What A Linear Position Sensor Can Do

By Adriana Noton


A linear position sensor provides positioning data to the computer that handles one of many different things in a machine or mechanism. The sensor can work in everything from a machine that manufactures automobile parts to an automobile itself. Though it has many other applications, the sensor works best in a car because it can identify the position of so many things in a car's inner workings.

Automobiles have many parts in the drivetrain that need a sensor to feed information to the car's computer. The car flashes dashboard lights at you, and those lights know when to warn you because of the information the sensor provided. New technology in today's cars only works well if a linear positions sensor works on many levels. None of the features you paid top-dollar for would work without them.

Take the example of headlights that turn before you enter a curve. The headlights only know that a curve is coming because of a sensor that tells the car its position on the road and that a turn is coming. The computer can use this information to turn the headlights and anticipate the turn, and it can do that reliably over and over again.

Vehicles with parallel parking features employ this same technology to get the can parked safely. The devices send constant streams of information to the computer to alert it to the position of other cars and the roadside. The vehicle can steer itself while parking of the data that the sensors provide. The process is safe because it receives accurate positioning data.

These same units tell the vehicle the position of its throttle, transmission, brakes, camshaft, and other components. All the mechanical parts in the vehicle talk to the computer in this way. They are small units, and they keep your car on the road just as much as your hands on the steering wheel do. A mechanic has an easier time fixing a car, and a car self-regulates as you drive it.

Safety measures deploy with the help of these units. They know when an accident occurs, and they can signal the computer to deploy airbags and other safety components during the crash. The locks, windows, doors, and trunk all communicate with the car's "brain", and they are all monitored at all times. The lights at the dashboard light up for this very reason.

New vehicles use sensors to run properly, but the machines that make car parts, the parts themselves, robotic arms, medical and surgical technology, and other devices use linear position sensors to function. Medical procedures are more efficient and safer to perform. The providers can do more delicate procedures, and they can do more in a shorter amount of time.

Positioning devices allow us to have many of our modern conveniences, and they definitely help a lot of us get to and from work every day. Microelectronics and sensorics make everything more functional, easier to use, and save us more money all at the same time.
