3.27 Diaphragm Pressure Switch

Brand: Nuova Fima

These diaphragm pressure switches are IP 65, and suitable for a variety of applications such as: chemical, petrochemical, conventional power station, and they withstand the most unfavorable 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.
