Technical Specifications 24VDC power supply, multi-channel vibration sensor input. Operating temperature: -40℃ ~ +70℃, built-in signal conditioning and band-pass filtering circuits.
Functional Features Vibration signal conditioning, amplitude calculation, frequency spectrum monitoring, vibration threshold comparison, fault alarm and interlock output.
Application Scenarios Gas turbine bearing vibration protection, steam turbine rotor vibration monitoring, diesel engine vibration condition monitoring.
Performance Parameters High signal resolution, wide vibration frequency range, strong anti-interference capability under mechanical vibration environment.
Structural Characteristics Rack pluggable module, independent LED status indicator for each vibration channel.
Working Principle The vibration sensor outputs weak dynamic signals to this module. After filtering and amplification, the circuit calculates vibration displacement or velocity value, then sends measurement data to the main controller for threshold judgment and protection action.
Installation Requirements Use dedicated shielded coaxial cables for vibration probes, separate vibration wiring from power and inverter cables.
Usage Notes Check probe gap regularly, set alarm and trip thresholds strictly in accordance with machinery operation manual.
