APGT43.100 / 43.160 Pressure Gauge

At any point where pressure has to be measured independent of fluctuations in the atmospheric pressure and 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 WIKA APGT43.100/43.160 intelliGAUGE (US Patent No. 8,030,990) can be used.

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 APGT43.1x0 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 indication can thus be saved.

The WIKA APGT43 is based upon a model 532.54 high quality, stainless steel 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 mechanical pressure gauge, combines the advantages of electrical signal transmission with the advantages of a local mechanical display. The measuring span (electrical output signal) is set 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.

Features:

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