摘要
本文介绍了仪器的原理、特点及技术性能,它主要用于测量大型旋转机械及工程结构等低频振动的位移值。该仪器不仅能够测量振动的时程曲线,而且还具有峰值保持功能,可直接显示出测点的峰-峰位移值。
The principle and technological features of the ZF-31 vibration amplitude apparatus are introduced in this paper. It is mainly used to measure the displacements of large rotary machines and the vibration of low-frequency engineering structures. The apparatus measures the vibration time-history, possesses the peak-value-holding function and displays the peak-peak values directly.
