Description

The Renke RS-SJ-N01R01-1-EX is a dedicated positioning water leakage sensor engineered for critical infrastructure protection. It operates by detecting the change in electrical characteristics along a specialized sensing cable upon liquid contact, enabling it to pinpoint the exact location of a leak. This system is designed for seamless integration into industrial monitoring networks via its standard RS485 Modbus-RTU communication protocol.

Built for reliability in demanding environments, the sensor features a robust DIN rail-mountable enclosure and operates within a 10–30V DC range. Its integrated 128×64 LCD provides clear status and position readouts, while the relay output and audible alarm ensure immediate notification for rapid response in facilities such as data centers, warehouses, and manufacturing plants.

Key Features

  • High-precision leak positioning system with ±(0.5% of cable length + 0.5m) accuracy.
  • Industrial RS485 Modbus-RTU interface for seamless SCADA and BMS integration.
  • Multi-alarm output system includes a relay (250V/10A capacity), buzzer, and visual LCD.
  • Wide operating voltage range (10–30V DC) ensures compatibility with various industrial power supplies.
  • Low power consumption (0.35W) for energy-efficient continuous monitoring.
  • Durable 35mm DIN rail mounting design for secure and organized panel installation.
  • Clear 128×64 backlit LCD display for real-time status and fault diagnostics.
  • Designed for use with dedicated sensing cables (5m to 200m range, cable sold separately).

Applications

  • Continuous leak monitoring in data center raised floors and underfloor cabling.
  • Protection of warehouse storage areas for water-sensitive goods and materials.
  • Integration into Building Management Systems (BMS) for commercial and industrial facilities.
  • Monitoring of pipeline runs, pump stations, and water treatment infrastructure.
  • Early warning systems in server rooms, telecommunications hubs, and electrical substations.

Frequently Asked Questions

What is the operating voltage range for this water leak sensor?

The Renke RS-SJ-N01R01-1-EX sensor operates on a wide-range DC power supply of 10 to 30 volts. This makes it compatible with standard 12V, 24V, and other common industrial DC power systems, ensuring flexible integration into existing control panels and monitoring setups.

How does the sensor communicate with a monitoring system?

This sensor uses a standard RS485 communication interface running the Modbus-RTU protocol. This allows for direct daisy-chaining with other Modbus devices and seamless integration into SCADA software, PLCs, and Building Management Systems for centralized monitoring and alarm management.

Is the sensing cable included with the sensor unit?

No, the dedicated sensing cable required for leak detection is not included in the package and must be purchased separately. The sensor controller unit supports cable lengths from 5 meters up to a maximum of 200 meters, allowing you to select the appropriate cable for your specific installation layout.

How is the leak position accuracy calculated?

The sensor provides a positional accuracy of ±(0.5% of the total sensing cable length + 0.5 meters). For example, on a 100-meter cable, the maximum error would be ±1.0 meter (0.5% of 100m = 0.5m, plus the fixed 0.5m offset). This enables precise localization of the leak point along the cable run.
