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 model DPGT43HP intelliGAUGE (patent applied for, among others European Patent No.
EP 06113003) can be used. The electronic WIKA transmitter, integrated into the model 732.14 high-quality mechanical differential pressure gauge, combines the advantages of electrical signal transmission with the advantages of a local mechanical display.
Even if the power supply is completely lost, the differential pressure can be read securely. 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, 4 ... 20 mA, is produced. The electrical zero point can also be set manually.
These differential pressure gauges are made of highly corrosion-resistant stainless steel. A high overpressure safety is achieved by the all-metal construction and the close-fitting design of the diaphragm measuring element.
With its high-grade stainless steel construction and robust design this pressure gauge is geared to chemical and process engineering applications. It is suitable for gaseous or liquid media, also in aggressive ambience.
The wetted parts for these differential pressure gauges are available also in special materials such as Monel, Hastelloy or PTFE.
