Is it better to install internal or external tire pressure monitoring?
2 Answers
Tire pressure monitoring devices are better when installed internally, and the detection effect is also excellent. Below is the relevant information: 1. The role of tire pressure monitoring: The function of tire pressure monitoring is to automatically and continuously monitor the tire pressure during vehicle operation, and to alert the driver in case of tire leaks or low pressure to ensure driving safety. 2. External sensors: The principle involves using a pin to push open the valve core, where the pressure impact received by the sensor reflects the internal tire pressure. The sensor cleverly utilizes the thread of the dust cap for fixation on the valve stem. 3. Internal sensors: These are installed inside the tire, replacing the original valve with one that includes a sensor. The external part is minimal and does not protrude beyond the wheel hub; once installed, it is essentially a permanent solution.
I've driven trucks for twenty years and tried both types of tire pressure monitoring systems. The internal ones require removing the tire to install on the valve stem, costing about 200 yuan more in labor than external ones, but you don't have to worry about theft. For long-haul cargo transport, internal sensors provide accurate readings - even at -10°C in snow, the error margin is just 0.1 bar. External ones simply screw onto the valve stem, but last year at a service area, two got stolen. The key advantage is internal sensors provide real-time monitoring - three minutes before my last tire blowout, the alarm went off, allowing me to pull over and save a truckload of cargo. For frequent long-distance drivers, internal sensors are absolutely worth installing.
