Thermocouple Degradation Diagnostic

Thermocouple Degradation Diagnostic acts as a gauge of the general health of the
thermocouple and is indicative of any major changes in the status of the thermocouple or the
thermocouple loop. The transmitter monitors the resistance of the thermocouple loop to
detect drift conditions or wiring condition changes. The transmitter uses a baseline and
threshold Trigger value and reports the suspected status of the thermocouple based off the
difference between these values. This feature is not intended to be a precise measurement of
thermocouple status, but is a general indicator of thermocouple and thermocouple loop health.

Thermocouple diagnostic must be Enabled as well as connected and configured to read a
thermocouple type sensor. Once the diagnostic has been activated, a Baseline Resistance value
is calculated. Then a Trigger threshold must be selected, which can be two, three, or four times
the Baseline resistance, or the default of 5000 ohms. If the thermocouple loop resistance
reaches the Trigger Level, a maintenance alert is generated.

Note

The thermocouple resistance algorithm does not calculate resistance values while the active
calibrator mode is enabled.

Configure T/C Diagnostic with a Field Communicator

From the

HOME

screen, enter the Fast Key sequence.

The Thermocouple Degradation Diagnostic monitors the health of the entire thermocouple
loop, including wiring, terminations, junctions, and the sensor itself. Therefore, it is
imperative that the diagnostic baseline resistance be measured with the sensor fully
installed and wired in the process, and not on the bench.
