Before and after buying a tire pressure monitoring product, you need to ask yourself three questions: buy internal or external, what is the use of the tire pressure monitoring product and tire pressure sensor you bought, and how to judge the product you have already purchased. Let us look at these issues together.
This problem is an old question for choosing tire pressure monitoring products. First of all, to eliminate everyone's biggest concerns, built-in tire pressure monitoring and external tire pressure monitoring are essentially the same generation of products, are direct tire pressure monitoring, the accuracy is relatively high, as long as the quality can meet daily use.
There is indeed a difference in the monitoring accuracy between the two. In theory, the error range of the built-in tire pressure monitoring is smaller, and the tire temperature value of the built-in tire pressure monitoring is more accurate. However, this difference is within the same level. For tire pressure monitoring products, the same level means that the built-in tire pressure monitoring can warn of abnormal tire pressure, and the external tire pressure monitoring can also be done. However, the error of the external tire pressure monitoring product is slightly higher by 0.1-0.2bar, so the response speed and sensitivity may be slightly delayed. After our actual measurement, we found that this delay is basically imperceptible, both numerically and experimentally.
The price will influence the behavior of the public to choose tire pressure monitoring products. External tire pressure monitoring products can also be sold for thousands, and internal tire pressure monitoring products are also available for about 500 yuan. It can be seen from this that the price should not be our core consideration for driving safety. Choose the products with good quality, good workmanship and mature technology within the scope of your ability. More importantly, after buying back, you should carefully experience and test. The problem is enough to prove that the product quality control is not good, and other products should be purchased for replacement.
Tire pressure monitoring products monitor the value and change trend of tire pressure, and the corresponding tire temperature. What is the use of monitoring these? If the tire pressure is abnormal, the most extreme case is a flat tire, which can easily cause the car to roll over and even cause serious traffic accidents. Insignificant changes in tire pressure may also increase fuel consumption and vehicle wear, and ultimately increase your fuel money and reduce the life of the car.
Under normal circumstances, the tire pressure monitoring display will show the tire pressure value and tire temperature value of each wheel. Abnormal values will remind you by constantly flashing. The values here are generally real-time values. When the tire pressure is abnormal, not only the screen flashes but also a buzzer or voice is emitted. When your tire pressure value exceeds the normal range, the tire pressure monitoring display will beep or voice. At this time, it is best to slow down and check whether the corresponding tire has a problem.
