Force and Motion

Use of force and motion sensors enables you to quantify the dynamic characteristics of your vehicle. Measuring acceleration forces can assist in determining where and how to improve your vehicle.

MoTeC supplies the following types:

G-force sensors
Yaw rate sensors
Strain gauge sensors

Strain gauge amplifier

Gear force sensor

G-Force Sensors

These sensors are used to measure vehicle acceleration, i.e.: acceleration, braking and cornering force, which are also used for drawing track maps. 4G (+/–) sensors have a measuring range adequate for normal vehicle behaviour. Peak values in accidents require larger ranges. The signals from a G-force sensor are normally filtered to reduce high frequency noise on the readings, resulting in more accurate vehicle G-forces. That way we are measuring actual forces on the vehicle and not vibration or engine noise.

Yaw Rate Sensor

These sensors measure angular velocity and are used to determine a car's cornering sliding speed. They are normally mounted at both ends of a car in combination G-force sensors, to determine if a car is understeering or oversteering and when it starts sliding.

Strain Gauge Sensors

These sensors are used for measuring the forces through various parts of a vehicle. This can include wing, shocks, brake pedal and steering. The signals from strain gauges are usually very small and need to be amplified with a strain gauge amplifier. Some strain gauges provide an amplified signal that can be wired directly into a data logger.
