Applications

  • Acquisition and display of processes
  • 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 overload 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"
  • Scale ranges from 0 … 16 mbar
  • Wide choice of special materials
  • For gaseous, liquid and aggressive media, also in aggressive environments, due to all stainless steel construction
  • Safety version S3 per EN 837

Description

Wherever the process pressure has to be indicated locally and, at the same time, a signal transmission to the central control or remote centre is desired, the model PGT43HP intelliGAUGE® (patent, property right: e.g. DE 202007019025) can be used. Due to the metallic pressure element limit stop, these instruments have a high overload safety in the ranges of 40, 100 and 400 bar.

The intelliGAUGE® model PGT43HP fulfils all safety-related requirements of the relevant standards and regulations for the on-site display of the working 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 measuring instrument is manufactured in accordance with EN 837-3.

The robust 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 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.

The electronic WIKA sensor, integrated into the high-quality pressure gauge, combines the advantages of electrical signal transmission with a local mechanical display that remains readable during a power failure.
An additional measuring point for mechanical pressure display can thus be saved.
