Sensing cable for liquid hydrocarbon fuels TT5000

Product Announcement from Pentair Thermal Management

Sensing cable for liquid hydrocarbon fuels TT5000-Image

TT5000 sensing cable provides distributed leak detection and location for a wide range of applications. The cable is available in a variety of lengths to provide as much coverage as needed.

TT5000 sensing cable is available in bulk reels, with connector kits or with factory installed connectors that plug together. The cable is designed for a variety of double containment applications, including tanks, trenches, and piping.

The Raychem radiation-cross linking and conductive-polymer technologies are used to make TT5000 sensing cable mechanically strong and chemically resistant. The core of the cable is constructed of two sensing wires, an alarm signal wire, and a continuity wire.

The core is encased in a conductive-polymer jacket and surrounded with a fluoropolymer braid. This rugged construction allows the cable to perform reliably in the most demanding environments.
