Product Information

Product Description

Authorized North America Distributor Stamp

This sensor is suited to locations that contain fuel storage tanks or fuel transfer stations and is especially ideal for remote locations that use diesel fuel generators. The ropeFuel sensor is a rope-type leak detector that connects to any sensorProbe or securityProbe RJ-45 Intelligent Sensor Ports and facilitates the detection of fuel and other liquids.

The ropeFuel sensor detects the presence of liquid hydrocarbon fuels at any point along its length. The sensor detects the liquid, triggers an alarm, and pinpoints the location of a leak within a meter, or a foot. Typically this sensor can detect:

  • Gasoline
  • Diesel #1
  • Jet A\B\5\8
  • JP-4\5\7
  • Kerosene

As this sensor is a rope type, it is perfect for lying beneath fuel tanks, usually found being used with diesel generators in remote locations where early warning of fuel leakage or theft is vital to maintaining the power supply, either of a UPS or as the main power source.


  • Comes fully assembled and includes the rope portion that is the liquid sensing cable, the non-sensing leader cable (from the rope to the sensing module) and the main sensing module. Also includes a 5 foot CAT5 extension cable.
  • Full autosense Sensor module. SecurityProbe and SensorProbe (seen note below) will auto-detect the presence of the ropeFuel sensor.
  • LED activates when liquid is detected by the sensor.
  • Sensor reports critical status if cable integrity is broken, cut, or unplugged.
  • Sensing Rope Cable can be pre-ordered from a 1 meter minimum to any custom run length of up to 5 meters. Non-sensing Cable comes in a standard 10 foot run length and can be extended up to 165 feet (50 meters).
  • NOTE: The ropeFuel sensor is only compatible with the securityProbe, securityProbe 5E and newer sensorProbe2 shipped after October 2009. If you have an older sensorProbe2 or sensorProbe8 base unit, please contact us for upgrade details.
