3.27 Diaphragm Pressure Switch
Brand: Nuova FimaThese 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.
