Feedback Vibrometer
A seismic-type vibration pickup is described having its natural frequency in the middle of the operating range; the response is made flat by means of electromechanical feedback. Advantages over conventional velocity pickups are ruggedness and stability. A typical instrument covers 5–1000 cps within...

| Zusammenfassung: | A seismic-type vibration pickup is described having its natural frequency in the middle of the operating range; the response is made flat by means of electromechanical feedback. Advantages over conventional velocity pickups are ruggedness and stability. A typical instrument covers 5–1000 cps within ±10%. Output is proportional to acceleration. |
