An Miao 3D Three-axis Vibration Meter AV-160D is a portable digital display 3D three-axis vibrating meter. The sensor used is a three-axis piezoelectric vibration sensor, which has X, Y, Z axes or three axes, and can measure three axes at the same time. Vibration parameters or vibration parameters for a single axis. The 3D three-axis vibratIon Meter AV-160D has the function of bearing condition measurement, which conforms to the international standard ISO2954, and is used to test various mechanical vibrations. The measurement accuracy is ±5%+2 characters.
* Auto power off function.
* Lightweight and easy to operate, easy to use.
* Wide frequency range, up to 10-10KHz.
* With AC signal output, it is convenient for auscultation and recording.
* It has bearing condition measurement function.
* Comply with international standard ISO2954, GB13823.3, for periodical motion measurement to detect unbalance 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.
* Three piezoelectric accelerometers with high performance are selected to realize three-dimensional vibration measurement with high accuracy and good repeatability.
* Liquid crystal LCD display, one display can display three vibration parameters (velocity, acceleration and displacement) of one-dimensional vibration at the same time, and can also display a selected parameter of three-dimensional vibration at the same time.
* Optional earphones can be used as a stethoscope.
*Using optional RS232 software and cable, it can communicate with PC computer to realize functions such as printing and statistics.

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.
