01 - TTMS Introduction


The RACELOGIC Tyre Temperature Monitoring System (TTMS) is specifically designed to measure, log, and display the surface temperature of a tyre, providing invaluable information to the driver on the track. 

The system consists of RLACS272 tyre temperature sensors that are specifically designed to be used with the VBOX Touch display. You can use this system to measure the highly transient surface temperature of a tyre. The VBOX Touch has a real-time display of the temperature across the width of each tyre and the driver has immediate insight into what is happening to their tyres on the track. This will give you invaluable information for chassis tuning and driver development and for setting the optimum brake bias and tyre setup before a race. The responsive colour display gives you a visual representation via 64 individual heat maps per tyre, as well as live and maximum temperature values, current speed and VMAX.

Each sensor has a field of view of 120° and can measure up to 16 temperature points on an object, with surface temperatures ranging from -20°C to 300°C. The heat blocks on the display represent live tyre temperatures.

You can find the complete technical data for the Tyre Temperature Monitoring System on the datasheet, which is available on the VBOX Motorsport website.
