Pure Copper Base T07W Truck And Bus Automotive-Grade TPMS Sensor

The T07W Truck External RF433 Automotive-Grade Tire Pressure Sensor is an aftermarket, non-invasive tire pressure monitoring and data collection device developed specifically for commercial vehicles such as heavy-duty trucks, tractor-trailers, semi-trailers, and long-distance passenger buses. The product meets commercial vehicle automotive standards and is designed for complex road conditions—including long-distance heavy-load transport, continuous vibrations, significant day-to-night temperature fluctuations, as well as exposure to rain, dust, and impacts from road debris—offering superior performance compared to standard consumer-grade external sensors. It features an external mounting design on the tire valve stem, compatible with the 8V1 truck-specific valve stem, eliminating the need for tire removal or rebalancing, and enabling rapid retrofitting of the entire vehicle.

The sensors are equipped with high-precision MEMS sensor chips that collect real-time tire pressure and temperature data. This data is transmitted wirelessly via 433 MHz FSK radio frequency to the RF receiver unit, providing accurate feedback on the operating status of each tire. This effectively addresses common issues in freight vehicles, such as slow tire deflation, rubber aging caused by high brake temperatures, uneven tire wear under heavy loads, and the risk of tire blowouts during high-speed driving. It is suitable for retrofitting freight fleets, safety upgrades for older vehicles, and compliance-related installations.

The complete monitoring system is compatible with multi-wheel heavy-duty trucks and tractor-trailer combinations. Centered around the T07W external tire pressure sensor, the system includes an RF receiver unit, an in-vehicle display terminal, and a main control and warning unit.
