Old post that i use, hopefully it doesnt matter. I have basically exactly same problem.
Im using 4-20mA PT100 transmitter, measures tempareture 0-50c. In 0c output is 4mA and in 50c output is 20mA, but i need to invert that. And i havent seen any PT100 transmitters with inverted output.
Drive that i use for the motor is Altivar 11, manual: https://stevenengineering.com/tech_support/PDFs/45A11UG.pdf
If i understand correctly drive itself doesnt support inverting input. And i dont understand exacty this bias/gain talking that was earlier that can i do it with that trick?
