Applications

• Acquisition and display of process values
• Transmission of process value to the control room, 4 ... 20 mA, 0 ... 20 mA, 0 ... 10 V also as individual, non-linear characteristic curves
• Pressure measurement independent of fluctuations in the atmospheric pressure
• Monitoring of vacuum pumps, packing machines, determination of condensation pressure and vapour pressure in liquids

Special 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

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 model APGT43 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 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 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 highquality 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.
