Where is the Tire Pressure Monitoring Sensor Installed?

[McCayden]

Tire pressure monitoring sensor installation locations: Built-in sensors are installed inside the tire, which is relatively stable and provides more accurate temperature monitoring data; External types are sensors added outside the valve stem, which are more convenient to install. Direct tire pressure monitoring systems use pressure sensors installed in each tire to directly measure the tire pressure, transmitting the pressure information from inside the tire to a central receiver module via a wireless transmitter, then displaying the tire pressure data for each tire. The system automatically alerts when the tire pressure is too low or there is a leak. The working principle of indirect tire pressure monitoring is: when the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels; by comparing the differences in rotation speeds between tires, the purpose of monitoring tire pressure is achieved.
