Wireless tire pressure monitoring utilizes high-precision sensors installed in each tire. With the built-in battery as the power source, the tire pressure and temperature are directly measured, and the tire pressure and temperature are monitored and displayed. When the tire pressure and temperature are abnormal, the system will automatically alarm. After the battery is out of power, it will no longer be monitored and emit a detection signal. At this time, the battery should be replaced.
Generally speaking, TPMS sensor is divided into two types: external type and external type.
External tire pressure monitoring sensor: it is directly screwed on the valve, easy to install. It can be installed in 5 minutes. However, in the course of use, the user experience reflects the inconvenience of use. Because every time you inflate the tire, you need to disassemble it, and then screw it up again. The battery power can be used for about 2 years. According to the calculation of 4-5 hours of daily driving, you can buy a battery to replace it when the battery is exhausted.
The built-in sensor needs to be balanced after installation, and the external sensor is not needed.
Characteristics of two tire pressure monitoring sensors
After changing the tire, the built-in sensor needs to do a simple deflation match, while the external sensor needs to be adjusted accordingly.
The built-in sensor has good anti-theft performance and is generally not stolen. The external sensor is slightly less anti-theft and is screwed onto the valve, making it easy to be stolen during use. Therefore, many manufacturers now add anti-theft nuts, which require professional wrenches to remove them, increasing the anti-theft performance.
In terms of measuring the accuracy of the tire pressure monitoring system, since the external and built-in tire pressure monitoring schemes are the same, the accuracy of the tire pressure measurement will not be different. However, the built-in tire pressure monitoring is more accurate for tire temperature measurement. The external ones are slightly affected by the external environment, vibration and temperature. In addition, you need to reset TPMS sensor if necessary.
There are two types of tire pressure monitors on the market, one is a built-in tire pressure monitor, and the other is a tire pressure monitor. The so-called wireless tire pressure monitoring is often referred to as an external tire pressure monitor. The main working principle is to transmit the tire pressure data to the tire pressure monitor through the Bluetooth system. The tire pressure monitor can only work if the battery is discharged, and it also uses solar energy to store electricity. Is wireless tire pressure monitoring safe? As long as the quality and safety of big brands are guaranteed. It is also necessary to install smart TPMS sensor or tire monitor sensor.
There are many car owners who have little knowledge of tire pressure monitors or tire pressure monitoring systems. They just heard about this product. But it has not been actually used, and the function of the tire pressure monitor is not known. Is it necessary for the car to install tire pressure monitoring? The answer is yes. The tire air pressure sensor can monitor the tire pressure of the four tires at any time. Under normal circumstances, the tire pressure of the tire is normal at 2.5-2.5par. If the tire pressure is too high or too low, it is easy to affect the driving of the vehicle, and serious traffic accidents may even occur.
The advantage of wireless tire pressure monitoring is that: the installation is relatively simple, basically you can solve it yourself; the tire pressure sensor cost is not too expensive.
The disadvantage of wireless tire pressure monitoring is that the anti-theft performance is poor, because basically the same brand of disassembly tools are used, which can remove the external sensors of the same brand.
Wireless tire pressure monitoring safety: Whether it is a built-in or external tire pressure monitor, as long as the quality passes the safety, there is no problem. As long as you pay more attention to observation, you can repeat the TPMS sensor if necessary.
