How Does A Coolant Level Sensor Work
How Does A Coolant Level Sensor Work. Once the sensor detects low coolant, the driver is alerted by a light illuminated on the dashboard. Once the coolant drops to a certain level, the float follows the level, the reed switch is removed from the magnet, and contracts the reed switch open.

Once the coolant drops to a certain level, the float follows the level, the reed switch is removed from the magnet, and contracts the reed switch open. View our full range of level sensing solutions. The tip of the ect sensor protrudes into one of the cooling system.
I.e., The Sensor Reads The Position Of A Float That Rides On The Surface Of The Coolant In The Resevoir, Or “Surge” Tank That Was Added.
Hence it is known as coolant sensor or. Iirc, the contacts are closed with the float up (level is ok), and contacts open with the float down (level is low). The coolant level sensor works with a float that contains a ring magnet.
A Coolant Level Sensor Is Used To Detect The Presence Or Absence Of Critical Coolant Fluid Inside A Coolant System.
Once the sensor detects low coolant, the driver is alerted by a light illuminated on the dashboard. Water has conductive minerals in it therefore conducts electricity. With the float up, the light should be off, with the float down, light should be on.
The Ring Magnet Closes The Reed Switch Inside When There Is Enough Coolant In The Radiator.
Or it can involve electric sensors with two electrodes that are placed at the bottom of the expansion tank. Radar or microwave is also a continuous level sensor. The ring magnet closes the reed switch inside when there is enough coolant in the radiator.
In General, They Are A Float Sensor In The Coolant Recovery Tank.
The use of coolant level sensors enables equipment uptime, ensures the proper operation, and extends the equipment service lifespan. The advantages and disadvantages of coolant sensors are also covered. The ring magnet closes the reed switch inside when there is enough coolant in the radiator.
The Coolant Level Is Normally Monitored By Either A Switch Mounted In The Radiator.
It is one type of temperature sensor used to measure temperature of the engine coolant. An engine coolant temperature sensor or ect measures the temperature of the liquid coolant. This page describes coolant sensor basics and mentions coolant sensor working operation.
