XDB320 Adjustable Mechanical Pressure Switch
Features
● Use a built-in micro switch and sensing hydraulic system pressure.
● Conveys the electrical signal to electromagnetic directional valve or electric motor.
● Make it change directions or warn and closed circuit so as to achieve the effect of system protection.
Typical Applications
● Intelligent IoT constant pressure water supply.
● Energy and water treatment systems.
● Medical, agricultural machinery and testing equipment.
● Hydraulic and pneumatic control systems.
● Air-conditioning unit and refrigeration equipment.
● Water pump and air compressor pressure monitoring.
