Description
Overview
GAOTek 4 Channels Vibration Analyzer features a versatile input port that can connect to various types of sensors. It utilizes advanced microelectronics, signal analysis, and fault diagnosis technologies, integrating equipment condition monitoring and fault diagnosis capabilities into a single unit.
It includes the function of four-channel vibration data acquisition, which can complete vibration measurement on-site and automatically store tens of thousands of vibration feature values and spectra of measurement points. It can also display one to four channels of waveforms and spectra synchronously on-site. Additionally, it can serve as an imbalance detector, completing single- and double-sided dynamic balance verification on-site.
