Strain Gauge Load Sensors

How can we measure the force in a component of our car chassis or suspension?

Introduction

A load cells is generically defined as a sensor that can measure load (force). The load sensing can be achieved in some different ways so the use of strain gauges is one of the most common methods.

Any machine, from industrial equipment to a racing vehicle necessitates precise knowledge of the forces and moments affecting its main components. Without this knowledge it is impossible to validate the calculated or simulated design loads.

In a motorsport or safety critical environment such as aerospace, load sensors give vital information on tyres, frame and powertrain that is needed to constantly improve the performance and reliability. Where the regulations do not prohibit its use (typically in the less expensive formulae), strain gauge sensors are used in most racing motorcycles, single-seaters, oval racers, rally cars etc.
