The best description of the ProAccel® triaxial accelerometer is ACCURACY. Scale factor, bias and alignment have all been optimized far beyond the performance of the usual MEMS accelerometer. There is no better triaxial accelerometer for instrumentation, stabilization and control applications.

Features that are standard for the ProAccel® include available ranges up to 10g’s, internal power regulation for power input between 8 volts and 45 volts, EMI and RFI protection, and a case mounted connector.
