Figure 1: Water in Fuel Sensor

General Description

The purpose of the sensor is to detect the presence of

water in diesel fuel. The sensor is mounted inside of the

fuelfilter and has two main output signal stages, low

level and high level, which identify the presence and

absence of water. The output signal level is changed

when water reaches a defined water level in the fuel

filter.

Operation

Basic Principle

The operation of the sensor is based on the resistive measurement method. Water is detected because it has a lower

resistance than diesel fuel. Measurement of fluid resistance is performed between the two electrodes (for sensor options

with two electrodes), or between an electrode and a ground (for option with single electrode).

Packaging Options

Custom packaging can be provided to meet any need, please contact Littelfuse Engineering for details.
