DPGT43.100 / 43.160 Pressure Gauge

At any point where a differential pressure 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 DPGT43.100 / 43.160 intelliGAUGE 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. An additional measuring point for mechanical pressure indication can thus be saved.

The WIKA DPGT43.100/43.160 is based upon a model 732.51 high quality, stainless steel pressure gauge with a nominal size of 100 or 160. The pressure gauge is manufactured by EN 837-3. These differential pressure gauges are made of highly corrosion-resistant stainless steel and feature an all-metal media chamber sealing. Therefore no elastomer sealing elements are required so that a better long-term leak tightness is ensured. A high overpressure safety is achieved by the all-metal construction and the close-fitting design of the measuring element.

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 differential 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.
