Description
Wherever the process pressure has to be indicated locally and, at the same time, a signal transmission to the central control or remote centre is desired, the model PGT43 intelliGAUGE® (patent, property right: e.g. DE 202007019025) can be used.
The model PGT43 is based upon a model 43x.30 high-quality, stainless steel safety pressure gauge with a nominal size of 100 or 160. The pressure measuring instrument is manufactured in accordance with EN 837-3.
The intelliGAUGE model PGT43 fulfils all safety-related requirements of the relevant standards and regulations for the on-site display of the working pressure of pressure vessels.
The robust 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, e.g. 4 ... 20 mA, is produced. The measuring span (electrical output signal) is adjusted 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.
The electronic WIKA sensor, integrated into the high-quality diaphragm pressure gauge, combines the advantages of electrical signal transmission with a local mechanical display that remains readable during a power failure.
An additional measuring point for mechanical pressure display can thus be saved.
