PGT23.100 / 23.160 Bourdon Tube Pressure Gauge

At any point where the process 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 PGT23.100/23.160 intelliGAUGE can be used. Through the combination of a mechanical measuring system and precise electronic signal processing, the process pressure can be read securely, even if the power supply is lost.

The intelliGAUGE WIKA PGT23 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 PGT23 is based upon a model 23x.30 high-quality, stainless steel safety pressure gauge with a nominal size of 100 or 160. The pressure gauge is manufactured in accordance with EN 837-1.

The all-welded, robust bourdon tube 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 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.
