Automating Transmitter
and Sensor Calibrations
Temperature transmitter
calibrations are often
performed without taking
into account temperature
sensor performance.
For many processes this
has been an acceptable
practice, although the
sensor typically contributes
more errors than the
transmitter.
This practice can be
problematic for critical
process measurements or
those that need a higher
degree of confidence
or accuracy.
Testing the transmitter
and its respective process
sensor together provides
a more complete test. If
performed with the proper
test equipment, error
contributions from the
sensor can be minimized
by matching the device to
the transmitter electronics.
