Electronic Probe Level Switches

Gems Sensors WIF water in fuel & lubricating oil switch

• The rugged WIF-1250 sensor was designed with no moving parts (conductivity) to provide compact, reliable & simple detection of the presence of water in fuel.
  • Typical applications include off-highway vehicles, heavy machinery, diesel storage tanks and generator sets.  It can also be a useful addition to fuel filters and lubricating oil tanks to sense lubricant property degradation.
  • Alternating (±DC sqaure wave) potential prevents typical metal probe material loss through electrolysis
• Suitable OEM applications with customisation available on request
