T04Z Automotive-Grade RF433 Adhesive-Mounted Tire Pressure Sensor For Trucks
The T04Z is an automotive-grade, built-in, adhesive-mounted TPMS tire pressure sensor designed for trucks. It uses RF433MHz FSK radio frequency communication and is affixed to the inner liner surface of the tire. This built-in, adhesive-mounted design is suitable for heavy-duty trucks and tractor-trailers.
The product complies with commercial vehicle automotive standards and is engineered for freight operating conditions such as long-distance heavy-load transport, continuous vibration, and alternating high and low temperatures. The sensor updates monitoring data with every rotation of the tire and supports continuous monitoring even when the vehicle is parked.
It collects real-time tire pressure and temperature data and transmits it via a 433 MHz wireless signal to the RF receiver unit, enabling round-the-clock monitoring of commercial vehicle tires. This system provides timely alerts for abnormal tire pressure, effectively preventing tire blowouts during high-speed driving and ensuring the safety of freight vehicles. The product is an aftermarket, non-destructive retrofit solution that requires no valve stem replacement and is easy to install, remove, and maintain.
The complete tire pressure monitoring system is compatible with multi-wheel heavy-duty trucks and tractor-trailer combinations. Centered around the T04Z built-in adhesive tire pressure sensor, the system includes an RF receiver unit, an in-vehicle display terminal, and a main control and warning unit. It can be integrated into the original commercial vehicle chassis without damaging the vehicle's structural integrity. The core components are as follows:
Adhered to the inner liner of the tire, it features a built-in pressure sensing chip, temperature detection module, acceleration wake-up unit, and an RF433MHz FSK radio frequency transmission module. It supports tire rotation sampling and stationary monitoring, collecting real-time tire pressure and temperature data and transmitting it wirelessly. It features a built-in battery with a design life of 5 years and is capable of withstanding high temperatures and continuous intense vibrations inside the tire.
Specifically optimized to address signal shielding caused by long vehicle bodies, multi-axle trailers, and metal frames. Features high-gain signal reception to resist electromagnetic interference from onboard generators and electronic control systems. Supports parallel reception of multiple sensors, enabling data collection from multiple wheel positions on a tractor-trailer combination, thereby reducing data packet loss and latency.
Designed specifically for commercial vehicles, it supports a 24-volt power supply and is compatible with both solar power and the vehicle's electrical system. The screen clearly displays tire pressure, temperature, and sensor battery levels. Adapted to the installation layout of truck cabs, it is equipped with a high-brightness display that ensures clear visibility day and night without obstructing the driver's line of sight.
Responsible for data analysis, threshold determination, fault classification, and audible and visual alerts. It incorporates algorithms specifically designed for commercial vehicles and can adapt to heavy-duty operating conditions such as empty loads, full loads, hill climbing, and sustained braking. It accurately identifies abnormal tire conditions and supports system self-diagnosis and fault logging.
