The FLD-02W-SP is a highly sensitive oil-on-water sensor designed to detect as little as 1ml of hydrocarbons floating on water. Designed for vertical applications, permanently immersed in salt or ground water. This line of durable sensors can even respond to heavy, low lying hydrocarbon fumes or gases due to the multiple leak sensing wire construction. UV/ozone resistant, it is specially engineered for reliable operation during long-term immersion in water and in icing conditions and is suitable for polar applications. The maximum length of sensor probe is limited to 48in (122cm / 1.2m). The sensing probe can be wired to the acquisition module through an optional jumper cable with a maximum length of 1000ft (300m). Advanced measurement techniques and data treatment algorithms are used by Naftosense acquisition modules to provide quick detection in a very wide temperature range. The sensor is reusable and easily detachable for cleaning.
The FLD-O2W-SP probe is designed to be used exclusively with any model of Naftosense monitoring modules providing industry-standard analog outputs, dry contacts, or serial communication protocols for flexible integration with third-party monitoring panels or PLC.
FLD-O2W-SP is a passive simple element and is safe for installations in hazardous locations when connected to intrinsically safe field box or wired through an approved Zener barrier. Please contact Naftosense for additional information.
