Wherever the process pressure has to be indicated locally under limited space conditions and, at the same time, a signal transmission to the central control or remote centre is desired, the model PGT23.063 intelliGAUGE (patents applied for, among others Europ. patent no. EP 06113003) 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 voltage supply is lost.
The intelliGAUGE model PGT23.063 fulfils all safety-related requirements of the relevant standards and regulations for the on-site display of the working pressure of pressure vessels. An additional measuring point for mechanical pressure display can thus be saved.
The model PGT23.063 is based upon a model 23X.30 high-quality, stainless steel safety pressure gauge with a nominal size of 63. The pressure measuring instrument is manufactured in accordance with EN 837-1.
The all welded and 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 sensor, integrated into the high-quality pressure gauge, combines the advantages of electrical signal transmission with the advantages of a local mechanical display.
The measuring span (electrical output signal) is adjusted automatically along with the mechanical display, i.e. the scale over the full measuring range corresponds to 4 ... 20 mA.
