4. Working Principle
Relying on high-precision DSP digital processing and independent hardware protection architecture, the Vibro-Meter MPC4 200-510-078-115 implements a closed-loop monitoring and protection workflow: sensor signal acquisition → signal conditioning & filtering → parameter calculation & analysis → condition judgment & alarming → interlock protection output → data traceability.
After power-on initialization, the card performs hardware self-test, channel verification and sensor loop detection. It enters normal monitoring mode only after confirming healthy status of the module, channels and sensing loops.
During operation, the 4 dynamic channels and 2 tacho channels synchronously collect various sensor signals from the unit. Optimized filter circuits and DSP algorithms conduct noise reduction, waveform shaping and calibration to accurately compute core operating parameters such as vibration, displacement, rotational speed and phase, as well as advanced diagnostic data including shaft orbit and peak values.
When potential faults such as excessive vibration, shaft misalignment, abnormal speed or equipment looseness occur, the module executes graded responses: minor violations trigger local LED alarms and background event logging; severe violations drive relay interlock signals to initiate unit alert, load reduction or emergency shutdown, preventing severe accidents including shaft abrasion, equipment damage and turbine overspeed.Even if system communication or rack master modules fail, the card maintains independent protection logic to secure unit operation. Meanwhile, operating data and fault timestamps are recorded throughout the runtime to provide accurate evidence for fault analysis, condition assessment and predictive maintenance.
