INDUSTRIAL
THERMOCOUPLES
General Maintenance Parameters
THERMOCOUPLE DO's:
- DO check in place.
- DO replace at established, proper
intervals.
- DO have good connections throughout the circuit.
THERMOCOUPLE DO NOT's:
- DON'T reinsert at different immersions.
(Avoid decreasing the immersion).
- DON'T use for accurate measurements
at lower temperatures after being exposed to higher temperatures.
- DON'T use in defective protecting
tubes.
- DON'T insulate with used insulators.
If there is a reversal in the thermocouple circuit the indication
will be down scale. A "double-reversal" in the circuit
will give an upscale but erroneous reading. Keep the "Red"
color coded leg negative throughout the circuit to avoid these
reversals.
