MIEPL make SS/MS Powder Coated Pressure Gauges for Ammonia are based on the proven Bourdon tube measuring system. On pressurization, the deection of the Bourdon tube, proportional to the incident pressure, is transmitted to the movement via a link and indicated. The modular design enables a multitude of combinations of case materials, process connections, nominal sizes and scale ranges. They also have the Temperature scale in correlation to the pressure.
