In any application where the process pressure has to be indicated locally, and, at the same time, signal transmission to a central controller or remote control room is needed, the PGT23 intelliGAUGE can be used. Through the combination of a mechanical measuring system and electronic signal processing, the process pressure can still be read, even if the power supply is lost. The PGT23 intelliGAUGE fulfills 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 the mechanical pressure indication is no longer necessary.

The PGT23 is based on a high-quality, stainless steel pressure gauge with a solid-front case (Type 23x.30) with nominal sizes of 4" or 6". The pressure gauge is manufactured in accordance with ASME B40.100 and EN 837-1.

The durable, fully-welded 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. The encoder is a non-contact sensor and therefore completely free from wear and friction. From this, the pressure-proportional, 4 to 20 mA electrical output signal is generated.

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 to match the mechanical display, i.e. the scale over the full display range corresponds to 4 to 20 mA. The electrical zero point can also be set manually.
