Optris Xi400CM

sku Product SKU:  OPT-Xi400CM

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.

OPT- PI-640i

sku Product SKU:  PI 640i Microscope optics

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.

Inspecta III

sku Product SKU:  INSPECTA-III

Locally designed and engineered, based on over 35 years of boiler steam tube leak detection experience in South Africa, Australia and Europe, the Inspecta III uses acoustic detection technology to  detect tube leaks less than 2mm in diameter in the large boiler structure.

The first 10 systems, Inspecta-FFT were sold to Eskom Matla & Duvha in 1985.

Major features include:

• Backward compatibility with existing Inspecta field sensor arrays and plant interfaces.
• Providing a new platform using current industry-standard technologies with modern capabilities.
• New sensor array that minimises installation work and modification to the boiler (future).

The Inspecta III is aimed at large thermal boiler installations in the range 200 MW to 900 MW but can also be tailored for smaller facilities. 

Its extensive diagnostic facilities enable tube leaks to be detected at a very early stage (1mm to 2mm) and the leak progression to be followed. This allows maintenance to be planned and scheduled at an appropriate time instead of suffering an unplanned breakdown and its many bad consequences.

The Inspecta III has been designed to evolve from a basic steam leak detection system with new modern features to an advanced expert system. This will provide effective management information to enable plant operators to efficiently plan and implement required shutdowns and necessary repairs.

The system implements various utility and power station Distributed Control System(DCS) interfacing requirements. These range from 4 to 20 mA to industry standard protocols, such as Modbus and Ethernet.

The figure below shows the Inspecta III system configuration. Built using standard 19”rack technology, the system can either be fitted into a standard 19” rack or used as a desktop version.

Sensor Network

The acoustic sensor network is fitted to particular points on the boiler. These are selected to ensure adequate boiler coverage.

The Inspecta III system utilises sophisticated sensors specifically designed for this application. Sensors can also be fitted with automatic air purging systems to reduce routine maintenance to clear acoustic waveguides of boiler fly ash.

Connection to the sensor network is via a cable network connection.

Inspecta III Server

The sensors connect to a central computer, which captures, analyses and displays the received data and communicates decisions based on the information captured by the sensor network.

The industry standard server runs a variation of the Linux Operating System and connects to the advanced sensor network via the industry standard Ethernet protocol.

Captured data is stored in an SQL and JDBC relational database, processed and conclusions appropriately displayed to the operator.

Connection to Power Station Information System

Connection into the facility or power station information system is either via a separate Ethernet connection or, in the case of an existing DCS, via a standard  industry interface such as Modbus.

This allows the Inspecta III to interface to both modern and older existing utilities as necessary.

Backward Compatibility

Realising that many existing installations will want to upgrade to the new Inspecta III Server and take advantage of the many new features, without incurring unnecessary costs, the new system has been specifically designed to interface with an existing Inspecta sensor network.

By means of an Inspecta Plant Interface Unit (PIU), signals from existing sensor networks are converted to Ethernet and connected to the Inspecta III Server.

Advanced diagnostics that are built into the PIU allow effective remote fault location and diagnosis.
 

Analog Sensor Network

The sensor network consists of transducers mounted at selected points on the boiler structure. Acoustic sensors are typically mounted on boiler inspection doors for convenience. 

	Wired Acoustic Sensor (HA3 Audio sensor) This is the existing legacy product installed at existing Inspecta system sites.
	Pipe Set The PVC pipeset is bolted to a customer supplied stub pipe which terminates approx.. 1m away from the boiler side wall. The PVC pipeset is mounted to the steel flange with airtight gasket supplied by Instrotech. The HA3 audio sensor is attached to the PVC pipeset with a QUICK Release coupling to facilitate easy maintenance and cleaning of soot / fly ash from the Acoustic wave guide pipe.  Positioning of the stub pipes is determined between the supplier and operating & maintenance staff of the customer.
	Automatic Purge System (APS) The APS keeps the Inspecta sensor pipe sets sufficiently clear of fly ash such that the performance of the Inspecta steam leak detection system is continually effective without requiring routine pipe cleaning maintenance. It operates autonomously and reliably once setup, requiring minimum routine maintenance. The system has built-in diagnostics and communicates  any detected faults to the control room.

Inspecta Automatic Purge System

sku Product SKU:  INSPECTA-APS

A fully automatic purging system that is easily retrofitted to existing Inspecta installations.

The installation of this system will eliminate the requirement for routine manual purging of the pipe-sets and maintain the leak detection system at peak performance without manual intervention. Inspecta ASLD systems are installed in most of the ESKOM power stations. Using acoustic detection technology, these systems can detect tube leaks less than 2mm in diameter in the large boiler structure. However, as the coal used by ESKOM is very high in ash content, there is a considerable amount of fly ash remaining after combustion. This fly ash swirls inside the boiler and quickly blocks the ‘listening’ pipe-sets that contain the sensitive leak-detection microphones. Unless the systems are frequently manually or automatically cleaned their ability to detect the leaks early, is significantly degraded.

Optris BR 400

sku Product SKU:  OPT-BR-400

Knowing the exact value of the radiation temperature is essential for the calibration process. It can be measured by either using a contact thermometer (in combination with the determination of the emissivity) or a transfer standard infrared thermometer. This value can then be used to determine the device constant for an initial calibration of the infrared sensors. In order to conduct a post-calibration by customers or local calibration facilities, the calibration temperature should be near the temperatures which occur at the respective applications.

Optris makes use of a transfer standard radiation thermometer CTlaser-PTB (see figure) to measure the radiation temperature of a reference source. The CTlaser- PTB is based on the IR thermometer optris CTlaser. The CTlaser-PTB needs to be traceable to the international temperature scale from 1990 (ITS-90). Thus, it is calibrated by the PTB (German national metrology institute) on a regular basis. ITS-90 is a very good approximation of thermodynamic temperature. It is based on 17 well-reproducible fixed values such as melting points of highly pure metals. Within the framework of ITS-90 the CTlaser-PTB is compared to national temperature standards from the PTB. This comparison within a closed chain of comparative measurements with a known uncertainty in measurement takes place on a regular basis.

Based on the CTlaser-PTB, Optris produces the CTlaser- DCI as a high-precision reference IR thermometer for its customers. The DCI units are produced with pre-selected components supporting high stability of measurement. In combination with a dedicated calibration at several calibration points the CTlaser-DCI achieves a higher accuracy than units from series production.

The optics of an IR thermometer is described by the distance-to-spot-ratio (D:S). Depending on the quality of the optics a certain amount of radiation is also received from sources outside the specified measurement spot. The maximum value here equals the radiation emitted by a hemispheric radiant source. The respective signal change in correlation with a resize of the radiation source is described by the Size-of-source effect (SSE).

As a result of this correlation all manufacturers of IR thermometers use accurately defined geometries for the calibration of their units; meaning depending on the aperture of the radiation source (A) a distance (a) between the IR thermometer and the reference source is defined. Thus, the value specified in datasheets and technical documentation as a measurement field is, in general, a certain defined percentage of this radiation maximum – values of 90 % or 95 % are common.
