the interface. For flow measurements, the root of the differential pressure can also be outputted. The calculated value can be outputted via an analog interface (0…10 V or 4…20 mA).

The Series 41 X combines the ceramic measurement cell for low pressure ranges with the µP electronics of the digital Series 30 transmitter. The pressure values from the signals of the pressure and temperature sensors are determined by polynomial compensation (see reverse). The values can be displayed and stored on a PC via an RS485 interface and programming can also be carried out.

The transmitters are calibrated to the base range. The PROG30 software permits programming of the analog output signal in each section of the range within the base range (e.g. range 100 mbar. Output 4…20 mA for 20…60 mbar).

With KELLER RS converters K-100 Series, up to 128 transmitters can be hooked together into a bus system and read by means of a PC or laptop. READ30 software allows the current pressure of each transmitter to be read or the pressure activity of several transmitters to be recorded or stored whilst “on line”.

The transmitters are supplied in absolute or gauge versions, with current or voltage output.

The sensing component is a micro-machined silicon pressure chip of high sensitivity. An independent temperature sensor is integrated on the surface of the silicon chip

Series 22 DT was developed and homologated specially for use in so-called "bivalent" vehicles fitted with engines for combined natural gas/gasoline operation. The unconventional design with a small mass swept by the flow results in a fast response with temperature changes, the temperature being measured by an NTC or PT sensor located directly behind the stainless steel separating diaphragm. The same diaphragm transmits pressure via a capillary to a stress-free mounted silicon measuring cell.

The signal processing for pressure and temperature is carried out by an electronic module connected to the sensors by flexible conductors. Mounted to the back of the electronic module, which is directly connected to the 6-pole plug connector are the EMC protection components. A special feature is the immunity from interference from electromagnetic fields up to 200 V/m.

Series 22 offers a reliable cost effective solution for customers requiring medium to high quantities, of mass produced transmitters. Utilising the KELLER automatic brazing lines, this new technology allows crevice-free construction of the pressure port with no internal seals or O-rings, making possible high volumes at low cost.

In the brass 22 M, a steel insert and a nickel diaphragm are brazed into a brass housing. In the steel 22 S, all parts are stainless steel (AISI 316 L). The glass feed-through header and silicon pressure sensor are welded to the steel insert underneath the oil filling.

The electronic circuit is fitted to the Packard plug. EMC-protection-components are mounted on the plug side, the amplifier on the sensor side. A flexible printed circuit “TAB” connects the sensor with the electronics. The transmitters are designed to have exceptionally good EMC ratings and operate over a wide temperature band, ideal for automotive, hydraulic and refrigeration control applications

The DCX-18 ECO is an autonomous, rechargeable battery powered instrument. It features a stainless steel 18 mm in diameter housing designed to record pressure (water depth) and temperature over long periods at a very economical price. Its small size, rechargeable battery, fully welded housing and the relative sensor option are just a few of the many advantages provided by the DCX-18 ECO.

The electronics employ the latest microprocessor technology which give high accuracy and resolution for the pressure and temperature signals. The measured values are mathematically compensated for all linearity and temperature errors of the pressure sensor. The use of a non-volatile memory for data storage ensures high data security.

DCX-18 ECO

The sensor, electronics and the rechargeable battery are housed in a fully welded stainless steel tube for submersible deployment. For data read-out, the DCX-18 ECO must be recovered from the measurement point. The end cap, sealed by two O-Rings, must then be removed to access the serial interface. The DCX-18 ECO works with an absolute pressure sensor. In shallow water depths where the influence of barometric pressure changes should be considered, it is recommended that a second data logger (Baro) is placed at the surface, to record the barometric pressure. The PC then calculates the differential pressure resp. the water depth by subtracting the two measured values.

The electronics employ the latest microprocessor technology, which give high accuracy and resolution for the pressure and temperature signals. The built-in pressure sensor is mathematically compensated for all linearity and temperature errors. The use of a non-volatile memory ensures high data security.

The DCX-25 PVDF works with an absolute pressure sensor. For installation, the data collector is secured by a suspension cable and immersed into the media to be measured and must be recovered for data readout. In shallow water, where the influence of barometric pressure changes should be considered, it is recommended that a second data logger (e.g. DCX-22 Baro) is placed at the surface to record the barometric pressure. The Logger PC software then calculates the water depth by subtracting the two measured values. The housing of the data logger can be opened easily without any tools, thus allowing quick access to the replaceable battery and the interface connector for configuration and data download.

