where T is in degrees Celsius. The measured
resistance should be within the expected value by ±
5%.
Moisture intrusion behind the sensor electrode seal
can be detected with the sensor removed from the
process. Thoroughly dry and tested the sensor using
the following procedure:
1. Check the conductance between the yellow
Temperature Sensor lead and each of the other
sensor leads (i.e., green, red, white, black, and heavy
green leads). The reading must be less than 0.05 nS.
2. Check the conductance between the green Drive
lead and each of the other sensor leads (i.e., black,
white, red, and heavy green leads). The reading must
be less than 0.05 nS.
3. Check the conductance between the heavy green
lead (Shield) and each of the other sensor leads (i.e.,
blue, yellow, black, green, red, and white leads). The
reading must be less than 0.05 nS.
Transmitter Electronic Test
The TB82EC FF Transmitter can be electronically tested without requiring the use of a sensor. To perform this type
of test, use the following procedure:
1) Disconnect the sensor from the transmitter.
2) Set the transmitter temperature compensation (TC.TYPE) to MANUAL.
3) Connect the transmitter to a resistance decade box as shown in the figure below.
