FLD-x48 Extreme Environment Monitoring Module

FLD-x48 enclosure contains one or two self-powered intrinsically safe monitoring modules for sensors detecting leaks of refined products or crude oils in extreme environmental conditions. The FLD-x48 controller is engineered for outdoor installation in challenging environmental conditions. Its measurement frontend is designed for interfacing with reusable, fully passive hydrocarbon sensor cables and sensing probes manufactured by Naftosense.

The multiplexed architecture of the acquisition module allows up to 8 individual sensor sections not exceeding 82 ft (25 m) per FLD-x48.

Advanced measurement techniques and data treatment algorithms are used to provide intelligent thresholding for eliminating the nuisance alarm due to the presence of motor/lube oils, greases, residues of old leaks, etc.

The outputs of the acquisition module emulate standard Pt100 RTD for direct interfacing to temperature transmitters. This feature allows cost-efficient interfacing to third-party wireless transmitters available worldwide and easy testing and troubleshooting using a regular multimeter.

The inputs and outputs of the controller are available from industrial-grade terminal strip inside the outdoor-rated enclosure. The FLD-x48 contains monitoring modules that are self-powered by a non-replaceable Lithium Thionyl battery with expected operational life of more than 12 years even in arctic conditions.


FLD-x48 is approved for installation in classified locations according to FM, Atex, IECEx and other North American approvals. Designed only to be used with all Naftosense sensors and 3rd party hard wired or wireless resistance transmitters.
