Transmille multi-product calibrators support pressure measurement and calibration using these pressure modules which connect to the dedicated pressure module interface on the rear panel of the meter. The pressure modules cover the range from 350 mBar to 10,000 PSI. A 5 PSI differential module and a ±1 Bar vacuum module are also available. Pressure modules are available with a standard accuracy of ±0.04%.
Pressure modules are supplied with calibration coefficients, up to 3 coefficients can be stored into the calibrator to allow direct display of pressure. An unlimited number may be stored in the ProCal software. Calibration of a pressure gauge can easily be performed by connecting a hand pump to both the pressure module and the gauge under test, apply pressure and compare readings from the gauge against the reference pressure module for both rising and falling pressure.
