Pressure switch testing–
manual approach
Accurate calibration of pressure
switches is a critical step in
ensuring process quality and
the safe operation of equipment.
The setup is similar to pressure
gauge calibration except
now a voltage or continuity
across a set of switch contacts
needs to be read either by a
(Digital Multimeter) DMM or
the calibrator. The purpose of
the calibration is to detect and
correct errors in the set point
and deadband of the pressure
switch. Calibrators can save
you time by reducing steps
and reducing the amount of
equipment you have to bring
to the job. With the right
calibrator the entire process
can be automated.
