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
  • Pressure measurement independent of fluctuations in the atmospheric pressure
  • Monitoring of vacuum pumps and packing machines
  • Measurement of condensation pressures and determination of vapour pressure in liquids


Special Features

  • No configuration necessary due to “plug-and-play”
  • Scale ranges from 0 … 25 mbar absolute pressure
  • Easy-to-read analogue display with nominal sizes 100 and 160
  • High overload safety, long service life due to metallic media chamber sealing
  • Media chamber protected against unauthorised access

Description

The model APGT43 intelliGAUGE (US patent no. 8,030,990) can be used wherever pressure measurement has to be independent of fluctuations in the atmospheric pressure. The instrument serves for the on-site display with a simultaneous signal transmission to a central control or remote centre.”

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 voltage supply is lost.

The intelliGAUGE model APGT43.1x0 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 APGT43 is based upon a model 532.54 high-quality, stainless steel pressure gauge with a nominal size of 100 or 160.

The pressure measuring instrument is manufactured in accordance with DIN 16002.
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 electronic WIKA sensor, integrated into the high-quality absolute 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.
