Liquid level sensors play an important role in the automotive industry. The safe and continued function of a car’s engine and other working parts depend on the ability for lubricants and other liquids to be measured, distributed and controlled at the right time and in just the right amounts.
In this post, we’ll overview the various automotive liquid level sensors that make it possible for drivers to get in, turn the key and go as well as the reasons many others are left frustrated and stranded in a car that doesn’t operate.
Fuel Filter Sensor
One of the most basic ways a car operates is by delivering gas to the engine. As the fuel makes its way through the gas line, a filter screens out any particles and dirt so it doesn’t get into the engine and cause issues like fuel pump failures.
With diesel engines, level sensors are an especially important component as the water that’s found in diesel fuel must be separated and kept away from the engine and other moving parts. The sensor will indicate when there is water that must be drained from the filter.
Oil Pressure Sensor
In addition to gasoline to get a motor running, lubrication of the internal parts keeps the wheels turning and things cranking. With proper lubrication, parts like the pistons and the crankshaft can move freely in the needed directions and aid the movement of the car forward.
Keeping the oil pressure at a dedicated rate also requires accurate and consistent measure.
Coolant level / Heat sensor
Coolant is the mix of water and antifreeze that’s used to keep the engine cooler while it’s running. It works by cooling the airflow under the hood. To reduce the heat happening inside the engine. A sensor used in this application provides a safety warning that your car is overheating.
As these sensors communicate with one another and detect an “issue” they activate a light on the driver’s dashboard to indicate something is off-course. This prevents wear and tear and keeps drivers safe.
