HPFM B.V., is a 100% private company, and deals with high pressure calibrations till 1.625 GPa. This will be achieved, with the full SI related units, and is based on the controlled clearance piston gage - deadweight balance system technology.
The current measurement uncertainty is 3.10-4.Pe (+/- 2.9 kg/cm2) All associated SI quantities & units within the aforementioned full scale during calibration, are 100% traceable to the EN ISO/IEC 17025 2017; accredited references. The output signals will be calibrated measured, with EN ISO/IEC 17025 2017; accredited standards, like mA, mV, V, mV/V, Pc-Bar.
Our local environmental calibration conditions, like the Te, Pe, rv are measured, recorded and filled on a 24-6-365 schedule. The center value of gravity is: 9.812.929.6 m/s2 We be able to calibrated all pressure related instructions as from 10 kPa.
As from 50 MPa, we be able to calibrate up and downwards per 50 MPa till 1625 MPa. The average duration for any high pressure calibration, like transducers, transmitters and gauges are within 3 days max. Including all associated calibration documents, like calibration reports, calibration certificates, calibration antifraud stickers and the total safe packaging for any global destinations. High pressure validation is also possible, for pressure safety valves, pressure relieve valves, pressure switches, and all static and also dynamic autofrettage procedures and sequences, as well positive and negative procedures.
Our high pressure know-how, experiences and expertise goes back for almost 40 years.
