SEM210X

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.
