Fuel level sensors

Fuel level sensors measure how much fuel is in the tank and pass the reading to the gauge on the dashboard. Here you’ll find float sensors with a 0 to 190 Ω resistive output in 19 lengths from 100 to 550 mm, suitable according to the manufacturer for fuel, oil and other liquid tanks.

Fuel level sensors

Float-type fuel level sensors turn the movement of the float into a 0 to 190 Ω resistive signal, which many common level gauges use. Before buying, check that your gauge works with the same resistance range. The sensors run on 9 to 32 V and, according to the manufacturer, draw no more than 60 mA.

The measuring rods come in 25 mm steps from 100 to 550 mm. Choose by tank height: according to the manufacturer, the tank should be 10 to 25 mm taller than the sensor length. The measuring resolution is 10 to 21 mm according to the manufacturer.

The sensor is fixed to the tank with a five-hole mounting flange, and M5 screws and a 2 mm thick gasket are included. The IP67 rating protects against dust and brief immersion, and the operating temperature range is −30 to +75 °C. When fitting, disconnect the battery, work without naked flames in a well-ventilated area and check the flange for leaks afterwards.
