Standalone TPMS with Real-time Monitoring and 5 Years Battery Life for Universal Tractor and Trailer Compatibility

Product Introduction: Standalone TPMS for Tractor and Trailer

Overview

The Standalone Tire Pressure Monitoring System (TPMS) is developed for tractor-semitrailer combinations. It works locally as a standalone unit without CAN bus integration or cloud server dependency. The system consists of an in-cab monitor, wheel sensors and wireless repeaters, which enables real-time monitoring of tire pressure and temperature for all wheels on tractor and trailer. It supports trailer swap for drop-and-hook transport, ideal for long-haul fleets and heavy-duty semi-trailer operations.

System Composition

1. Cab Monitor: 12/24V powered color LCD display, shows real-time tire pressure & temperature with graphic wheel layout, audible & visual alarm, unit switch (BAR/PSI, ℃/℉), customizable alarm thresholds.
2. Tire Sensors: External or internal sensors with IP67 protection. Measure pressure and temperature and transmit data via RF wireless signal, shock-resistant for heavy-duty application.
3. Wireless Repeater: Mounted on chassis to boost RF signal from trailer rear wheels, ensuring stable long-distance communication.

Key Functions

• Real-time pressure and temperature monitoring for all tractor & trailer tires
• Multi-alarm: low pressure, high pressure, over-temperature, rapid deflation, sensor loss and low battery
• Support trailer swap & quick re-pairing for drop-and-hook operation
• Standalone local operation, no CAN or cloud platform required, easy retrofit
• Wheel position learning after tire rotation, supports multi-axle configurations
• System self-check on power-on

Advantages

1. Standalone design, high compatibility, simple retrofit for new & used semi-trailers.
2. Wireless repeater ensures reliable signal reception for long trailers.
3. Early warning prevents tire blowouts, extends tire service life and reduces fuel & maintenance cost.
4. Rugged hardware with high ingress protection, reliable for rough long-haul road conditions.
5. Easy maintenance, replaceable sensor batteries, low fleet operation cost.

Application

Long-haul tractor + box/van/tank semitrailers, drop-and-hook fleets, heavy-duty semi-trailers, for both OEM pre-installation and aftermarket retrofitting.
