WIKA DPGT43HP 帶過壓保護全鋼電接點差壓壓力表 適用于所有介質(zhì)

 Differential pressure gauge with electrical output signal
Universal version, high overpressure safety
Models DPGT43HP.100 and DPGT43HP.160

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 bs 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
    Individual, 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

   Debion
    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 inbliGAUGE (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 compleby 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 b of the pointer shaft - it is a non-contact sensor and therefore compleby 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-bl 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, Hasbloy or PTFE.
