Model CDM 3801 B

The INVALCO Model CDM is a diaphragm-operated Pressure Switch for pneumatic or hydraulic control. The unit is equipped with one or two snap-acting three-way Micro Valves® to provide on/off output to one or more controlled circuits at pressures up to 100 psi. Since the Micro Valves® are completely isolated from the diaphragm, and also isolated from each other, various control output pressures and media may be used in the same CDM pilot.

CADM/CADMEX Series Pneumatic and Electric Pressure Switches

The INVALCO Model CADMEX is furnished with an explosion-proof Micro Switch providing dependable operating for systems requiring electrical control. The standard Micro Switch has SPDT contacts and UL and CSA hazardous area approval. An optional switch arrangement is available with DPDT contacts and spring-loaded design. The DPDT Micro Switch does not have the adjustable differential capability of the SPDT and, therefore, is actuated and released at approximately the same pressure. The CADMEX is offered with a choice of four spring ranges providing a wide range of flexibility in application.Please click the graphic on the right or the link at the bottom of the page for further information.
