TX12 rtd amplifier digital adjust zero and span
We used these rtd amplifiers periodically to integrate into systems for resale. I find them superior because we can adjust the zero and span over a wide range of temperatures for various system needs with a relatively simple setting procedure - unlike other types which have a very narrow adjustment band. We use a simple fixed resistance reference set and get accuracy better than +-.25 deg C accuracy with our thin film rtds.

Fast support and shipping!
Omega got me out of a jam with this transmitter. It worked great. Easy to program
