Testing the Sensing Element - Step 1 (Figure 6-5)
With the material below the sensor, and the coaxial
cable disconnected at the sensing element, measure the
resistance from the sensing element center connector to
ground connector (or condulet). The ohmmeter should
be set to R x 10000 scale. The reading should be infinite
(open circuit). Readings of less than one meg-ohm indicate
excessive electrical leakage, probably due to product
leakage or condensation in the packing seal or condulet.
Contact the Service department for recommended repairs.
Testing the Sensing Element - Step 2 (Figure 6-6)
Raise the level in the vessel to cover as much of the sensor
as possible. Repeat the measurement made in step 1.
Readings of 1 meg-ohm or less indicate a pinhole or crack
in the sensing element insulation. Failed insulation is
not field repairable. Consult the Service department for
further assistance.
6.8 Troubleshooting Coaxial Cable
If there is water or other conductive material in the
conduit it can change the electrical properties of the coax
cable and cause the system to perform poorly. Moisture
in the conduit may not be detected by the following test.
