Honeywell Sensotec Frequently Asked Questions

When should I use an absolute pressure sensor rather than a gage pressure sensor?

The primary consideration concerns whether the atmosphere plays a role in the application for which the pressure sensor is being used. If any part of the application is exposed to the atmosphere, such as an automotive emission system or in level measurement in a open tank, a gage pressure sensor should be used. But if the atmosphere has no effect on the application, either type of pressure sensor can be used. However, when measuring extremely high pressures, such as those found in hydraulic applications, an absolute pressure sensor is typically used.

(Consult the Pressure Reference Chart to compare how the various pressure sensors reference pressure.)
