Digital Primary Standards > DPG10G (Gauge) Digital Primary Standards

Digital Primary Standards

Digital Primary Pressure Standards are built around an original concept first introduced by DESGRANGES & HUOT in the early 80's. The DPG technology combines a piston-cylinder assembly with an electronic force cell. They are the only pressure standards to associate the metrological performances of pressure balances with the convenience of digital transfer standards. Measuring can be done from zero to full scale. Ideally suited as working standard in calibration laboratory, including accredited laboratories and especially dedicated to gauge and high absolute pressures.

Digital Primary Standards > DPG10A (Absolute) Digital Primary Standards

Digital Primary Standards

Ideally suited for the calibration of low gauge pressure, absolute pressure, Air Data Test Systems and avionics instruments. A distinct advantage of the Digital Piston Gauge over traditional piston gauge technology is that it can perform calibrations from zero pressure upwards. In traditional piston gauges, the lower limit is determined by the mass of the piston, but with the DPG range this mass ca be tared out.
