01 - BTMS Introduction


The RACELOGIC Brake Temperature Monitoring System (BTMS) has been specifically designed to measure, log and display the surface temperature of the brake disc, providing invaluable information to the test driver whilst on track.

The system consists of RLACS314 brake disc temperature sensors which have been specifically designed for use with a VBOX Touch display to measure the highly transient surface temperature of a brake disc, providing invaluable information for chassis tuning and driver development. The display offers a real-time display of the temperature across the width of each brake disc. This provides drivers with an immediate insight into what is happening to their brakes on track; invaluable information to evaluate and optimise the pad pressure distribution, pad selection, cooling efficiency, braking efficiency and hot spot formation from thermoelastic instabilities. The responsive, colour display offers a visual representation via 64 individual heat maps, as well as live and maximum temperature values.

Each sensor has a field of view of 60° and can measure up to 16 temperature points on an object with surface temperatures ranging from -20°C to 950°C. Heat Maps on the display represents live brake disc temperatures.

For further information, the Brake Temperature Monitoring System datasheet is available on the VBOX Automotive website.
