Temperature Transmitter (Thermocouple) Loop Checks Procedure

Thermocouple / Temperature Transmitter Loop Checks Procedure

  1. Check and verify the DCS configuration for applicable points.

  2. Simulate millivolt equivalent to the 0%, 25%, 50%, 75% and 100% of the transmitter / DCS range, by using “mv” source (simulator) at the thermocouple terminal head.

  3. Verify the corresponding reading in the DCS / integral indicator of transmitter and remote indicator if applicable.

  4. Alarm functions (in DCS) to be checked by simulating / varying the required signals.

  5. Normalize all the connections prior to closing the terminal and confirm ambient temperature at integral indicator of temperature transmitter and at remote indicator if applicable to DCS.
