The TT220X series consist of 2 products, one for resistance sensors and one for thermocouple sensors. They are both approved to ATEX and IECEx standards allowing for use in hazardous area applications. The TT200X series are designed for use with RTD / Slidewire, or thermocouple sensors. Other sensor characteristics or your own 22 point linearisation characteristic (for slidewire, linear resistance or mV) can be downloaded into the product enabling you to adapt it exactly to your application.
