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.

Type 4808

Permanent Magnet Vibration Exciter
A compact exciter with force ratings up to 187 N (42 lbf) used for long-duration, high g-force testing of relatively heavy loads as well as for accelerometer calibration and mechanical mobility measurements.
Type 4809

Portable Shaker / Vibration Exciter
Portable shaker (or exciter) capable of delivering peak sine forces up to 60 N (13.5 lbf). The ideal solution for vibration testing of small articles and for experimental modal analysis in the field.
Type 4810

Mini-shaker
A compact and lightweight electrodynamic exciter with force ratings of up to 10 N (2.25 lbf). Type 4810 is used for vibration testing of very small articles, for experimental modal analysis with low forces and for mechanical impedance and mobility measurements.
