RH802 Dual-channel vibration analyser

The ROZH dual-channel vibration analyser RH802 is developed specifically for the industrial field environment. It has an extensive operational system; the function modules of route plan, off-route plan, dynamic balance, coast up/down and bump test are displayed in less than 10 interfaces. The software is operated on ARM directly. Without the operation system, it runs more stable and avoids a slow boot. Both starting up and shutdown can be finished in one second, which greatly saves user’s time on site.

  • 3.5 inches TFT large LCD screen, simple flow chart, compact and light weight, more convenient for operational use.
  • 1GB large storage capacity and can meet high-capacity data collection requirements.
  • Wide analysis frequency (0~40KHz), high spectrum resolution ratio and can meet the requirement for precise and complex equipment (high-speed gear) analysis.
  • Very flexible parameter configuration including high and low band pass filter, sampling length and sampling frequency etc. Can meet the requirement of data acquisition for various equipment.
  • Route or off route data acquisition are allowable, off route data acquired can be saved by sequence number or by measuring point number.

Comprehensive functions:

  • Acquiring vibration data like velocity, acceleration, displacement:
  • Acquiring RPM; Self-testing function of system acquistion
  • Acquiring single or dual channel waveform, spectrum, overall value and long waveform.
  • Acquiring XPM, cross-power spectrum, phase difference spectrum, and acquiring the phase difference between two measuring points directly.
  • Long time domain waveform, equivalent to digital tape recorder, can capture the machine’s transient process data.
  • Coast up/down testing analysis, to track the vibration varies in starting and stopping.
  • On site dynamic balancing, users can complete dynamic balance test comply with the tips.
  • Overall value, capture the entire changing process for equipment transient vibration, convenient to analyze the changing connecting between machine vibration and technical parameter on site, the interval time can be set as needed.
