Reed Switch Fuel Level Sensor Working

The reed switch has its contacts encased in a glass tube with inert gas and operates by an applied magnetic field.

Reed switch fuel level sensor working.

Gltv3 reed switch type water fuel level sensor it is done by sealed reed switches positioned inside the main shaft of the sensor. Moeller electric fuel sending units receive fuel level information via the float. The sensor uses a magnet and a reed switch to detect liquid presence. Calibrated to 33 240 ohms it is made of durable 316 stainless steel.

How the fuel sending gauge works the gauge has four electrical points. This reed switch sending unit is suitable for gasoline ethanol diesel bio diesel and non potable water. The ground on the gauge must be good for the gauge to work right. The sensor assembly is often referred to as a sender.

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. Reed switch fuel sender 900mm 240 33 ohm add to compare.

The electric liquid level sending unit utilizes reed switch and magnetic field technology. It has one terminal for battery positive a ground an illumination and the signal which is the wire to the sending unit. 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. 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.

A float an actuating rod and a resistor. A rubber gasket is included for proper mounting. The float integrates a magnet and the stem a reed switch at the set point. Oil level sensors work the same way that traditional float switches work except for they work with oil instead of water.
