External Screw Caps CAN Tyre Pressure Monitoring System

The External Screw Cap CAN Tyre Pressure Monitoring System is designed for motorsport and track use, allowing real-time tyre pressure and temperature data to be sent directly to your vehicle’s data system via CAN.

The system monitors both tyre pressure and tyre temperature, helping drivers and teams set alarms for low or high pressure, see when target operating pressures have been reached, predict hot and cold pressure requirements, and analyse tyre performance on track.

Unlike pit lane pressure checks, this system allows tyre data to be viewed and logged while the car is running, giving a more accurate picture of tyre behaviour during real driving conditions.

Key Features

CAN-Based TPMS System
Outputs tyre pressure and temperature data via CAN for use with Ecumaster ADU displays or other compatible CAN-based data systems.

Real-Time Tyre Monitoring
Displays and logs pressure and temperature data for all four tyres, helping improve setup, consistency, and tyre management.

Track-Focused Data
Allows you to monitor operating pressures on track, review tyre performance, and make more informed setup decisions.

Pressure Alarm Support
Set alarms for low or high tyre pressures when used with a compatible display or data system.

External Screw Cap Sensors
External sensors screw onto standard valve stems for straightforward installation.

Fast Transmission Rate
This system has a faster transmission rate than road-based TPMS systems, with data transmitted approximately every 1 second.

Compatible with CAN Data Systems
This is a CAN output only system and can be used with any display, logger, or data system that accepts CAN inputs and has an available CAN input.

Sensor Information

The external sensors require CR1632 batteries and screw onto standard valve stems.
