Differential pressure switch sensor Function This sensor operates on the differential between internal and external pressure to actuate a switch. It provides a reliable indication of pressure difference in the monitored system. Easy to install Very easy to use with a connection that can be quickly modified to fit existing configurations. Key benefits Enables immediate detection of pressure changes, supports straightforward integration with minimal downtime, and helps protect equipment by signaling abnormal pressure differentials. Compatibility and physical attributes Designed for simple integration with common installation practices. Size and material are not specified here; please consult the product datasheet for exact dimensions, construction material, mounting options, and performance ratings such as pressure range and electrical specifications. Use scenarios 1) HVAC systems and air handling units to monitor duct pressure and indicate filter condition or trigger control actions 2) Industrial filtration and process lines to detect pressure drop across filters or traps, signaling maintenance needs 3) Pneumatic or hydraulic circuits to monitor for leaks or blockages by tracking differential pressure across valves or components
