Level transmitter calibration!
I'd like to know more about calibration of level transmitters. Do we really need to calibrate these devices?.
Expert’s answer: Level transmitter calibration
Level transmitter calibration can be tricky, but… How about no? It’s true! Don’t touch it! You rarely need to calibrate level transmitters in the field. When the companies build these devices, they use a verification doohickey or calibration whatsit to fake various distances and conditions. This way, they see how the device behaves and if it reads the distances and conditions correctly. Good device!
Story time! Once I had a customer insist that all his field devices needed calibration. I was very good; I didn’t roll my eyes or huff in exasperation as I explained that he didn’t need to do it because the lovely company did it for him. No dice. He wanted calibration. We found him a calibrated electronic measuring tape to compare with the radar in the workshop, he played with that for a while, and everybody went home happy. The end!

Rosemount 3144P temperature transmitter
I have a Rosemount 3144P with a range of 0 to 150 degrees Fahrenheit. I was using a test device to simulate RTD input to the transmitter, where on 0 degrees Fahrenheit I have 4 mA and on 150 I have 20. Do I need to calibrate or adjust the transmitter to read the same temperature as the probe? Is the RTD bad?
