Modern vehicles are a range of different systems, interconnected. The wheels are the part of the vehicle, from which performance depends on the safety of people is directly located in the vehicle cabin. Therefore, experts advise to regularly check tire pressure. To simplify this procedure, there is a special TPMS system. What is this system and what is the principle of its actions? On this and many other things - read further in the article.

Tire pressure sensor, which is the function of the sensor

Tire pressure monitoring system is a rather complex multifunctional device designed to perform a function to prevent a vehicle with a low degree of paging. In many ways, modern transport this system is included in the basic car package, because for several European countries, America and Asia, its installation is mandatory, although such control is established without much difficulty and on old cars.

It is worth noting that in addition to controlling the pressure, this device performs a number of important functions, such as accelerating the wheel, measuring the battery voltage and tires. To date, the cost of such sensors varies from three to four thousand rubles per kit, installed on each wheel.

TPMS tire pressure monitoring system from which the design is

This equipment works at the expense of the sensor installed on the disk, inside the tire. The device includes a number of items:

1. Tire pressure sensor.
2. Reception antenna.
3. Liquid crystal display.
4. Control block.

The principle of work is based on the perception by a block of signals that proceed from the sensors. The last component is a complex device comprising:

1. Antenna, which transmits the received signal to the control unit.
2. Battery.
3. Electronic measurement and control mechanisms.
4. Air pressure sensor.
5. Temperature sensor.

Principle of operation of the tire pressure sensor

Transmission of pressure information in the wheel on the block occurs every 60 seconds. As an antenna, the receiving signal from each wheel can be used by the central locking component. A separate component that perceives pulses from the sensors is mounted on some cars. It is located in the wheel arch. Such a solution makes it possible to control the pressure in each wheel, as well as output all the data on the liquid crystal display in the cabin.

Tire pressure sensor installation location

Most often, this sensor is mounted instead of a regular valve. As for the batteries located in it, the manufacturer took care of this. The battery is able to maintain the sensor performance for seven-ten years. But it is not necessary to change it, after this period, a new item is mounted in place. Therefore, when the sensor is selected, the used - even the seller is not able to say how many years they have been used before dismantling and laughed on the shelf.

Control system with general antenna four wheels

When the antenna is received from the antenna to the control unit, it compares this information with factory parameters. In case the pressure level below the norm, the control lamp lights up on the display. Sometimes it is accompanied by sound alert, which indicates that the pressure in one of the wheels is below the norm. However, in what exactly the wheel is unknown. The car owner must determine how specifically the wheel drops.

Control system with four individual antennas from each wheel

In more expensive devices, control is much easier. If four individual antennas are installed in the car, a signal is displayed on a special panel that exactly the tire is at the moment. The principle of operation of the sensor is to obtain and transmit information through an antenna to the side of the onboard computer. Also car owner are available data on the level of pumping of each wheel in real time.

What is the difference, the advantages and disadvantages of each system

Advantages of the control system with a general antenna for four wheels - light and sound notification of pressure reduction in one of the wheels, a small cost.

The disadvantages of the control system with a common antenna for four wheels - information is not displayed on the panel, in which wheel the pressure has decreased, the driver needs to determine it independently.

The advantages of the control system with four separate antennas for each wheel - control the tire pressure is much easier, information is displayed on exactly which tire is descending, the bus owner in real time can monitor the pump level of each wheel.

Disadvantages of the control system with four separate antennas for each wheel - a big value.

Varieties of tire pressure control systems
Special caps with color indicator, advantages and disadvantages

The first type is most primitive. They are special caps with color indicator. Mounted instead of standard on the wheel swap valves. The principle of this sensor is very simple. When the pressure in the wheel is less than two atmospheres, the color of the cap becomes yellow. If less than one atmosphere is red. It will be green in the case if the pressure level in the wheel will be two or more atmospheres, i.e. it will be normal.

Advantages - Easy installation and low cost: There is no need to mount antennas, additionally buy a control unit. Among the shortcomings it is worth noting low informativeness. After all, you can find out whether the wheel is lowered, only manually, putting the vehicle to the parking lot. In the process of movement, such equipment is simply useless. However, it is still much easier to look at the color of the caps, rather than to twist and measure the pressure using the tester on each wheel.

It is worth highlighting enough common control systems "X-Pressure" from Pirlyli. The basic models of Optic include four caps installed on the valves. About the decrease in pressure in the wheel they indicate a color change, which is quite convenient. However, this will not help in the case of a slowly descending tire on the go.

radiordators, Advantages and Disadvantages

Radiorders are more progressive products. They are mounted on discs using clamps or instead of a regular valve. In addition to these sensors, you should buy a set of electronic elements - display, control unit, antenna. This option is much more expensive than the first one. However, do not forget about reliability.

The system will always work, and even when driving at a hundred kilometers per hour, the driver with maximum accuracy will know the current pressure in the wheels. And if you forget, the system will warn you automatically, something or a different wheel descends. As you know, diagnose the breakdown on the go (especially if it is not a leading, but the rear wheel) is quite difficult, and even more so on the tires with a low profile.

bluetooth communication systems for information on the on-board computer, on a smartphone or tablet, dignity and disadvantages

To date, there have been a mass of devices that support the Bluetooth system. They are able to transmit information both on the on-board computer and on your tablet or smartphone. It is very convenient, however, the cost of such systems leaves much to be desired.

How to buy tire pressure sensor on Aliexpress, how to find and order the desired thing inexpensive with free shipping (detailed instructions)

1. Registration on Aliexpress is the first and mandatory step. Of course, you can find goods, the purchase of which does not require account registration, however, when trying to purchase something, you will be asked to create a personal profile.
