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.

1. Tire pressure and temperature monitoring data are updated with every rotation of the tire, dynamically capturing real-time tire conditions.
2. Parked Vehicle Monitoring: While the vehicle is stationary and the engine is off, the system continuously monitors tire pressure to identify potential slow air leaks.
3. Collects raw sensor data on tire pressure and temperature in real time.
4. Transmits monitoring data via 433 MHz FSK wireless communication.
5. Supports pairing with an RF receiver unit to enable long-distance signal relay transmission.
6. Outputs raw monitoring data to enable the receiver unit to detect anomalies and identify faults.

1. Built-in adhesive mounting: The sensor is affixed to the inner wall of the tire, requiring no modifications to the rim or valve stem, making it ideal for quick retrofitting on existing trucks. The sensor is concealed inside the tire, protected from external impacts by gravel and resistant to tampering.
2. Monitoring data is refreshed with every tire rotation, providing dynamic insight into tire operating conditions. Supports parking monitoring, providing continuous monitoring while the vehicle is parked to detect potential slow leaks early.
3. Automotive-grade wide-temperature design ensures stable operation from -40 to 125°C, adapting to the extreme temperature differences encountered during long-distance transport across northern and southern regions.
4. Pressure measurement accuracy of 0.1 bar ensures high monitoring sensitivity, capturing even minor tire pressure changes to provide early warnings of potential hazards.
5. The RF433 MHz radio frequency signal offers strong penetration, making it suitable for long-body, multi-axle semi-trailer trucks. It resists shielding from metal frames and ensures stable signal transmission.
6. Designed for a 5-year service life, meeting the medium- to long-term needs of fleets while effectively controlling sensor replacement and maintenance costs.
7. Flexible installation options are not restricted by rim structure or valve stem specifications, making it compatible with various tire retrofit types.
