  • Long life (10+ years) — reduces maintenance cycles
  • Intrinsically safe design — ideal for hazardous locations
  • Standalone deployment — ideal for remote sites
  • Waterproof enclosure — supports harsh outdoor conditions

Technology

FLD-xRTD Self-Powered Monitoring Module Technology

Smart Hydrocarbon Detection

The FLD xRTD interfaces with Naftosense passive sensing cables and probes that react to hydrocarbons such as gasoline, diesel, and crude oil. The module uses advanced signal processing to detect leak events quickly and accurately.

Intelligent Alarm Filtering

The system incorporates adaptive thresholding to reduce false alerts caused by contaminants like grease or residual hydrocarbons—delivering more reliable alarm performance.

RTD Output for Easy Integration

A major advantage is its Pt100 RTD signal output, allowing direct integration into:

  • Existing temperature transmitters
  • PLC / SCADA systems
  • Wireless monitoring platforms

This approach eliminates the need for specialized interfaces.

Multi-Zone Monitoring

  • Supports monitoring of multiple sensing cable sections (up to 4 zones)
  • Detects multiple leak points simultaneously
  • Enables better coverage across large assets like pipelines
