423-6434 Fuel (Water) Level Sensor Assembly
Cat® Active Water Level Sensor with Electronic Module
Description
Active sensor that requires an external power supply and includes a reliable level switch to provide a high water level warning for fuel separator applications. Uses a capacitive principle with a reliable design and no moving parts. Can be used as a ground switch or a high-side switch. Suitable for engine-mounted applications.
Features
- Compact design with no external electronic module
- For use in severe conditions (high vibration and high temperature)
- Can be installed or serviced without tools
- Source switch or logic ground switch
Applications
- Water in fuel
- Cat level sensors are specific to the application or tank. Refer to your Operation and Maintenance Manual or contact MECHSC for more information.
