- 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
