For the hard conditions and the high demands on pressure measurement in production facilities in chemical industry and other comparable branches the all stainless steel pressure gauges are the perfect fit. Stainless steel and other high-grade materials are used for the measuring system and the case to achieve resistance to aggressive media and environments.
To prevent wear based on pulsating pressures and mechanical vibrations, the housings are glycerine filled and thereby damped. The measuring system is of accuracy class 1.0, has overrange protection amounting to 1.3 times the max. rating and can be loaded up to the full scale value.
The safety execution of the pressure gauges comprises a burstproof solid front between dial and Bourdon tube, a laminated safety glass as well as a blow-out back (according to EN 837-1/S3 ).
Pressure gauges with glycerine filling are equipped with a compensation diaphragm. This diaphragm avoids a pressure rise caused by a temperature based volume expansion of the liquid filling, thus avoiding indicated errors.
