Dial pressure gauge PGT23.1 series

threadedG 1/2NPT 1/2

Acquisition and display of processes Easy-to-read, analogue on-site display needing no external power Process industry: Chemical industry, petrochemical industry, oil and gas, power generation, water and wastewater 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 PGT23 intelliGAUGE® (patent, property right: e.g. DE 202007019025) can be used. Through the combination of a mechanical measuring system and electronic signal processing, the process pressure can be read securely, even if the voltage supply is lost. The intelliGAUGE® model PGT23 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 is based upon a model 23X.30 high-quality, stainless steel safety pressure gauge. 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.
