Reed Switch Fuel Level Sensor Working

A float an actuating rod and a resistor.

Reed switch fuel level sensor working.

The figure shows the float and the stem. The ground on the gauge must be good for the gauge to work right. Oil level sensors work the same way that traditional float switches work except for they work with oil instead of water. Reed switch fuel sender 900mm 240 33 ohm add to compare.

The sensor assembly is often referred to as a sender. Calibrated to 33 240 ohms it is made of durable 316 stainless steel. View as list grid. A float with built in magnets then triggers the reed switch relays generating a potential signal with resistance current or voltage value that increases or decreases according to the fluid level then give the signal to the gauge via wires which shows the right level reading by pointer.

This reed switch sending unit is suitable for gasoline ethanol diesel bio diesel and non potable water. The sensor uses a magnet and a reed switch to detect liquid presence. It has one terminal for battery positive a ground an illumination and the signal which is the wire to the sending unit. The reed switch has its contacts encased in a glass tube with inert gas and operates by an applied magnetic field.

Moeller electric fuel sending units receive fuel level information via the float. Senders and sensors fuel level sender reed switch. The float integrates a magnet and the stem a reed switch at the set point. View as list grid.

This combination of components sends a variable signal to the fuel gauge or an electronic device a little black box that actuates the fuel gauge. How the fuel sending gauge works the gauge has four electrical points. The electric liquid level sending unit utilizes reed switch and magnetic field technology. Oil level sensors use magnetic reed switches that are hermitically sealed in a stainless steel or plastic stem to measure oil levels and automatically turn on or off oil pumps.

The level sensor in a vehicle s fuel tank is actually a combination of three components.
