The FLD-PHD is a sensor designed to detect a wide range of hydrocarbons. Designed for horizontal applications this flexible sensor is suitable for both above and below ground deployment. With a maximum sensor length of 80' you can cover smaller areas with this configure-to-order rope style sensor. With up to 1000' of lead wire you can easily monitor smaller assets. The FLD-PHD sensor cable is offered as stand-alone sensor connected in factory with 10 ft (3 m) direct-burial/UV-resistant leader cable. On request, the length of the leader cable can be extended up to 1000 ft (300 m).
The sensor is specially engineered for reliable operation at very low temperatures and is suitable for polar applications. It is fully sealed and not affected by permanent immersion in water, year after year. The length of the sensing section is limited to 50 ft (15 m). The semi-conductive sensor material is extremely durable and can withstand exposure to temperatures in excess of 212°F (100°C). The sensor cable is fully passive, anti-termite and anti-rodent and can be used in sealed/buried applications.
When used for applications in hazardous areas, the sensor cable will be wired to an intrinsically-safe sensor box, or alternatively through a Zener barrier to a sensor module installed in the safe zone. Please contact Naftosense for additional information.
