    Description
    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 inliGAUGE （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 inliGAUGE 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 highquality,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 compley 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.

    Design and operating principle
     The diaphragm （1） separates the media chamber （3） and the reference pressure chamber （2） with absolute pressure zero
     Pressure differential between media chamber （3） and reference pressure chamber （2） will deflect the diaphragm （1）
     In case of an overpressure overload the pressure element will be protected by a contoured metal bolster
     The deflection is transferred from the pressure chambers through bellows or corrugated tubes （4）, transmitted to the movement via the connection rod （5） and indicated
