Description

The diaphragm pressure switches SCH-27 are IP 65, and suitable for a variety of applications such as: food industry, cannery, pharmaceutical, petrochemical, conventional and nuclear power station, and they withstand the most unfavourable working conditions, caused by either the process fluid aggressiveness or high ambient temperature.
The sensing element is a metallic diaphragm and acts directly on the microswitch through a self-centering pivot. The simplicity of the design, without levers, cams or similar mechanism, gives the unit an exceptionally long working life.

The differential pressure switches SCH-28 are IP 65, and suitable for a variety of applications such as: food industry,cannery, pharmaceutical, petrochemical, conventional and nuclear power station where it is required to control differential pressure, level, flow. The sensing element is a metallic diaphragm with two metallic bellows and acts directly on the microswitch through a self-centering pivot. The simplicity of the design, without levers, cams or similar mechanism, gives the unit an exceptionally long working life.
