RT-Split

Wheel mounted IMU for accurate slip measurements

Able to capture wheel motion in every axis, the RT-Split is a powerful and reliable measurement system for direct tyre slip angle measurement.

where can i buy this

OVERVIEW

Wheel mounted IMU works in all conditions

Mounting the IMU on the wheel provides a very high slip angle precision of 0.15° at 50 km/h. The small, light weight, wheel-mounted sensor is IP65 certified and designed to work in wet or dusty conditions found next to a moving wheel. The RT-Split gives accurate results even on wet, or loose surfaces that can cause optical solutions to give inaccurate results.

Precise measurements

Measure wheel acceleration to ±30 g and angular rate to ±300°/s.
Measure position with up to 1 cm precision.
Measure in three axes at 100 Hz.

Display in real time and capture permanent logs

Ethernet and CAN bus interface allow measurements to be output in real-time as well as logged internally.
Capture data from external sources in the same file for easy synchronisation.

Fully integrates with the testing system

The RT-Split includes CAN bus inputs/outputs and ABD robot interface to full integrate with third party devices.

An RT-Split for all requirements

The RT-Split is available in three flavours to meet differing precision needs.
