Brake Temperature Monitoring

The RACELOGIC Brake Temperature Monitoring System measures, logs and displays the surface temperature of the brake disc, providing invaluable information to the test driver whilst on track.

  • Up to 16 temperature points per sensor
  • Surface temperatures ranging from -20 °C to 1100 °C
  • Compatible with VBOX Video HD2 and VBOX Touch
  • Live temperature display with VBOX Touch


Each of the four 60° FOV sensors can measure up to 16 temperature points on an object with surface temperatures ranging from -20° C to 1100° C.

Live display

When used with the VBOX Touch and the Brake Temperature Monitoring app, you can see the 64 individual heat maps live on screen, as well as live temperature and maximum temperature values.

Compatible with VBOX Video

The sensors can also be connected to a VBOX Video HD2 and the heat maps overlaid in real-time on the video. This shows you exactly what is happening on track and makes it easy to interpret the data.

The brake sensors are designed to measure the rapidly changing temperature on the surface of a brake rotor at various points. This allows for tracking how the temperature spreads over the rotor's surface over time. Such information is crucial for several purposes: it helps in assessing and improving how evenly the brake pads press against the rotor, choosing the right brake pads, ensuring effective cooling, enhancing overall braking performance, and preventing the development of hot spots caused by uneven heating, which can lead to thermal instability.

A sensor is designed to measure temperatures at multiple points — 16, 8, or 4 points — and can do so with a high level of detail, up to 100 times per second (100 Hz). It's capable of measuring temperatures ranging from very cold (-20˚C) to extremely hot (1100˚C). Additionally, all of these sensors are housed in a durable, compact case made of aluminium that is rated IP66, meaning it's well-protected against dust and water.

When bundled with the VBOX Touch data logger (RLVBBTMS), you can record and observe the temperature of all four brake disks on a 4.3-inch colour screen that's easily readable in daylight. The brake temperature monitoring app running on VBOX Touch provides a heat map for each sensor, along with real-time temperature readings, peak temperature values, Speed and Vmax.

You can also use the Brake Temperature Sensor Kit (RLACS314) with a VBOX Video HD2 data logger. In this case, the recorded temperature data is synchronised with the video and can be displayed as a real-time graphic overlay on the video footage.
