It is well known to the driver that the tyres will not go far in the flat tyres. Insufficient tyre pressure leads to higher fuel consumption, rapid wear of tyres, as well as the movement of the car to the side during the movement. In addition, the flat tyre threatens to cause an accident with very significant consequences. According to statistics, about 250,000 people. This is exactly why the world happens to be a year in the world. Tyre pressure sensors are used to record the pressure drop in the tyre and report it to the driver. History of creation
- The sensors in the direct measurement systems of the tyres,
- sensors in the system of indirect pressure in the tyres.
The first type of sensor is used in direct measurement systems. The operating principle of the tyre pressure sensor is based on the electronic pressure measurement element in combination with the battery and the transmitting antenna. Such sensors are installed on each wheel instead of a staff valve. By using radio signals or impulses, the information from the sensor is transmitted every minute. These signals receive the antenna and transmit them to the control unit. The retrieved data is mapped to the control parameters. If the data is different, an indicator is lit on the instrument panel (or on the display). It's a battery sensor.
The antenna of the central lock is used most often as a receiving antenna, but in some systems there is a reception antenna on each sensor. The direct measurement system of the tyres may display information on the screen of the on-board computer or use its own miniature screen. In addition to the monitor lamp, text and graphical information about the status of the buses can also be displayed.
