Acceleration Pickup Frequently Asked Questions

When measuring the acceleration of lightweight objects, the weight of the acceleration pickup may affect the measurement.

The inherent frequency of an object can be simply expressed by the following formula.

(Hz) m: mass k: spring constant

Therefore, by attaching the acceleration pickup to the measurement target, the value of 'm' becomes heavier by the weight of the acceleration pickup, which affects the frequency characteristics.

The weight of the acceleration pickup must be less than 1/100 of the weight of the object being measured, or at least less than a few tenths.

In cases where the weight of the acceleration pickup becomes a problem, non-contact measurement methods such as the LV series Laser Doppler Vibrometer are effective.
