Measurement exciters – Brüel & Kjær Sound & Vibration

Type 4809

Vibration Exciter
A small exciter capable of delivering peak sine forces up to 60 N (13.5 lbf). Used for vibration testing of small articles and for experimental modal analysis.
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.
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.
