nVent RAYCHEM TraceTek Fast Fuel Sensors (FFS) are fast-acting probes designed to detect hydrocarbon fuels. The sensor ignores water, but detects a thin layer of fuel floating on the surface.

The sensor's response time is typically a few seconds for light or medium weight fuels such as gasoline, jet fuel and diesel. It also responds to petroleum and some heavier fuels and heating oils, but becomes progressively slower as the volatility of the fuel decreases.

In many cases, the FFS sensor will reset after it is removed from contact with the spilled fuel and the fuel is allowed to evaporate. Some heavier fuels require soaking the sensor in isopropyl alcohol or naphtha to clean the heavier fuel residue.

The sensor can be used repeatedly without replacement until it stops resetting. The sensor fails in the "alarm" state, so the need to replace it is no ambiguity.

The TT-FFS probes are designed to work only with nVent RAYCHEM TraceTek leak detection devices. Talk to your local TraceTek representative to learn more about controller and alarm panel options. The sensor can be tested periodically with a small amount of gasoline (lighter fluid). The sensor resets when the gasoline evaporates.

DESIGN FEATURES

  • Quick response to a small amount of fuel
  • Fits many applications
  • Automatic reset after fuel evaporation time, reusable sensor
  • Easily tested with the FFS-Probe Tester
  • Intermix up to 4 FFS sensors with the TT5000 sensor cable to create a hybrid leak detection system
  • Use in EX zones by using additional safety barriers
  • Safety system component with SIL-2 rating

APPLICATION EXAMPLES

TT-The FFS should be placed in an area that is least exposed to vehicle traffic, personnel, etc. but highly likely to come into contact with any fuel spill. This includes consideration of low points in the floor where fuel can leak such as from machinery, fuel tanks, valves and filters. Placement of the sensor should be done as close to the floor as possible, which will allow quick detection of any fuel leak where possible. The body of the TT-FFS should be attached to the mounting bracket using self-locking ties or other replaceable mounting mechanism. Over time, it may be necessary to remove the sensor for equipment maintenance either to protect it from damage or to perform maintenance.

TraceTek TT-FFS Fast Fuele Sensor

An additional option is a stainless steel float designed for TT-FFS sensors. It is used to keep the TT-FFS fuel sensor on the surface of the water where fuel can be found. Sensors for outdoor use have the symbol TT-FFS-WR-xx in the code.

TYPICAL RESPONSE TIME

  • Gasoline less than 5 seconds
  • Jet A fuel less than 5 seconds
  • Diesel less than 5 seconds
  • Kerosene less than 5 seconds
  • MTBE (Methyl Tert-Butyl Ether) 12 seconds
  • Biodiesel (B100) 45 seconds
  • Crude oil 3 minutes

NOTE: Time to alarm observed in the field depends on equipment configuration and field conditions. Typical response time at 20°C is given.


AVAILABLE VARIANTS

TRACETEK TT-FFS-100 TT-FFS-200

Available in sensor height variants of 100 mm or 250 mm each with different cable lengths, terminated or unterminated with MC metal connectors.

INDOOR VERSION

The standard version (probe TT-FFS) meets the requirements of FM 7745 for diesel leak detectors for detecting leaks of this fuel in commercial buildings. It improves the safety of diesel generators used for backup electrical power, reducing the risk of fire in the event of a leak. The TT-FFS probe can be used for the same purpose near diesel fuel storage tanks used to power boilers or other heating equipment in commercial buildings.
