There are three pressure generation stations, also available in ATEX approved versions for stand- alone use in hazardous areas:
PV 621 – pneumatic pressure generator for pressures 95% vacuum to 20 bar (300 psi)
PV 622 – pneumatic pressure generator for pressures 95% vacuum to 100 bar (1500 psi)
PV 623 – hydraulic pressure generator for pressures up to 1000 bar (15000 psi).
Each pressure station is designed for stand-alone operation as a pressure generator and can replace conventional hand pumps and gas bottles to provide greater efficiency and ease of use. They can be used on the workbench or combined with a reference instrument, such as the DPI 104 they can be used as comparators and pressure calibrators.
Combining any of the pressure stations with a PM 620 pressure module and the DPI 620 calibrator creates a uniquely capable, self-contained pressure calibrator.
