Differential pressure switches

Differential pressure switch 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 2 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.
