Leak Detector
Detail
Product OverviewXW-DC-03 Two-channel non-locating leak detector is a simple and cost-effective liquid leak detection device, which can connect two sense cables at the same time for detection.The relay contact signal and 485 signal output by the detector can be integrated with various monitoring systems to realize remote monitoring.

FeaturesWith two groups of independent detection channels, can connect two leakage detection cables as the same time. A single channels can connect 500 meter leak detection cable to monitor the leakage status of each area which suitable for multiple leak detection areas.
Using industrial grade electronic components, can not only ensure high sensitivity, but also reduce the false alarm caused by various external factors. Adopt electromagnetic compatibility design,anti-surge, anti-static, anti-EFT and other protection functions.
Support to adjust sensitivity by software according to the requirements of the detection environment (the adjustment range is within 1cm-20cm of the cable length).
Adopt standard industrial modules and DIN rail mounting, all connections can be easily done through terminals. When leakage occurs, the relay act and leakage indicator light up, and the controller automatically restores to normal state after danger elimination, no need manual operation.
When detects liquid leakage, the LED leakage indicator on the panel is steady on and the internal buzzer gives an alarm sound.

Operation Principle
XW-DC-03 Two-channel non-locating leak detector connect with sense cables to detect 1 or 2 areas, and the leakage data can be uploaded leakage data to the host computer through RS485 signal. Sensor relay output signal can be used to control peripheral equipment such as acousto-optic alarm, telephone dialer, SMS module, switch value collection module, etc.

Buttons and indicators
Install the detector in a secure indoor collection box or cabinet where it is easy to maintain and check. Avoid high temperature, high humidity, vibration, corrosive gases, and other electronic interference sources. The detector buckle is mounted on a standard 35 mm DIN rail.
Non-locating leak detection system is composed of detector, outgoing cable, sense cable and related accessories. Connect cables when the power supply of detector is disconnected.
|
Sense cable |
Connect the red and black core wires of the outgoing cable to the wiring terminals R1and B1(or R2 and B2)of the detector separately, and then lay the sense cables to the detection area. |
|
Relay output |
Two sets of output NO/NC contactcan be connected to monitoring system, also can be connected to alarm devices to output alarm signal. When controlling high current equipment, it is necessary to add secondary relays to expand the contact load capacity, otherwise the detector may burn out. Two sets of RS485 output terminals for cascading multiple detectors. |
|
Power Supply |
DC 9~30V power input (DC12V is recommended to ensure long-term working stability). If voltage too low, it will not work properly, and if voltage too high, the controller will burn out. |
