Diaphragm pressure gauge with output signal

Applications

    • Acquisition and display of process values
    • Output signals 4 ... 20 mA, 0 ... 20 mA, 0 ... 10 V for the transmission of process values to the control room
    • For measuring points with increased overpressure of 40, 100 or 400 bar
    • Easy-to-read, analogue on-site display needing no external power
    • Safety-related applications

Special Features

  • No configuration necessary due to "Plug-and-Play"
  • Measuring ranges from 0 ... 16 mbar
  • Wide choice of special materials
  • For gaseous, liquid and aggressive media, also in aggressive ambience, due to all stainless steel construction
  • Safety pressure gauge S3 per EN 837

Description

At any point where the process 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 PGT43HP intelliGAUGE (US Patent No. 8,030,990) can be used.

Due to the metallic construction of the pressure elements, these instruments have a high overpressure safety in the ranges of 40, 100 and 400 bar.

Through the combination of a high-quality mechanical measuring system and precise electronic signal processing, the process pressure can be read securely, even if the power supply is lost.

The intelliGAUGE model PGT43HP fulfils all safety-related requirements of the relevant standards and regulations for the on-site display of the operating pressure of pressure vessels. An additional measuring point for mechanical pressure display can thus be saved.

 

The model PGT43HP is based upon a model 432.36 high-quality, stainless steel safety pressure gauge with a nominal size of 100 or 160. The pressure gauge is manufactured in accordance with EN 837-3.

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 signal proportional to the pressure, e.g. 4 ... 20 mA, is produced.

The electronic WIKA transmitter, integrated into the high-quality pressure gauge, combines the advantages of electrical signal transmission with the advantages of a local mechanical display.

The measuring span (electrical output signal) is adjusted automatically along with the mechanical display, i.e. the scale over the full display range corresponds to 4 ... 20 mA. The electrical zero point can also be set manually.
