Fuel sensor GW 7-4011


Features – Covered float.

Material – antimagnetic stainless steel.

The basic construction component is a flange welded to two co-axial tubes. The inner tube contains a measuring system with magnetic switches. A 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 outer tube serves as a protection of the float, and, in addition, dampens the impact of sudden changes of fuel levels on measurement, for example at turning of construction machines.

The Fuel Sensor can be equipped with a reserve switch.

The measurement system can be connected as a rheostat or 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.
