An Miao AV-160A Vibration Meter is used to measure periodic motion to detect the imbalance and deviation of moving machinery. AV-160A Vibration Meter is specially designed for on-site measurement of various mechanical vibrations in order to provide data for quality control, running time and prior equipment maintenance. The AV-160A Vibration Meter uses a high-performance accelerometer to achieve accurate and reproducible measurements.
* With bearing condition measurement function.
* AV-160A Vibration Meter has AC signal output, which is convenient for auscultation and recording.
* Wide frequency range, in the acceleration mode, the frequency can reach 10-10KHz.
* Use piezoelectric acceleration sensor to convert into vibration signal.
* AV-160A Vibration Meter can be equipped with earphones to be used as a stethoscope.
* Use USB data line output to communicate with PC.
* Provide Bluetooth data output option.
* Conforms to international standard ISO2954 for periodic motion measurement to detect imbalance and deviation of moving machinery.
* Designed for on-site measurement of various mechanical vibrations to provide data for quality control, running time and prior equipment maintenance.

Note: (1) Class I is a small motor (motor less than 15kw, etc.); Class II is a medium-sized machine (motor 15kw~75kw, etc.); Class III is a large prime mover (hard foundation); Class IV is a large prime mover ( Elastic base)
(2) A / B / C / D are vibration levels; A is good, B is satisfactory, C is not satisfactory, and D is not allowed. The measured speed (RMS) values shall be in three orthogonal directions of the bearing housing.
