TraceTek TT7000-HUV UV-Stabilized Outdoor Aggressive Acid LeakUV-stabilized porous-fluoropolymer outdoor aggressive & fuming acid leak sensing cable

Q: How does TT7000-HUV improve upon TT3000 for outdoor and high-temperature acid service?

While TT3000 is designed for indoor sub-fabs up to +85 °C, TT7000-HUV upgrades to fully perfluorinated PFA/PTFE polymers rated from -40 °C to +120 °C and replaces the translucent green braid with a carbon-black UV-stabilized microporous fluoropolymer braid that withstands years of direct desert or tropical sunlight plus fuming nitric acid and oleum.

Q: Will outdoor rain trigger TT7000-HUV?

Yes—because TT7000-HUV is a conductive-liquid sensor, rainwater bridging the sensing wires will register as a conductive liquid alarm and report the wetted location. On uncovered outdoor pipe racks, install TT7000-HUV inside the bottom of a drip channel/insulation cladding or use alarm-panel rain-suppression logic.

Q: Why is TT7000-HUV widely used in refinery HF alkylation and mining SX-EW plants?

Hydrofluoric acid (HF) and 98 % sulfuric acid (H₂SO₄) rapidly attack glass fibres (destroying optical leak cables) and standard engineering plastics. Perfluorinated PFA/PTFE with carbon black is one of the very few materials completely immune to both 49 % HF and 98 % H₂SO₄.

Q: Can TT7000-HUV be spliced onto TT3000 where an outdoor pipe enters an indoor building?

Yes. Both share the exact same 4-wire 20.0 Ω/m electrical characteristic and modular connector interface, so an indoor TT3000 zone can transition directly into an outdoor TT7000-HUV zone on the same controller channel.
