Handheld Dual Channel Portable Vibration Analyzer Balancer HG904 Data Collector

HG904 Dual Channel Data Collector Portable Vibration Analyzer Balancer


Imbalance is one of the main causes of machine vibration. It is estimated that about 50 percent of all the faults are caused by imbalance of rotors. The best mean for getting rid of mechanical imbalance is on-site balancing. HG904 Machinery Analyzer/Balancer is especially useful for this purpose. It can measure the intensity of the vibration; diagnose vibration cause by analyzing the frequency spectrum. It can also be used to measure the rotation speed and vibration phase, and to calculate the imbalance weight and location.

Features:

• Easy to use
• Vector illustration, the balancing process and result are shown clearly at a glance
• Storage of 10 rotors balancing data
• Selectable of trial mass remove or remain
• Decompose of balancing result to two assigned location
• Trial weight range calculated according to the weight of rotor, rotation speed, radius and required balance grade
• Trial mass validity judged automatically
• Measuring RPM, amplitude and phase
• On-site 400 lines FFT spectrum and diagnosis function
• Dual-channel simultaneous data collection
• Hardware envelop demodulation for bearing and gear diagnosis
• Transfer function for measuring natural frequency
• Waveform and spectrum display by large LCD
• Storage of vibration values and vibration waveform
