Differential pressure gauge model DPGT43HP.100

    Applications
    Acquisition and display of process values
    Transmission of process values to the control room (4 ... 20 mA)
    For measuring locations with a high differential pressure overload and/or high working pressures (static pressures), also in aggressive ambience
    Easy-to-read, analogue on-site display needing no external power

   Special features
    High working pressure (static pressure) and high overpressure safety, optionally up to 40, 100, 250 or 400 bar
    Inpidual, non-linear characteristic curves (e. g. x2 or √x for flow measurement)
   "Plug and play" with no configuration necessary
    Differential pressure measuring ranges from 0 … 60 mbar
    Hydraulic cushioning protection against rapid pressure changes

   Description
    At any point where a differential pressure has to be indicated locally, and, at the same time, a signal is wanted to be transmitted to a central controller or remote control room, the model DPGT43HP intelliGAUGE (patent applied for, among
others European Patent No. EP 06113003) can be used.
    The electronic WIKA transmitter, integrated into the model 732.14 high-quality mechanical differential pressure gauge, combines the advantages of electrical signal transmission with the advantages of a local mechanical display.
    Even if the power supply is completely lost, the differential pressure can be read securely. The rugged design of the diaphragm measuring system produces a pointer rotation proportional to the pressure.
    An electronic angle encoder, proven in safety-critical automotive
applications, determines the position of the pointer shaft - it is a non-contact sensor and therefore completely free from wear and friction. From this, the electrical output signalproportional to the pressure, 4 ... 20 mA, is produced. The
electrical zero point can also be set manually.
    These differential pressure gauges are made of highly corrosion-resistant stainless steel. A high overpressure safety is achieved by the all-metal construction and the close-fitting design of the diaphragm measuring element.
    With its high-grade stainless steel construction and robust design this pressure gauge is geared to chemical and process engineering applications. It is suitable for gaseous or liquid media, also in aggressive ambience.
    The wetted parts for these differential pressure gauges are available also in special materials such as Monel, Hastelloy or PTFE.
