Pressure measurements are performed in many sectors of industry, from absolute pressure gauges in the aircraft industry to sphygmomanometers in the medical sector, from tyre pressure gauges for vehicles to (smart) transmitters in the process industry. All of these can be calibrated at Caliz B.V.
For liquid pressure a dead weight tester is used for a stable measurement.
For gas gauge pressure, nitrogen is used as feed pressure and under atmospheric pressure is created using a vacuum pump. The pressure is controlled using the standard pressure calibrator.
A transmitter or sensor without display can be calibrated by measuring a voltage or current compared to the pressure exerted.
