The SEM110 is an analogue temperature transmitter that accepts Pt100, Differential, Potentiometer and Resisitance sensors. Its range is factory set and can not be changed. 

Calibration is achieved by adjusting potentiometers for the 4 and 20mA output.

ATEX versions of the SEM110 are also available.

This type of transmitter has a virtually instantaneous response time and higher accuracy over the modern digital transmitters.  

So in applications where this is important, these are ideal.  

There is no software in the product, so in applications where long life, high reliability and stability are important, these products are ideal. For example, the nuclear industry.
