The model 612.20 capsule pressure gauge is based upon the proven capsule measuring system. The capsule element measurement principle is suitable for very low pressures. On pressurisation, the expansion of the capsule element, proportional to the incident pressure, is transmitted to the movement and indicated.
The modular design enables a multitude of combinations of case materials, process connections, nominal sizes and scale ranges. Due to this high variance, the instrument is suitable for use in a wide range of applications within industry.
The case and the bayonet bezel are made from stainless steel. The material of the process connection is a copper alloy.
For mounting in control panels, the capsule pressure gauges can, depending on the process connection, be fitted with a mounting flange or with a triangular profile ring and mounting bracket.
The scale ranges of 0 ... 6 mbar to 0 ... 600 mbar or 0 ... 2.4 inH2O to 0 ... 240 inH2O and the vacuum and +/- scale ranges ensure the measuring ranges required for a wide variety of applications.
