GE Druck PM 620 Pressure Module

     The PM 620 is 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 and digital characterisation allows interchangeability without set-up or calibration. The modules can be changed in a few seconds to re-range an instrument at a fraction of the cost of a new one.
  
     The pressure modules can be used in conjunction with the relevant pneumatic or hydraulic pressure station and the DPI 620 multifunction calibrator to form an integrated pressure calibrator for test and calibration of pressure instruments including transmitters, transducers, switches, gauges, indicators and recorders. Alternatively, the modules can be combined with the pressure station by a module carrier, which adds a dual channel pressure measurement capability that can be re-ranged in seconds. Pressure ranges are available from 25 mbar to 1000 bar (10 inH2O to 15000 psi) with a total measurement uncertainty, including operation over 0 to 50o C (32 to 122°F) for one year.
