Fuel level sensor DUT-E

Precision fuel level sensor DUT-E is designed for precision fuel level measurement in tanks of vehicles, trucks, tractors, road-building machinery, fixed installations.
DUT-E is used as a standard fuel level sensor or as an additional sensor together with AVL, FMS or vehicle tracking systems.


DUT-E has the standard SAE 5 bolted flange and is mounted in the standard hole of the fuel level sensor or the special hole in the vehicle fuel tank.


  • Electrical noninteraction with tank body;
  • Allows cutting “at place” up to 30% of its initial length without recalibration;
  • Strong cast metal body;
  • Protection of sensor output from short circuit;
  • Protection from voltage overload (up to 50 V);
  • Sensors are delivered calibrated, i.e. sensors are interchangeable and there is no necessity to make tank normalization when you replace DUT-E sensor;
  • Stable and more exact output signal;
  • New bayonet lock and small overall dimensions of the outside sensor part;
  • Possibility of sealing. 

Output signals

DUT-E is produced with versions of output signals:

  • DUT-E A5: analog, output voltage range 1.5 - 4.5 V;
  • DUT-E A10: analog, output voltage range 2.5 - 9 V;
  • DUT-E-485: digital, protocol DUT-E COM;
  • DUT-E-232: digital, protocol DUT-E COM;
  • DUT-E-F: frequency output 500 - 1500 Hz.
