Reed Switch Fluid Level Sensor

Magnetic float level sensor works with reed switch is a continuous level sensor.

Reed switch fluid level sensor.

Single point level switches are available in a vast range of sizes mountings materials and sensing technologies from mechanical to no moving parts which include float level sensors and switches electro optic level switches capacitive level sensors and switches and ultrasonic level sensors. Gltv3 reed switch type petrol level sensor it is done by sealed reed switches positioned inside the main shaft of the sensor. Packaging options custom packaging can be provided to meet any need. The float integrates a magnet and the stem a reed switch at the set point.

Fluid sensors and floats can be configured to function as a normally closed or form b reed switch. Iatf 16949 certified sensor manufacturer of fluid level indicators fli magnetic floats level sensors conductivity probes reed sensors reed switches nsf sensors nsf switches opto sensors photo microsensors photosensors opto interrupters opto reflective back bias proximity sensors magnetic contacts door contacts ultrasonic sensors washer level sensors brake fluid fli sensors. A form b fluid sensor containing a normally open reed switch that uses it s floating magnet to keep it in the closed position as with our horizontal mount ls03 series liquid level sensor. The sensor uses a magnet and a reed switch to detect liquid presence.

Other applica tions such as monitoring that a tank sump or overflow vessel. Gems sensors single point level switches are ideal for reliable and accurate tank level detection. Ge ding is professional in reed switch industry for over 20 years as an primary agent of rmcip reed switch and as the manufacturer of series of reed switch sensors. Coolant level sensor fluid level sensor operation basic principle the sensor is in a normally open position.

Brake fluid level monitoring in automobiles to test that the res ervoir is full. 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. The figure shows the float and the stem.

The reed switch has its contacts encased in a glass tube with inert gas and operates by an applied magnetic field. As the magnetic float rises and falls as liquid levels change. When the fluid level in the reservoir tank is low the magnet in the float activates the reed switch sending a voltage output to the customer electrical interface. Note that if the wires to the sensor are severed the reed switch appears to be open and the sensor registers low.
