Pneumercator LS600LDBN-1-F Float-Type Leak Sensor, Non-Discriminating, Buna-N Vertical Float with Fault Detect – (SKU: LS600LDBN-1-F) is a compact secondary containment leak sensor for aboveground and underground storage tank systems. It provides simple “wet/dry” indication using a vertical magnetic float, ideal for sumps, dispenser pans, turbine enclosures, and double-wall steel tank interstitial spaces.

Non-Discriminating Float Leak Detection: A Buna-N float travels on a brass stem and actuates an internal hermetically sealed reed switch when liquid reaches the trip point. Because the sensor is non-discriminating, it responds to either fuel or water in the containment area, making it suitable for general leak alarm applications where any liquid ingress must be detected.

Fault Detect Supervised Wiring: The LS600LDBN-1-F includes Pneumercator’s fault-detect option so compatible consoles can monitor both leak status and field wiring integrity. The supervising electronics enable detection of open-circuit, short-circuit, or ground fault conditions on the sensor loop, improving system reliability and simplifying troubleshooting.

Durable Buna-N/Brass Construction: Wetted materials include a Buna-N float, brass stem, and 304 stainless steel/nylon body components, offering broad compatibility with petroleum products and many site liquids. A factory-attached 25 ft (7.5 m), 2-conductor, 22 AWG PVC-jacketed cable allows easy routing from the containment point back to the monitoring console through standard riser or conduit openings.

Integration & Approvals: Designed for use with Pneumercator LC2000 and TMS-series tank monitoring systems that support fault-detect leak sensor inputs, the LS600LDBN-1-F provides alarm contacts for audible/visual indication and external interlocks. The sensor is listed for use in appropriate classified hazardous locations when installed, wired, and barriered according to code and controller instructions.
