Measurement exciters

Brüel & Kjær measurement exciters are designed for vibration testing with force ratings from 10n to 187n. These exciters cover a a wide range of applications; from accelerometer calibration to mobility measurement, or experimental modal analysis on small articles. In all applications our measurement exciters go beyond the accuracy and precision required by industry standards and test houses.
