Duwan Environmental Leak and Overheat Dual Detector Relay Protector Introduction
Leakage+The dual-sensing relay features simultaneous detection of leakages in the submersible pump and overheat conditions.
The leak protection feature of the submersible pump is designed to detect any leakage within the pump. When leakage occurs inside the pump, the control relay will emit the corresponding control signal.
② The motor overheating protection function is designed to detect the temperature of the stator winding inside the submersible pump. When an abnormal temperature condition occurs in the stator within the pump body, the control relay will emit the corresponding control signal. Staff will promptly perform maintenance and repairs on the pump. The control relay incorporates a series of anti-interference measures in the circuit design, enabling it to operate in environments with severe electromagnetic interference.
