Water-in-Fuel Sensors.

process inset
Entratech custom designs and manufactures Basic Probe Sensors or Smart Sensors with or without internal EOL (End Of Line) resistors to interface with vehicle ECM. Our engineers work with leading OEM manufacturers.

Robust construction of these Hi-Performance Sensors are built to withstand the rigors of marine, military vehicles, heavy-duty off-road, and on-road applications. They are corrosion resistant, meet requirements of ISO 19921 fire resistance test and UL Fire Test Standards. 1/2"- 20 thread standard.

The Stainless Steel versions can be used as Marine WIF Sensors (commercial marine water-in-fuel sensor) that meet ABS standards.
Stainless Steel WIF Sesnor (single probe)
high-1
Rugged water-in-fuel probe available with or without internal EOL (End Of Line) resistors engineered to interface with Engine Control Module (ECM). Can be used in any robust off-road, on-road vehicle, marine or generator set application. For use in marine machinery spaces that must conform to ABS marine standards.
  • ABS marine standards
  • Meets requirements of ISO19921
  • Designed to UL Separator standards
  • Stainless steel and ceramic construction
  • SAEJ1926 straight thread with O-ring sealing design
  • Packard GT-Series 2-terminal connector
Stainless Steel WIF Sesnor (dual probe)
high-1
Rugged water-in-fuel probe designed with or without internal EOL (End Of Line) resistor value per manufacturers requirements to interface with Engine Control Modules (ECM). Can be used in any robust off-road or on-road vehicle, marine or generator set application.
  • 1/2 - 20 straight thread with O-ring sealing design (RACOR style, shown above)
  • M14 x 2.0 thread with O-ring sealing design (FLEET GUARD style)
  • Ampseal 16 DELPHI-Series 2-terminal connector
  • Available as: passive, 82.5K Ω (Cummins style, 220K Ω (JD ECM style)
Bowl Mount WIF Glass Filled Nylon Sensor
black sensor-2
Rugged water-in-fuel probe designed with internal circuit board to detect water contamination at a pre-determined level. On board anti slosh and a unique (patent pending) probe current shut off circuitry provide long service life even when water is sensed and not drained for extended times. Can be used in any robust off-road, on-road vehicle, marine or generator set application.

  • Glass filled nylon construction
  • 1/2 - 20 straight thread with O-ring sealing design (RACOR style, shown above)
  • M14 X 2 metric thread with O-ring sealing design (FLEET GUARD style)
  • Packard GT-Series 3-terminal connector
  • 12/24 VDC
