Reed Switch Water Level Sensor

The float integrates a magnet and the stem a reed switch at the set point.

Reed switch water level sensor.

The float s magnetic. Water level fluid level capacitive sensor how it works and how to make one duration. Gltv3 reed switch type water fuel level sensor it is done by sealed reed switches positioned inside the main shaft of the sensor. Reed switch in liquid level sensor sensotex duration.

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. The advantage of reed switch type level sender over thick film swing arm type level sender is the reed switch s durability and reliability. Additionally in reed switch level senders the float is the only moving part of the sender thereby minimizing potential mechanical failures. The reed switch has its contacts encased in a glass tube with inert gas and operates by an applied magnetic field.

Reed switches and reed sensors are used along with resistors or special reed sensors with integrated resistor to give out a potentiometric feed back across two outputs as a foamed magnetic float moves along the pcb s length. The sensor uses a magnet and a reed switch to detect liquid presence. As the magnetic float rises and falls as liquid levels change. Gltv3 reed switch type petrol level sensor it is done by sealed reed switches positioned inside the main shaft of the sensor.

The pcb tracks can be designed in such a way that a full tank gives high resistance and an empty tank gives low resistance or vice versa. 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 magnetic field generated from the inside of the float drives the sealed reed switch installed in the stem. These level sensors work on the float principle with magnetic transmission. The figure shows the float and the stem.
