Fuel sensor GW 7-3012L;H



  • L – low resolution
  • H – high resolution

Material – antimagnetic stainless steel.

The basic construction component consists of a flange and a square tube welded together. The measuring system is placed inside the tube. The float with a magnet moves along this tube and operates the magnetic switches. As a result, the output value of the selected electrical quantity depends on the fuel level height.

The measurement system is connected as a voltage divider.

The Fuel Sensor is intended for mounting to tanks with a 40mm hole.

The use of the fuel gauge must be specified in the order.
