Fuel Level Sensors
Reed Switch
Reed switch fuel level sensor with corrosion-resistant construction, long service life, and multi-fuel compatibility
Overview
Overview of the Reed Switch
Reed switch sensors measure tank height with a magnetic float and a ladder of reed switches on the stem. As the float moves, switches close in sequence and the resistance seen by the gauge changes. There are no sliding electrical contacts on the resistor card, which is the main reliability difference versus a classic swing-arm tank unit. The design suits petrol, diesel, oil, and hydraulic fluids, with selectable resistance curves for standard gauges.
