Automotive sensors: types and description

Modern cars are equipped with a variety of electronic options. They are easy to use and have a high level of comfort. A variety of sensors helps to activate most devices, including the operation of the engine. Using sensors can detect all breakdowns in your car. Sensors also provide both a driver and the electronic system with timely and necessary information.

Most automotive sensors are located in an internal combustion engine. Without exception, all the processes, all the movements are recorded in different parts of the engine sensors. We suggest you considering a variety of automotive sensors.

Temperature sensors

The car has a number of sensors. They are responsible for a variety of temperature control units. For example, the engine has a sensor indicating the temperature at which the car engine runs. In addition, the car has a sensor responsible for the liquid cooling. Climate control is also equipped with a temperature sensor.

Pressure Sensors

It should be noted that the pressure sensors are designed to be responsible for a variety of settings. Diesel engines are equipped with a special pressure sensor in the fuel injection. More modern cars have sensors that determine the tire pressure. An automotive sensor that detects oil pressure in the engine is one of the most important sensors. The accuracy and reliability of the technical units depends on the compliance of pressure.

Airflow Sensors

Motion sensors are also called airflow sensors. Their work is connected with the car engine. Thus, the air consumption is measured in weight. Each car has own rules of the airflow.

Position and velocity sensors

Many elements move in the car engine. Now we primarily speak of the crankshaft and the camshaft. Furthermore, the throttle also opens. In order to ensure the free operation of all components some sensors are used. They need to measure the car speed and its location. Inductive sensor is one of the subspecies of automotive sensors. When using them it is possible to perform measurements of the speed and transmit information to the control unit. After it, at the right moment the control unit implements fuel injection into the cylinders of the car engine.

Exhaust gas sensors

These sensors are responsible for the structure of the exhaust gases. Environmental standards applicable to cars have been increased lately. Therefore, the usage of such sensors is necessary and required. This system also includes oxygen sensors and NOx sensors.

Oxygen sensors or lambda sensors are responsible for the accuracy in the formation of fuel and air connections in all engine cylinders.

Sensors monitor the content of nitrogen oxides of exhaust gases of your car. They are installed in the exhaust system. These sensors are equipped with two cameras. One of them provides a measurement of nitrogen oxides content. Another one is responsible for the disintegration of the materials into oxygen and nitrogen.

Magnetoresistive sensors

Cars have relatively recently started to be equipped with such sensors. Magnetoresistive sensors have a magnetic field. They determine the resistance of electronic pulses and transmitting the information to the control unit. For example, this is an automotive sensor which is responsible for the turning angle.
