What is the limitation of Tire Pressure Monitoring Systems that use BASELINE technology?

0

Most other TPMS products compromise a critical aspect of tire pressure monitoring, ease of proper air pressure level maintenance. Ultimately any TPMS system is only as effective as it is usable by the drivers of the vehicle and the maintenance departments. Most removable Valve Cap Sensor based TPMS rely on the existing tire pressure (at the time the sensor is attached) to determine a reference tire pressure, often referred to as its BASELINE. When a Sensor is installed, it records the tire pressure at the time of installation as its BASELINE pressure setting. If you remove and reinstall a Sensor while the tires are warm, the Sensor will record the elevated WARM pressure when reinstalled. This becomes the new BASELINE pressure from which to trigger an alarm. When the tires cool, the pressure could fall enough to cause a false alarm. Obviously this must be done in order to maintain proper tire pressure. Essentially, this defeats the purpose of a tire pressure monitoring system.
