Application fit

Is TraceTek TT1000 / TT1100-OHP right for your machine?

Detects and pinpoints the exact metre of water, chilled-water or condensate leaks beneath data-centre raised floors, around CRAC/CDU liquid-cooling manifolds, and along suspended overhead piping.

Fixed installation

Suitable

TT1000 lays flat under raised access floors, in drip trays and around AI server liquid-cooling CDUs.

Free-hanging vertical run

Suitable

TT1100-OHP adds a capillary wicking polyester braid that wraps directly under horizontal/vertical overhead chilled-water pipes.

Immersion & wet locations

Suitable

Non-hygroscopic fluoropolymer core sheds water and resets immediately after wiping dry.

Energy chain / drag chain

Not suitable

Static building/facility leak sensing cable; not for moving machinery drag chains.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

How does a 4-wire conductive-polymer leak detection cable calculate the exact distance to a water leak?
The cable contains two insulated copper loop wires and two black conductive-polymer sensing wires with a calibrated resistance of ~20 Ω/m. When conductive water bridges the two black sensing wires at distance L, it forms a precision Wheatstone / voltage-divider circuit. The controller measures the resistance ratio to compute L within ±0.5 % of total cable length while supervising all four wires for breaks.
Why should we use TT1100-OHP instead of TT1000 on overhead chilled-water pipes?
Smooth TT1000 is hydrophobic so it dries instantly on floors, but a tiny slow drip running along the underside of an overhead pipe might bead past a smooth cable. TT1100-OHP adds a capillary wicking polyester overbraid that absorbs and spreads even a single drop across the sensing wires.
Will TT1000 corrode or leave green copper residue after repeated water leaks?
No. Unlike bare exposed stainless-steel or copper wire-rope sensors that suffer galvanic corrosion and trap lint, TT1000 encapsulates its metallic conductors inside smooth, chemically inert carbon-fluoropolymer jackets.
Which TraceTek cable should we use for acids, alkalis or diesel fuel instead of water?
Use TT3000 for indoor acids, bases and semiconductor chemicals; TT7000-HUV for outdoor concentrated fuming acids; TT5000 for diesel/jet fuel and hydrocarbon oils; or TT5001 for fast-response organic solvents.