Interface with a PC is accomplished using one of Keller’s converter cables which are available in either RS232 connection (K103A) or USB connection (K104A). The necessary converter drivers are included with converter purchase, along with the Keller Logger software. This intuitive software provides the capability to customize the instrument, as needed, for each installation. Users can configure the DCX-25 PVDF to record at fixed time intervals, using fixed or eventbased start times, in user-selectable measurement methods to ensure that only the most useful and meaningful data is collected and stored.

For applications that do not require highest compatibility with aggressive media, Keller offers the DCX-16, DCX-18, DCX-22 and the DCX-38.

The DCX-38 VG is an autonomous instrument for recording water level with a high resolution and full scale ranges as low as 0,5 mWC / 50 mbar. It features a rugged, gold-plated ceramic diaphragm for outstanding long-term stability and stainless steel housing with user serviceable battery for long service life.

Configuration / Data Retrieval:
For data readout, the serial interface is accessed via the data port located on one end of the cable, enabling on site data retrieval. Using either the K-104A or K-103A converter cable, the DCX-38 VG connects easily to a laptop or PC via USB or serial port. Used in conjunction with Logger 4.X software, the DCX-38 VG is configured and data retrieved either in the lab or the field

LEO 2 is a compact, micro-processor (µP) controlled, highly accurate and versatile pressure measuring instrument with digital indication. The piezoresistive pressure transducer as the heart of the instrument has gone through extensive pressure- and temperature tests. Its characteristics are stored in the instruments internal EEPROM. The µP of the LEO 2 reads the characteristic values and calculates therefrom the pressure to an accuracy of < 0,1 %FS at room temperature.

The pressure is measured twice per second and displayed. The top display indicates the actual pressure, the bottom display shows the Max.- or Min.- pressure since the last RESET.

Also available as intrinsically safe version (LEO 2 Ei).

The LEO 5 combines the notable features of Keller’s successful LEO-Record and LEX 1 digital pressure gauges, featuring an IP66-rated stainless steel enclosure. This robust housing combines contemporary microcontroller-based electronics and capacitive-touch controls, operated through the environmentally-sealed safety glass front panel. The large backlit LCD display ensures readability in any lighting conditions.

Two selectable measurement modes, standard and peak, are included to ensure maximum versatility. In standard mode, high-resolution pressure measurements are taken twice per second. When operating in peak mode, sampling frequency increases to 5 kHz with 16 bit resolution.

The LEO 5 interfaces with a PC via USB connectivity, allowing access to active measurements and recorded data including pressure, peak pressure, temperature, and measurement interval. PC connection also allows device configuration, firmware updates, and recharging of the integral accumulator power supply.

The unique modular design of the LEO 5 makes possible adaptation to customer-specific measuring requirements.

LEO 5 CA offers a user-friendly way to re­present the pressure measurement at the bottom of a tank as the quantity of remaining liquid. At the push of a button, the micro­controller performs the calculations using the information of the tank shape and dimensions and displays the remaining tank content quantity on the clearly legible 5-digit LED display in the desired unit (litres, gallons etc.).

The unit is configured using a PC and the easy-to-use software so that the filling level, which determines the pressure, can be converted into an appropriate filling quantity. First the tank ­shape is selected, then the tank dimensions and the specific gravity of the liquid are entered. It contains the most current tank shapes. The program covers the most common tank shapes, but also enables any shape by entering the parameters into a specified table.

The exclusive use of absolute pressure sensors in the LEO 5 CA system eliminates the use of capillary vented cables with all the problems associated with a gauge pressure measurement. The LEO 5 CA housing integrates an air pressure sensor, ranged between 0,8 bar and 1,2 bar absolute. The sensors to measure the hydrostatic pressure at the bottom of the tank are calibrated from 0,8 to 1,8 bar abs for tanks up to 5 m in height, and 0,8 to 2,3 bar abs for tanks up to 10 m in height. The pressure difference, calculated by the micro-controller, is the relative hydrostatic pressure. The content of a pressurised tank is determined using the difference between the measurements from two absolute pressure sensors located at the top and bottom of the tank

An accuracy of the system of up to 2 mbar (corresponding to a 2 cm water column) is achieved using a computerised calibration and compensation procedure for the pressure sensors.

LEO 5 CA makes it possible to connect various pressure probe transmitter versions (with thread, front-flush with flange, or submersible sensors).

The power supply to the system (8 to 28 V) can be provided externally or internally from an accumulator or a battery. The display is obtained by pressing the button on the front, and the value appears for a configurable duration. The LEO 5 CA has two switch outputs with configurable functionality and threshold values. The device must be supplied externally if the switch outputs are used.
