The model PGT21 intelliGAUGE^® is a combination of a Bourdon tube pressure gauge and a pressure sensor. It offers the usual analogue display, which enables reading the process pressure on site, and in addition an analogue output signal (4 ... 20 mA or DC 0.5 ... 4.5 V).

The measuring system with Bourdon tube per EN 837-1 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. That provides a pressure-proportional signal for further processing.

The intelliGAUGE^® is available as standard in scale ranges from 0 ... 1.6 bar to 0 ... 400 bar with an accuracy class of 2.5 and a 2 m round cable for the electical connection. The stainless steel case fulfils the requirements of IP65 ingress protection. The resistance to shock and vibration can be increased by the silicone oil case filling. Thus the instrument is perfectly suited for use in harsh industrial environments.

Through various options (e.g. higher accuracy class, other cable length) the pressure gauge can be matched exactly to the customer-specific requirements of each application.
