Schrader (Electronics) originally developed Tire Pressure Monitoring System (TPMS) technology in the early 1990s. From the original TPMS sensors built into aluminum clamp-in valves, to today?s patented and programmable sensors and rubber snap-in valves, Schrader has established itself as the global market leader by providing easy-to-use TPMS technology for OEMs as well as the service and repair community. In fact, over 54% of global vehicle platforms carry Schrader TPMS technology off the assembly line, with over 160 million Schrader sensors on the road today.
The battery-powered TPMS sensor monitors a vehicle?s tire pressure, whether the vehicle is stationary or in motion. The sensor is attached to the vehicle?s tire valve stem, with the sensing electronics inside the tire. The sensor periodically measures tire pressure and temperature and transmits this information to an on-board receiver via radio frequency (RF) technology. The receiver decodes the RF signals, and alerts the driver if any of the vehicle?s tire pressures drop below a pre-programmed threshold.
