Calibrating and Testing
Thermocouple Sensors
Thermocouples are common in industry
because they are inexpensive and cover a wide
temperature range.
They should be tested during commissioning
and again when removed from a process to
verify that tolerances were met. Additionally,
thermocouples may be tested at regular
calibration intervals and when suspected of
failing to meet their performance specifications.
Often thermocouples need to be calibrated prior
to use for mapping a temperature controlled
enclosure, or they have to be calibrated for use
as a temperature standard.
Due to the unique characteristics of
thermocouples, they are best calibrated in
situ (in place) by comparison to a temperature
standard. However, in situations where that
is not practical, it is necessary to remove
the thermocouple and place it in a precision
temperature source such as a dry-well.
