This ultrasonic level transmitter is intrinsically safe (IS) and CSA rated for Class I Division 1 hazardous areas in the US and Canada. It has a maximum range of 25 feet (7.62 meters) and is typically used for tank level measurement but can also be used for other hazardous area applications such as measuring the roll diameter on coating machinery. The transmitter sensing element is chemically resistant and the electrical connection is a two-wire loop-powered 4-20 mA output. The SafeSonic 25-L is pre-calibrated from 1 and 25 feet but can be user-calibrated to other ranges using optional accessories.
The level monitor model NSV has decisive advantages, especially with bulk goods with low bulk densitiy. Vibrations are induced in a stainless steel fork by a piezoelectric crystal. If the medium comes into contact with the vibrating fork, this vibration is damped.This damping is detected in a pluggable evaluation module and transformed into a potential-free limit contact. In addition to the standard version NSV-8200, the devices can also be provided for vertical installation with an extended neck pipe (NSV-8201). The maximum length of the neck pipe is 3000 mm. The plug-in evaluation module can be changed easily so that the devices are really easy to maintain. Operation can be set for maximum or minimum security by means of a selector switch (A and B). The respective switching status of the relay is indicated by a LED.
The pressure transmitters of the 7LD series use the chip-in-oil technology developed by KELLER, uniting a pressure measuring cell, digital temperature compensation and signal processing in a compact housing made of stainless steel or Hastelloy. The transmitters are extremely resistant to environmental influences and delivery highly accurate measurement results as a digital output signal. The I2C interface and the low supply voltages make it easy to integrate in microcontroller-based systems. The extremely low power consumption is ideal for battery-operated devices. The D line is perfect for IoT solutions.
The Kobold Differential Pressure Transmitter model PAD is a micro processor-based high performance transmitter, which has flexible pressure calibration and output, automatic compensation of ambient temperature and process variable, configuration of various parameters, communication with HART ® protocol. The application is very various, as measuring pressure, flow and level by application method. All data of sensor is to be input, modified and stored in EEPROM. As an option the Kobold Pressure Transmitter is also available as a flow meter. This flowmeter model PAD-F has added the totalizing function in the PAD transmitter. So it is available to check the flow rate and totalizing flow. It measures the flow rate by using differential pressure without compensation of temperature and static pressure. The shape of the PAD-F is the same as the standard device and it is only the terminal block which is different since there are two more terminals for the read-out of the pulse output.
The KOBOLD Pressure Transmitter model PAS is a micro processor-based high performance transmitter, which has a flexible pressure calibration and a flexible output signal. It has an automatic compensation of ambient temperature and process variables. A communication with the instrument and a configuration of various parameters is possible via the HART ® protocol. All data of sensor is to be input, modified and stored in an EEPROM.
The new KOBOLD type DUK flow meters are used for the measurement, monitoring, metering and dosing of low viscosity fluids. The devices work on the principle of the difference in running times. This is based on the fact that ultrasonic waves in a medium are influenced by the speed of flow. Two sensors mounted opposite one another in the pipeline function simultaneously as transmitter and receiver of ultrasound signals. If there is no flow, then the running times of both signals are identical. If the medium is flowing, then the running time of the signal against the flow is longer than that with the flow. The running time difference, which is determined by a microprocessor, is proportional to the speed of flow. The devices can be equipped with a switching output, a frequency output or an analogue output. In addition, a compact circuit can be selected that features a digital display, a switching output and an analogue output. The device series is rounded off by an optionally available dosing and meter circuit. The meter circuit indicates the momentary flow rate in the first line of the display and the partial or total quantity in the second line. A dosing circuit controls simple filling tasks and similarly measures flow rates, total amounts and filling amounts. The analogue output and two relay outputs can be used for further processing of the signals
The pressure transmitters Series 26 Y are used in water level measurements that are price-sen - sitive but still require considerable accuracy. Technology Y-series transmitters have an extremely small temperature error. This is achieved by means of digital compensation of an all-analogue signal path. The gain and the zero point of the gain circuit can be influenced by digital/analogue converters. These receive their numerical values from an EEPROM that is addressed depending on the temperature. A mathematical model for TC zero and TC gain with any order can therefore be determined in the calibration process and stored in the transmitter with a resolution of 1,5 K. The accuracy of the end product therefore essentially depends on the amount of testing and the linearity of the measuring cell. With the Series 26 Y, the monocrystalline silicon measuring cell is reliably protected from the measuring medium by a stainless steel diaphragm. The steel diaphragm itself is protected from mechanical influence by a plastic cap, and has outstanding performance features with regard to accuracy and stability due to its large diameter of 17 mm The Y-line transmitters have an extremely small temperature error. This is achieved using an additional circuit containing a temperature sensor that subdivides the temperature range into fields that are 1,5 Kelvin (K) wide. The TK zero and TK compensation values are calculated for each field and programmed into the additional circuit. During operation, these values are fed into the analogue signal path depending on the temperature. Each temperature is the „calibration temperature” for this transmitter. The accuracy thereof is mainly determined by linearity. 120 fields are available, representing a possible temperature range of 180 K. The wider the temperature range, the greater the amount of testing that is needed to minimise the inaccuracy of the mathematical model.
The Series 26 W transmitter utilises the Series 10 piezoresistive capsule, which is housed inside a submersible 316 L stainless steel body as standard. For corrosive applications hastelloy diaphragms and other materials are available as options. Series 26 W vented gauge versions have cable with integral vent tube. These transmitters are fitted with durable PE cable.
This Series is based on the stable, piezoresisitive transducer and a micro-processor electronics with integrated 16 bit A/D converter.

The DCX-16 is an autonomous, battery-powered data collector in a stainless steel housing with a very small diameter of only 16 mm. The housing and the pressure sensor element are completely welded in, so sealing rings are eliminated at this point. In applications where a small probe diameter is an advantage, the logger can record the water level (pressure) and the temperature over long periods. As well as the battery compartment with its double seal, the small-diameter (16 mm) submersible sensor includes electronic circuitry featuring the latest microprocessor technology. It records the pressure and temperature of the medium with high measurement accuracy and resolu-tion, and it uses a mathematical model to correct any linearity or temperature errors made by the pressure sensor. High data reliability is guaranteed thanks to the use of a nonvolatile data memory The various configuration options allow the data logger to be adapted to the measuring point so that only specified events will be detected and stored. Event-controlled recording and loginterval recording can be set independently of one another. In addition, installation data and comments on the measuring point can be stored in the logger. Installation is fast and simple with fixing disks of various sizes which can be fitted as options: these match locking units (caps) from different manufacturers for levels of 1” or more (2” or more with light plummet aperture), so measuring points can be implemented at a fraction of the previous cost. Three versions of the data collector are available: DCX-16 The sensor, electronics and battery are accommodated in one housing. To extract data, the data collector must be removed from the measuring point, and the watertight screw cap that allows access to the read-out plug /interface must be unscrewed. The DCX-16 operates with an absolute pressure sensor. In shallow water, when the influence of air pressure fluctuations has to be taken into account, a second logger (barometric logger, obtainable separately) positioned on the surface of the water must be used to record the air pressure progression. The computer software then calculates the differential pressure or the water level by subtracting the two measured data.
LEO Record is an autonomous battery powered instrument with digital display designed to record pressure and temperature over long periods. The pressure is measured and displayed once per second (shortest interval). The top display indicates the actual pressure, the bottom display shows the record status. All LEO Record versions have two operating keys. The left key is to turn the instrument on, to select the functions and the pressure units. The right key executes the selected function or unit.:
