Clark Solutions Model 24 Differential Pressure Switch 011

The 24 Series differential pressure and vacuum switch offers a unique blend of compact size, excellent performance, environmental protection and attractive price. Available with brass or polysulfone® pressure connections, the Model 24 Pressure Switch will stand up in your most corrosive applications. The precision snap-acting switch and sensitive diaphragms combine to provide a narrow deadband and repeatability of approximately ±1% of range span. The convenient, externally accessible adjustment screw is multi-turn to provide easy set point adjustability. The force-balanced design gives the Model 24 excellent vibration resistance. The Model 24 Vacuum Switch was designed to be a compact, cost-effective differential pressure switch for applications such as proof-of-flow, filter monitoring, etc. It depends on two opposing diaphragms to sense pressure on the "High" and "Low" pressure outputs of a system. The resulting pressure differential is transmitted through a linkage to a snap-action electrical switch, providing an output when a pre-set difference is exceeded. This set point can be easily modified while under pressure via an external adjusting screw. This adjustment "pre-loads" the actuation mechanism, which results in excellent vibration-resistance . Straight pressure and vacuum versions, with a single diaphragm, are also available.
