Pressure Gauge Model MGS20 DN63

Features Pressure Gauge Model MGS20 DN63

These Solid-Front instruments are built in accordance with safety specifications of EN 837-1 “S3” and ASME B40.1.
The safety construction consists of a solid separating wall in stainless steel, placed between the scale and the elastic element and a blow out back which is released from the case whenever an internal pressure, due to leaks, is created or the elastic element is broken. A leak tight fit is ensured if the instrument is filled with a dampening fluid to prevent damage due to vibration. These instruments are designed for use in chemical and petrochemical processing industries, and in conventional power plants. They are built to resist the most severe operating conditions created by the ambient environment and the process medium
