Float level sensor 351ADBU

Float level sensor 351ADBU

Product characteristics

  • Level measurement on reed-contact basis
  • Connection with flange
  • Various connector types: inc Deutsch, AMP Superseal, or cable outlet
  • Available with pipe length up to 800 mm
  • Material: stainless steel, PA12
  • Measurement resolution at intervals of 10-35 mm (standard 20 mm)
  • Temperature range from -30 °C to +110 °C
  • IP67 protection class

• With temperature contact

The float level sensor 351ADBU was specially developed for SCR exhaust technology. As the necessary urea requires a defined temperature range for stability, the float level sensor has an additional circuit for connection with an external heating and cooling circuit. This keeps the tank content durable without any extra piping.
