Advanced Triaxial Accelerometer for Race Car Performance Enhancement

Motorsports recognizes the need for a triaxial accelerometer that can provide accurate vibration results in pre-race trials, and real-time measurements during the course of an actual race. Precise data needs to be gathered that allows the racing engineer to determine design modifications and suspension adjustments when fractions of a second can determine the winner. Measurement Specialties, Inc. has developed the Model 4203 accelerometer that satisfies these requirements. The accelerometer features a silicon sensor element utilizing silicon MEMS technology (Micro Electro Mechanical Systems) packaged in a lightweight metal housing. DC capability allows the capture of long duration transients in order to measure whole body motion. On-board signal conditioning outputs high level, low impedance signals. Each of the full scale g-ranges of the three orthogonal axes can be independently selected for optimum measurement resolution.
