Description
Overview
GAOTek Low frequency Acceleration Velocity Instrument is the pocket style vibrometer is mainly used in the general case of mechanical vibration measurement. Particularly suitable for equipment condition monitoring. Various mechanical vibration of the vibration source from the structural design, manufacturing, installation, commissioning and the environment itself. The presence of vibration is bound to cause structural fatigue damage, failure of parts wear and impact damage. For low-frequency vibration, the main consideration should be given to the fatigue strength of the destructive nature of the displacement damage; For 1KHz more high-frequency vibration, should primarily consider the impact and resonance destruction. The theoretical proof fatigue and is proportional to the vibration velocity of the vibration member, the vibration energy generated by the vibration velocity is proportional to the square of the result of energy transfer to cause wear and other defects. Accordingly, in the vibration criteria, whether from fatigue damage or wear defects such speed standard most suitable. By measuring the speed of the rotating machinery vibration, and vibration intensity criterion (10Hz to 1kHz)-ISO2372 standard compared to the running state of the equipment can be traced.
