Application fit

Is TraceTek TT5000 right for your machine?

Purpose-built for wet sumps, underground storage tank (UST) interstitial spaces, airport hydrant fuel trenches and data-centre belly-tank generator rooms where water is always present but only hydrocarbon fuel leaks must trigger an alarm.

Fixed installation

Suitable

Installed in double-containment fuel transfer pipes, generator day-tank pans and airport Jet A-1 hydrant pits.

Immersion & wet locations

Suitable

Can remain submerged in water or damp soil without false alarms, yet triggers when a thin sheen of fuel contacts the jacket.

Offshore platform & shipboard deck trays

Suitable

Passive 4-wire loop qualifies as an Intrinsically Safe 'Simple Apparatus' (Ex ia IIC) when driven through an approved zener barrier.

Energy chain / drag chain

Not suitable

Static hydrocarbon containment sensing cable; not for dynamic machinery drag chains.

FAQ

Questions engineers ask first

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

How can TT5000 detect electrically non-conductive hydrocarbons like diesel and jet fuel while completely ignoring conductive water?
Unlike water-sensing cables (TT1000/TT3000) which rely on the liquid itself to conduct electricity between two exposed wires, TT5000 keeps its two conductive-polymer sensing wires sealed inside a water-impermeable jacket separated by an internal gap. Surrounding the core is a specially formulated silicone-elastomer layer that does not absorb water, but swells forcefully when exposed to liquid hydrocarbons—mechanically pinching the two internal 20 Ω/m sensing wires together to trigger the alarm and distance calculation.
Can TT5000 and TT1000 be connected to the same alarm panel in a data-centre generator room?
Yes. Because both TT5000 and TT1000 use the exact same 4-wire ~20.0 Ω/m voltage-divider architecture, they use the same TTSIM / TTDM-128 monitoring modules and can even be daisy-chained in separate zones.
When should we choose TT5001 / TT5001-HUV instead of TT5000?
Choose TT5000 for refined fuels (diesel, gasoline, Jet A-1, kerosene, hydraulic/lube oil). Choose TT5001 (indoor) or TT5001-HUV (outdoor UV-stabilized) when you need sub-minute fast response to volatile organic solvents (MEK, acetone, toluene, xylene, benzene) in pharmaceutical or chemical plants.
Is TT5000 safe to install inside Class I Division 1 / ATEX Zone 0 fuel sumps?
Yes. The sensing cable contains no energy-storing components (inductance/capacitance are negligible) and qualifies as an Intrinsically Safe 'Simple Apparatus' per IEC 60079-11 / UL 913 when connected through an approved intrinsic-safety zener barrier.
