PGT23 PRESSURE GAUGE WITH ELECTRICAL OUTPUT SIGNAL

Mechanical Pressure Gauges

Manufacturer

Wika Instruments

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.

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.

Applications:

Acquisition and display of processes
Output signal 4 ... 20 mA for the transmission of process values to the control room
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

Features and Benefits:

No configuration necessary due to "plug-and-play"
Signal transmission per NAMUR
Measuring ranges 0 ... 0.6 bar to 0 ... 1,600 bar
Easy-to-read analogue display with nominal size 100 or 160
Safety version S3 per EN 837
