Electrical Contact Pressure Gauge (Pressure Switch Gauge)
-- Steady & Reliable Manufacturer --
Product Overview
Our Electrical Contact Pressure Gauges combine the local visual indication of a standard pressure gauge with integrated electrical switching contacts, enabling direct control and alarm functions without the need for a separate pressure switch or transmitter. When the system pressure reaches a user-set upper or lower limit, the contacts open or close a circuit to trigger alarms, activate pumps, shut down compressors, or control valves. The magnetically assisted contact version provides a clean, bounce-free switching action, making these gauges ideal for reliable, low-cost automation in boiler systems, water supply networks, and industrial process control.
