Submersible Pump Protector

Duwan Environmental LB-05Water Leak DetectorSummary:

Submersible Pump Water Leakage Protection Relay, also known as Miniature Comprehensive Protection Relay，This is a specialized resistor and motor temperature signal for detecting the water sensitivity inside a submersible pump..Electrode Sensors Utilized in Sensors,When leaks occur within the pump casing or abnormal temperatures are detected.,The control relay emits the corresponding control signal.,To facilitate staff in dealing with the water leakage from the pump..The controller implements a series of anti-interference measures in its circuit design.,Operates reliably in environments with severe electromagnetic interference.

Feature:

Relays are used to detect the resistance and temperature signal of water sensitivity inside the submersible pump.ptcOr temperature switch).When the resistance of the water sensitivity inside the submersible pump falls below the given value,Relay activation;After power was restored following a shutdown for fault inspection, the relay resumed its operation.,When an open circuit signal or a high resistance is detected, an alarm is triggered.,Simultaneously, the relay operates..

Normal conditions,Fault signal output is a normally closed signal (note):Standard configuration is normally closed,Regular Open Signal Requires Customization,In the event of a power outage or input signal failure,The normally closed signal has been converted to a normally open signal..

The system can separately display alarm types.,The system can also be manually reset to resolve faults..

Water-sensitivity resistor based on standard setting,Customers with special requirements are welcome to contact us in advance..

  LB-05Leak ProtectionSimple circuitry,Compact in size,Lightweight,Effort-saving,High stability,And features a tube socket insertion structure,Ease of Maintenance.

Fault Detection

      When the oil chamber leaks, the probe detects a resistance value.20KAt that moment, the fault disappeared, and the protector returned to its initial state.(Direct Return Characteristic)No content provided.1sPlease provide the Chinese content to be translated.5sDelays are inversely proportional to input resistance; the smaller the input resistance, the shorter the delay time, and vice versa.

When the motor cavity leaks, the probe detects a resistance value.35KAt that moment, the fault disappeared, and the protector returned to its initial state.(Immediate Return Difference Feature)No Chinese content provided.1sNo Chinese content provided.5sThe delay is inversely proportional to the input resistance; the lower the resistance, the shorter the delay time, and vice versa.

      When the junction box leaks, the probe detects a resistance value. 35KAt that moment, the fault disappeared, and the protector returned to its initial state.(Immediate Return Difference Characteristic)No content provided.1sNo Chinese content provided. Please provide the text to be translated.5sThe delay is inversely proportional to the input resistance; the lower the resistance, the shorter the delay time, and vice versa.

      When the winding overheating probe detects temperatures exceeding the prescribed limit(The temperature value is determined by the overheated probe selected by the user.)When disconnected, the corresponding indicator light illuminates and the fault output relay operates. When the temperature returns to below the specified level and re-contacts, the fault is cleared.LeakageThe protector has been restored to its initial state.
