  • Gems WIF-1250 LevelSwitch

    Gems® type WIF-1250 sensors are innovative, no-moving parts solutions specifically designed to detect the presence of water in fuel. They are an ideal solution for OEM’s of off-highway vehicles, locomotive and generator sets. They are also idea for use with fuel filters. Based on reliable conductivity technology, WIF-1250 sensors are built from robust nickel plated steel for compatibility with temperatures up to 257°F and are suited for the most challenging environments or applications. A 5-second delay prevents “slosh” actuation. The sensor is easily mounted in any position.
