PT100 Input
FlexTop 2202 is a 4...20 mA loop-powered transmitter for Pt100 sensors. Either 2-, 3- or 4-wire sensors can be used. For 2-wire sensors an automatic balancing of the sensor cable resistance is possible with shorted sensor cable. The cable resistance can be manually configured as well. Using a PC, the Windows-based Flex-program and a Flex Programmer configuring unit, the following parameters can be configured via the output connectors (2-way communication): TAG no., number of wires, cable resistance, error detection level, measuring range/unit, damping, offset and status indication. The Flex-program has a data logging facility enabling the user to monitor measuring results or calibrate the measuring setup. FlexTop 2202 is embedded in silicone which makes it resistant to humid environments. FlexTop 2202, fitting into the DIN B housing, has a 6 mm centre hole for quick sensor replacement. The spring loaded mounting screws ensure a safe fastening even in vibrating environments.
Flex Top 2211 is a 4...20 mA loop-powered, configurable universal transmitter with galvanic isolation between input and output. The input can be configured for RTD or T/C sensors, resistance, current or voltage signals. Either 2, 3 or 4-wire connection can be selected for the resistance input. The built-in temperature sensor or a remote Pt100 sensor can be used to compensate for "cold junction" (CJC) if thermocouples are connected. Flex Top 2211 is embedded in silicone which makes it resistant to humid environments. The configuration can be established from the dedicated Flex Programmer configuring tool connected to a PC. Flex Top 2211 has a 6 mm centre hole for fast sensor replacement and spring loaded mounting screws which ensure a safe fastening even in vibrating environments. A built-in temperature surveillance system gives alarm if ambient temperature limits are exceeded.
Flex Top 2221 is a 4...20 mA loop-powered, configurable universal transmitter with galvanic isolation between input and output. The input can be configured for RTD or T/C sensors, resistance, current or voltage signals. Either 2-, 3- or 4-wire connection can be selected for the resistance input. The built-in temperature sensor or a remote Pt100 sensor can be used to compensate for "cold junction" (CJC) if thermocouples are connected. The HART® communication feature on-line process calibration and adjustment, transmitter configuration and multiple process control in 2-wire networks. The configuration can be established from a standard HART® configurator or the dedicated Flex Programmer configuring tool connected to a PC. Flex Top 2221 is embedded in silicone which makes it resistant to humid environments. Flex Top 2221 has a 6 mm centre hole for fast sensor replacement and spring loaded mounting screws which ensure a safe fastening even in vibrating environments.
The SEM104P is a temperature transmitter designed to accept a standard platinum resistance sensor (Pt1002 or 3 wire) to BS EN60751, BS1904 or DIN43760 and convert the temperature to industrial (4 to 20) mA. It is housed in a purpose designed DIN standard connecting block enclosure. The transmitters are available in 6 standard factory calibrated ranges, but the transmitter can be user re-ranged to operate over most temperature ranges encountered in both industrial and building management applications. Non standard ranges can be supplied to special order. The enclosure provides trim potentiometer access, allowing fine re-calibration adjustments to be made at both ends of the scale.
The RTD in-head mounted temperature transmitter connects to any standard pt100 resistance sensor and converts the linearised temperature to a (4 to 20) mA signal. The transmitter is a two wire device, and is fully configurable by the user, over a wide temperature range, with the aid of a simple push button. This design incorporates additional configuration menus, allowing the user to push button trim the transmitter output at both zero and span, ideal for trimming out sensor errors. The transmitters advanced circuitry guaranties high stability over the wide operating ambient temperature ranges experienced by head mounted devices. One of the transmitters features is the program LED, which provides visual indication of sensor fault when in normal operation and is also used to guide the operator through the simple menus during configuration.
The SEM206 is our entry level PC programmable temperature transmitter. There are three versions for Pt100, Thermocouple and Thermistor sensors. It will convert the sensor output to a standard industrial (4 to 20) mA transmission signal. PC configuration allows the user to select range, units and burnout direction, without requiring calibration equipment. Configuration is performed quickly using our USB port driven configurator by simply connecting two clips to the SEM206 loop terminals and following the software instructions. Calibration set up may be saved as a file on the PC for later use.
The TT200 Series are our mid range transmitters for RTD, Slidewire, Thermocouple and Resistance sensors. They will convert the sensor input to provide a loop powered 4/20mA output signal. ATEX version are also available The TT200 Series have a calibration feature where the output can be matched to the sensor on the input. It can be matched at zero, or both zero and span ends of the range being measured. It is also possible to measure linear resistance up to 10K Ohms and slidewire sensors up to 100K Ohms. The software allows a user linearisation function to be downloaded into the product. This allows the user to adapt the output to suit a non linear tank for example.
The SEM210 is a universal programmable temperature transmitter which accepts most commonly used Pt100, thermocouple, mV and slide-wire sensors and generates an industry standard (4 to 20) mA transmission signal. This type of product is useful if you use a number of different sensors; you only need to hold one product in stock. The output range and other operating parameters are easily programmed using our free software and USB powered configurator. Isolation is a standard feature to overcome any potential ground loop effects and a sensor referencing facility enables the transmitter to be calibrated to a particular sensor.
Complete with HART Protocol, the SEM310 universal temperature transmitter accepts Pt100, thermocouple, mV and slidewire sensors and can be integrated into systems where the HART protocol is required. The HART communication protocol allows the user to quickly and easily download information or interrogate the device. It is small in size yet has a performance superior to other larger and more expensive transmitters. A sensor referencing facility enables the transmitter to be accurately matched to a particular sensor.
