Dual-channel Spectrum analyzer
RH802 Dual channel vibration analyzer technical parameter
Features
l 3.5 inches TFT large LCD screen, simple flow chart, compact and light weight, more convenient operation.
l 1GB large storage capacity, can meet high-capacity data collection requirement.
l Wide analysis frequency (0~40KHz), high spectrum resolution ratio, can meet the requirement for precise and complex equipment (high-speed gear) analysis.
l Very flexible parameters configuration including high and low band pass filter, sampling length and sampling frequency etc. Can meet the requirement of data acquisition for various equipments.
l Route or off route data acquisition are allowable, off route data acquired can be saved by sequence number or by measuring point number.
l 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.Main technical parameters
