High Differential Pressure (DP) Switch

Description: The High Differential Pressure Switch is a precision monitoring device designed to detect pressure variation across filters, strainers, pumps, or flow systems.
It activates an alarm or control output when the differential pressure exceeds a preset limit, indicating filter blockage ,system restriction, or abnormal flow conditions.
Built with robust materials and high sensitivity, it ensures safe, efficient, and reliable operation across industrial, fuel handling, and process applications.
