4-Channel Vibration Analyzer HG-904A4 with Multi-Sensor Input Ports
The HUATEC HG-904A4 multi-functional instrument 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.
The analyzer includes four-channel vibration data acquisition, enabling on-site vibration measurement with automatic storage of tens of thousands of vibration feature values and spectra. It can display one to four channels of waveforms and spectra synchronously on-site and serves as an imbalance detector for single- and double-sided dynamic balance verification.
