Locating leak detection


Product introduction

    CWT-YJ-MM-A locating leak detection controller is used to monitor environmental leaks in real time. The monitoring area can be up to 150 meters long. Once a liquid leak is detected, the controller will immediately alarm, accurately locate and display the leak position through the display, and trigger the relay action. The controller outputs relay contact signals and RS485 interface, which can be connected with various monitoring systems to realize remote alarm and control of remote equipment.


    CWT-YJ-MM-A is suitable for IDC computer rooms, data centers, smart buildings, libraries, museums, warehouses, etc..


  • Accurate locating

    The controller can accurately locate the specific location of liquid leakage with high accuracy, low error, and a detection distance of up to 1500m.

  • full functioning

    The controller has functions such as leakage alarm, disconnection alarm, and interference alarm, and can display the status of the controller through interface indicators.

  • High-definition display

    The controller's LCD high-definition screen displays leakage location, device address, baud rate and other parameters, and can be adjusted through the panel buttons.

  • RS485 Communication

    The controller outputs signals with RS485 port to upload leakage data to monitoring system to achieve real-time centralized monitoring, RS485 communication distance of up to 1,200 meters.

  • Linkage control

    The controller outputs relay contact signals, which can be linked to solenoid valves, audible and visual alarms and other equipment. When a leak occurs, the relay operates and the leak indicator light turns on. After the danger is eliminated, the controller automatically returns to normal status without manual on-site operation.

  • Stable performance

    The controllers all use industrial-grade electronic components, which can not only ensure high sensitivity during detection, but also reduce false alarms caused by various external factors. The equipment adopts electromagnetic compatibility design and has anti-surge, anti-static, anti-EFT and other protection functions.

  • Simple and easy to use

    The controller is suitable for standard DIN35mm industrial rail installation, and all on-site wiring can be easily completed through terminal blocks.

Locating leak sensing cable

Product introduction

     CWT-YJ-SLFB locating leakage sensing cable can detect leakage points at any location of the cable, and is suitable for various places where there is a risk of leakage. The cable is connected to the CWT locating leak detection controller to form a locating leak detection system with high locating accuracy and fast and reliable response. The sensing cable is made of two lightweight high-density polyethylene wires pressed around a spiral central axis. Compared with parallel structure sensing cables, the spiral structure can reduce environmental electromagnetic interference and false alarm rates, and also greatly improves the strength and safety of the cable. service life. And it has automatic recovery function and can be used repeatedly.


    CWT-YJ-SLFB is suitable for various places with risk of liquid leakage such as IDC computer rooms, data centers, water supply pipelines, smart buildings, warehouses, etc.


  • The cable is highly flexible and can be installed in complex, curved pipes and other on-site environments.

  • The resistance of the sensing cable is uniform and the error is within 1%. For a leak detection system with resistance as an important parameter, it has high stability and accuracy of detection and locating.

  • The sensing cable has a plastic connector with a unique waterproof structure, which facilitates cascading to expand the detection range. Various length specifications are available to meet various detection range needs.

  • The patented spiral structure design of the cable can not only reduce environmental electromagnetic interference and reduce the false alarm rate, but also greatly improve the strength and service life of the cable.

Working principle

    When there is liquid in contact with the sensing cable, the inner core wires of the two induction wires are connected to the liquid, forming a loop resistance, thereby causing a change in current. According to the proportional relationship between the resistance and the length of the conductor, an alarm signal is issued through the rapid calculation of the controller. giving the specific leak location.
