Gauge Pressure Calibration

The Mensor Calibration Laboratory is fully equipped with state of the art calibration standards capable of performing gauge pressure calibrations.

  • Pneumatic Pressure Media: gauge pressure calibration for any full scale pressure up to 6000 psig
  • Hydraulic Pressure Media: gauge pressure calibration for any full scale pressure up to 30,000 psig

Mensor's lab is accredited to ISO 17025 by A2LA.

Gauge pressure is zero-referenced against atmospheric pressure. Calibration of the zero point is as simple as opening both the pressure and the reference port to atmospheric pressure. Calibration of readings above zero requires an appropriate high accuracy gauge pressure standard.

Calibration of full scale pressures below 5 psig is more complex. Deadweight testers are limited in their ability to generate very low gauge pressures. Mensor has developed special techniques to calibrate gauge pressure instruments that have full scale ranges below 5 psi. The white paper "Low Pressure Measurements" describes these techniques and limitations. Mensor is fully aware of these issues and has been the leader in very low pressures instruments for many years. 

Differences between the various types of pressure are described in the video below.
