The GE Druck PM620-14G PM620 Pressure Module is part of the latest development in digital output sensor technology incorporating a number of key innovations to allow pressure re-ranging of compatible equipment. A simple screw fit makes both the pressure and electrical connections without the need for tools, sealing tape, cables or plugs. The module costs a fraction of fixed range instruments and can be calibrated independently, allowing users to benefit from reduced inventory, shared resources, lower cost of ownership and less down-time for annual calibration checks. The DPI 612 series utilizes PM 620 interchangeable pressure modules to allow for in-field re-ranging to the highest accuracy and most suitable range for any application, while combining any of the PV620 pressure stations with a PM620 pressure module and the DPI620 calibrator creates a uniquely capable, self-contained pressure calibrator.
