Honeywell Sensotec Frequently Asked Questions |
What is a True Gage Pressure Sensor?
Illustration of True Gage Pressure Sensor
A True gage pressure sensor is a bonded foil strain gage-based pressure
sensor designed to measure applied pressure referenced to current atmospheric
pressure. A true gage pressure sensor employs a dual diaphragm. One side
of the diaphragm has the pressure to be measured applied while to second
diaphragm, required to prevent moisture and other air particles from entering
the sensor is vented to reference the current atmospheric pressure.
A true gage pressure sensor operates in the same way as a bonded foil strain
gage-based pressure sensor. As pressure is applied to a diaphragm, pressure
is transmitted to a gaged element via a mechanical connection, such as a
bolt. As the gaged element is deflected, strain gages, which are bonded
to the element, reflect this as a change in resistance. The bridge circuit
identifies the resulting change in electrical resistance as a change in
applied pressure to the sensor.
(Consult the Pressure Reference Chart
to compare how the various pressure sensors reference pressure.)
Note: Sensotec is one of only a few companies offering true gage pressure
transducers. It also unique in offering a second diaphragm that protects
the sensor from corrosion and damage by venting to air with humidity and
dirt.
