Tire pressure sensor and its application

Tire pressure plays an important role in increasing the manageability of the car, saves fuel, extends the life of tires and, as a result, significantly improves the safety of driving. It is almost impossible to test it without a special device. But the difference of only 0.3 bar can be critical and worsen the reaction of the car to braking or changing direction. And dangerous can be, as well as low pressure, and increased. Deviation from the established norm can lead to deplorable results. For example, the excess can quite provoke an explosion of the tire directly in the process of motion. The conclusion is one: it is necessary to constantly monitor the pressure in the tires of the car.

For the control, pressure gauges are traditionally used, which do not always have a high accuracy of readings. Virtually every driver has such a device in the glove compartment, but few of them regularly use it. The measurement procedure itself is not fun, and most drivers ignore this event. At present, special systems are used to monitor the tire pressure. They are included in the package only expensive foreign cars. However, you can purchase the system yourself and install it on the car. The advantages of using these devices are quite obvious. In many cases, they can become a guarantee of traffic safety and save someone's life.

The system of automatic control includes independent sensors of indications and an information block. Data transmission to the control module is carried out by means of a radio signal. The tire pressure sensor is mounted on each wheel, and the control unit with the screen is mounted in the car's interior. The screen displays information about the status of the parameters separately for all wheels. If the current reading deviates in one of the buses beyond the set interval, an alarm is triggered. At the request of the driver, it can be sound, light or complex. If the tire pressure sensor outputs the current value within the specified interval - the system operates in the passive mode. The driver can set the permissible parameters independently, depending on the specific model of the car and tires.

Depending on the brand of instruments, the time interval for measuring the readings is set within 5-7 seconds. Updating of the information on the screen is performed either with the set time interval, or when the current pressure changes by 0.05-0.07 Bar from the previous one.

The weight of modern sensors for external use does not exceed 10 grams and not more than 35 grams for the internal one. Each tire pressure sensor has its own battery, designed for continuous operation up to five to seven years, depending on the manufacturer.

Monitoring systems are constantly being improved. Currently, devices are produced that allow you to control not only the air pressure inside the wheel, but also its temperature. The principle of operation of new systems is similar. The tire pressure sensor is made in a hybrid version and allows the measurement of pressure and temperature parameters. The procedure for installing the system on the car is greatly simplified. The sensors are mounted quickly and do not require special qualification, the internal ones are attached to the disk when mounting the tires, and the external ones are screwed onto the nipple instead of the cap.

It should be remembered that the tire pressure monitoring system installed on the car is an auxiliary and in no way can replace a person. In any case, the driver must regularly check everything himself for safety reasons, and in the presence of a system on the car, monitor in addition and its performance.
