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.
Reed switch fuel level sensor working.
A rubber gasket is included for proper mounting.
Reed switch fuel sender 900mm 240 33 ohm add to compare.
The float integrates a magnet and the stem a reed switch at the set point.
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.
The advantage of reed switch type level sender over thick film swing arm type level sender is the reed switch s durability and reliability.
Senders and sensors fuel level sender reed switch.
The figure shows the float and the stem.

Oil level sensors work the same way that traditional float switches work except for they work with oil instead of water.

It has one terminal for battery positive a ground an illumination and the signal which is the wire to the sending unit.
The electric liquid level sending unit utilizes reed switch and magnetic field technology.
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.
The level sensor in a vehicle s fuel tank is actually a combination of three components.
The sensor assembly is often referred to as a sender.
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.
The sensor uses a magnet and a reed switch to detect liquid presence.
Gltv3 reed switch type water fuel level sensor it is done by sealed reed switches positioned inside the main shaft of the sensor.
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.
