ETS.RS – Fuel level sensor with digital output

The sensor includes a number of smart technical solutions ensuring an extensive lifespan and high reliability:

  • sensor circuitry is embedded in an elastic compound that guarantees complete protection against salts and humidity and thus ensures long-term outstanding operation in high-stress environments. The sensor’s components are made of materials that do not enter into chemical reactions with fuels or lubricants, or with their components.
  • The sensor is equipped with a built-in voltage stabilizer ensuring stable operation under fluctuations of supply voltage.
  • A built-in averaging algorithm cancels out reading noise due to tank sloshing.

A built-in self-diagnosis algorithm allows to recognize certain disturbances in the operating environment and in the sensor’s functioning
