SCH-28 Differential Pressure Switch
Brand: KOBOLD Instruments, IncThese Differential pressure switches are IP65, and suitable for a variety of applications such as: food industry, cannery, 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.
