YHZ9 Portable digital vibration meter

Introduction:
The vibrometer is also called a vibrometer vibration analyzer or a vibrometer pen, which is designed by using the piezoelectric effect of quartz crystal and artificial polarized ceramic (PZT). It is widely used in machinery manufacturing, electric power, metallurgical vehicles and other fields.

To modernize equipment management, factories should actively promote advanced equipment management methods and adopt equipment maintenance technology based on equipment condition monitoring. Equipment condition monitoring and fault diagnosis technology is the prerequisite for preventive maintenance of equipment. Especially in heavy industry enterprises, which have strong work continuity and high safety and reliability requirements, they have passed condition monitoring.

Principle of vibration measurement in this section:
The vibrometer is also called a vibrometer vibration analyzer or a vibrometer pen, which is designed by using the piezoelectric effect of quartz crystal and artificial polarized ceramic (PZT). When quartz crystals or artificially polarized ceramics are subjected to mechanical stress, electrical charges are generated on the surface. The piezoelectric acceleration sensor is used to convert the vibration signal into an electrical signal. Through the processing and analysis of the input signal, the acceleration, velocity and displacement value of the vibration are displayed, and the corresponding measurement value can be printed out by a printer. The technical performance of this instrument conforms to the requirements of the international standard ISO2954 and the Chinese national standard GB/T13824, for the vibration intensity measuring instrument, the sine excitation method vibration standard. It is widely used in machinery manufacturing, electric power, metallurgical vehicles and other fields.
