Fandesensor

DR3513 series boiler steam pressure controller is a single pole double throw transfer switch (SPDT ). It can control the ON / OFF action of external circuit by detecting the change of pressure and changing the status of internal switch. It is mainly used to control the boiler water tower pressure conditioning system. The controller controls the switching on and off of the solenoid valve or electric valve. When the system pressure exceeds the set value, the microswitch acts and the blocking circuit plays a protective role on the system.
