Industrial Water Leak Detector
This industrial water leak detector adopts unique AC detection technology, which effectively avoids the problem of water leakage sensitivity decreased due to oxidation of the immersed electrode for a long time. We offer 485 output and switch dry contact output. It can be connected to the on-site PLC, industrial control instrument, configuration screen, or configuration software. The maximum distance of the external leakage electrode can reach 30 meters, the external water leak rope of up to 30 meters. This is an industrial water immersion sensor.
- Model: RS-SJ-*-2
- MOQ: 1 PCS
- Delivery date: within 24 hours
- Price: $23.1
About - Water Leak Detector
Wired water leak sensor description
Our company uses alternating current to collect the inductance parameters of stagnant water to accurately distinguish whether water is immersed, and can even distinguish between pure water and tap water (the tap water is the default detection object, if you want to detect pure water, please give special instructions). Because of the use of alternating current detection, the electrode will not produce electrophoretic polarization even if it is immersed for a long time. It does not rely on special electrodes to achieve long life and reliable detection. —This technology is our company’s patent and has been authorized by the Patent Office. Our company reserves the right to pursue legal liabilities for any counterfeiters.
In addition to this industrial water leak detector, we also have a positioning water leak detector that can display the location of the water leak in real-time when it detects a water leak.

Application - Water Leak Detector
The water leakage sensor is widely used in communication base stations, hotels, restaurants, computer rooms, libraries, archives, warehouses, equipment cabinets, and other places where water accumulation is required to alarm.
Water leak detector wiring
1. Power supply and 485 signal wiring
Wide-voltage power input can be 10~30V. When wiring the 485 signal line, pay attention to the two wires A and B not being reversed, and the addresses of multiple devices on the bus cannot conflict.
2. Relay interface wiring
The standard equipment is equipped with 1 relay output, and the two outgoing wires are normally open contacts.
3. Use of leaking rope
Customers who buy our line-type water leakage sensor, please pay attention when connecting the leaking rope. The black line is the water leakage sensor line, and the yellow line is the support frame. The black sensor lines at both ends of the leaking rope should not touch each other.
FAQ- Water Leak Detector
Use alternating current to collect the inductance parameters of stagnant water to accurately distinguish whether flooding occurs.
First find out the leaking location, then close the main valve, repair the leaking place, clean up the stagnant water, and finally open the main valve.
You can continue to use the sensor after cleaning up the accumulated water of the water leak sensor.
To protect the patented technical parameters, please contact us for a manual.
Possible reasons:
- The computer has multiple COM ports and the selected port is incorrect.
- The device address is wrong, or there are devices with duplicate addresses (the factory defaults are all 1).
- The baud rate, check method, data bit and stop bit are wrong.
- The host polling interval and waiting response time are too short, and both need to be set above 200ms.
- The 485 bus is disconnected, or the A and B wires are connected reversely.
- If the number of equipment is too much or the wiring is too long, the power supply should be nearby, add 485 boosters, and add 120Ω terminal resistance at the same time.
- The USB to 485 drivers is not installed or damaged.
- The equipment is damaged.
