ZJK-SP leakage overtemperature dual detection relay, also known as submersible pump leakage protection relay, was developed by Nanjing Kangzhuo Environmental Technology Co., Ltd. It is specially used to detect the water sensitivity resistance and motor temperature signal in the submersible pump. The sensor uses an electrode sensor. When a water leak occurs in the pump body or the temperature is abnormal, the control relay will send a corresponding control signal so that the staff can deal with the water leak from the pump. The controller has adopted a series of anti-interference measures on the line design, and can work reliably in the environment with very serious electromagnetic interference.
ZJK-SP leakage overtemperature dual detection relay is used to detect the resistance of the water sensitivity in the submersible pump and the winding temperature signal (PTC or temperature switch). When the resistance of the water sensitivity in the submersible pump is detected to be lower than the given value, the relay will act; the relay will continue to work after the power failure is checked and the fault is re-energized. When the temperature signal is detected as an open point signal or the resistance is large, the alarm will be triggered. At the same time, the relay operates.
When normal, the fault signal output is normally closed (note: the standard configuration is normally closed, and the normally open signal needs to be customized). When the power is disconnected or the input signal fails, the normally closed signal becomes a normally open signal.
Alarm types can be displayed separately, and faults can be reset manually.
Water sensitivity resistance is set according to the standard. Users can contact in advance if they have special needs.
ZJK-SP water pump overheat protector is simple in circuit, small in size, light in weight, low in power consumption, high in stability, and adopts a tube insertion structure for easy maintenance.
ZJK-SP water pump overheating protector has been in use since the time of sale. If you need technical assistance during use, the company has set up a professional customer service for marketing services to provide users with free technical advice, installation and commissioning guidance before, during, and after sales Questions from users.
