The FLD-HSC-TL is a high-performance passive hydrocarbon detector designed specifically for detecting the unwanted presence of a wide range of liquid hydrocarbons. This multiplexed sensor cable provides quick reaction to light and heavy hydrocarbons and can be used in outdoor environment. The detected hydrocarbons are primarily gasoline, diesel, jet fuel, motor oils, lube and transformer oils, etc. The FLD-HSC-TL sensor cable is offered as factory-assembled modular sensor with heavy-duty waterproof connectors (variant -C), or as fixed-length encapsulated sensor string with 10-ft leader cable.
Naftosense is the only rope style sensor in the world that can detect a small volume leak of refined fuels in under 30 seconds. With cleanable, reusable sensors and a 10-year factory warranty on the entire leak detection system you can rest assured and quickly gain ROI while protecting your facility, and staff from flammable fuel leaks.
The sensor is specially engineered for reliable operation in both indoor and outdoor conditions. The waterproof connectors of -C version allow the sensor to be immune to short-term immersion in water. The encapsulated version is designed for long-term immersion in water in demanding outdoor conditions. The semi conductive sensor material is extremely durable and can withstand long-term exposure to temperatures in excess of 100°C/212°F. The sensor cable is UV resistant, anti-static, anti-termite and anti-rodent and can be used in tropical applications.
- Product has FM7745 approval
- Detects refined fuels in under 30 seconds
- Re-usable sensors
- 10-year warranty
The sensor cable contains all the wiring necessary for long-range applications and for the connection in series of several sensors to the same NAFTOSENSE acquisition module. FLD-HSC-TL allows up to 3 sensor sections to be connected to the same module.
When used for applications in hazardous areas, the sensor cable shall be wired to an intrinsically-safe acquisition module, or alternatively through a Zener barrier to a sensor module or controller installed in the safe zone. Please contact NAFTOSENSE for additional information.
Typical detection times:
- Unleaded Gasoline: < 30 seconds*
- Diesel/Jet Fuel: < 30 seconds*
- Light Crude Oils: 4-5 minutes
- Heavy Crude Oils: 8-10 minutes
- Motor/Bunker Oils: 10-13 minutes
*These performance metrics are validated by FM Approvals
