Differential pressure switches

These differential pressure switches are IP 65 protection degree and suitable for a variety of applications such as: chemical, petrochemical, conventional power station where it is required to control differential pressure, level, flow.
The sensing element is a metallic diaphragm with 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.
