Why vibration is measured in G?
Vibration can be expressed in metric units (m/s2) or units of gravitational constant "g," where 1 g = 9.81 m/s2. An object can vibrate in two ways: free vibration and forced vibration. Forced vibration at or near an object''s natural frequency causes energy inside the structure to build.
Vibratory Feeder: What Is It? How Does It Work? Types Of
Direct Vibratory Feeders: Direct or positive mechanical vibratory feeders use a crank and connecting rod that generate oscillation with a low frequency and high amplitude. Positive conveyors are rarely used due to the high vibration transmitted to the supporting structures.

Amplitude of Vibration The feeder is designed to work at a predetermined maximum amplitude, which must not be exceeded. The maximum amplitude of the feeder can be found marked on the label attached to the side of reaction base. GENERAL CONSTRUCTION OF VIBRATORY FEEDERS
Other resonance type vibratory feeders seek to control both the amplitude and frequency of feeder vibration using single sensor arrangements. One example of such systems is disclosed in U.S. Pat. No. 4,331,263 to Brown, wherein the amplitude and frequency of vibration are sensed by detecting the third harmonic of the drive current signal.
Why is Vibration Amplitude in G?
Vibration motors are not used on their own – they''re attached to a product/device/piece of equipment that is intended to vibrate. Therefore we are interested in the whole system (motor + target mass). We measure the vibration amplitude by mounting the motor on a known target mass and reading the results from an accelerometer, see more here ...
