Naftosense FLD-HSC High-Reliability Hydrocarbon Sensor

The FLD-HSC 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. Rapid detected hydrocarbons include gasoline, diesel, jet fuel, motor oils, lube, and transformer oils, etc. The FLD-HSC sensor cable is offered as factory- terminated modular sensor with heavy-duty waterproof connectors (model -C), or as fixed-length multi-section encapsulated sensor string with oil-resistant 10-ft leader cable (model -L).

The sensor is specially engineered for reliable operation in both indoor and outdoor conditions. The waterproof connectors of -C model allow short-term immersion in water. The encapsulated -L version is designed for long-term immersion. The semi-conductive sensor material is extremely durable and can withstand long-term exposure to temperatures more than 212°F / 100°C. The sensor cable is UV resistant, anti-termite and anti-rodent and can be used in tropical applications

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 monitoring module. The version FLD-HSC-ML allows up to 8 sensor sections to be connected to the same monitoring module while the version FLD-HSC-TL is limited to 3 sensor sections.

When used for applications in hazardous areas, the sensor cable shall be wired to an intrinsically safe acquisition modules, or alternatively through a Zener barrier to a sensor module installed in the safe zone. Please contact Naftosense for additional information.
