Differential Pressure Switch Model 24
Brass or Polysulfone®, Adjustable Ranges 1 to 45 PSID
The 24 Series Differential Pressure and Vacuum Switches offer a unique blend of compact size, excellent performance, environmental protection and attractive price. Available with brass or Polysulfone® pressure connections, the Model 24 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 setpoint adjustability. The force-balanced design gives the Model 24 excellent vibration resistance.
The Model 24 Differential Pressure and 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.
