The SEM1801/2XR ‘smart’ transmitter is designed for use with RTD or Slidewire sensors and converts the sensor signal into an industry standard (4 to 20) mA loop powered output. Pt100, 500, 1000, Ni, Cu sensors and Slide wire sensors up to 100 K Ohms can be accommodated. Other sensor characteristics or your own 22 point linearisation characteristic (for slidewire or linear resistance) can be downloaded into the product enabling it to be adapted exactly to your application. The product also has a calibrate function where the output can be aligned to the input signal. The SEM1801/2XR is approved to ATEX and IECEx standards allowing for use in hazardous area applications.
