Temperature Transmitter Calibration Rosemont 3144 Flashcards
What is the temperature tolerance for temperature transmitter?
+/- 0.2 deg F. for products or crude oil or 0.1 deg. F for chemicals.
How often should a temperature transmitter be verified?
Monthly
Who should be contacted before performing verification and/or calibration?
The control center.
How often does the device need to be out of tolerance before it needs a two point calibration or replaced with a like-kind transmitter?
More than once in six months.
Should a two point calibration take place in the field?
It is difficult to perform in the field so it is recommended to replace the transmitter with a like-kind device.
What is the tolerance that is allowed when calibrating a temperature transmitter?
0.1 deg. F for products and Crude or 0.05 deg. F for chemicals.
What must be done after the transmitter is calibrated?
Compare the analog loop readings.
What is a typical calibration adjustment called?
An Analog Loop Adjustment.
