SCH-27 Pressure Switch
Brand: KOBOLD Instruments, IncThese diaphragm pressure switches are IP 65, and suitable for a variety of applications such as: food industry, cannery, pharmaceutical, petrochemical, conventional and nuclear 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.
