Functional Features Real-time calculation of rotating shaft speed from sensor pulse signals. Independent configurable alarm and trip thresholds for overspeed and underspeed. Zero-speed detection function monitors shaft stop status. Built-in sensor loop fault detection identifies wire break and short circuit. Front panel LED indicators show speed status, alarm and trip states. Uploads speed data and fault information to main processing module.
Application Scenarios Installed in machinery protection racks of steam turbines, centrifugal compressors, large fans and heavy-duty pumps in power plants and petrochemical refineries. Used for shaft speed monitoring and overspeed protection.
Performance Parameters
- High speed measurement accuracy
- Fast overspeed trip response speed
- Stable pulse signal acquisition under vibration environment
- Continuous sensor cable health monitoring
Material Composition High precision industrial PCB with pulse signal conditioning and counting chips. Metal shielding shell blocks external electromagnetic noise. Gold plated backplane connector ensures stable signal transmission. Flame retardant plastic front panel with status indicator windows.
Structural Characteristics Standard rack mount plug-in card for machinery protection rack slots. Front panel is equipped with wiring terminals for speed sensor and LED indicators. Mechanical lock structure fixes the module firmly against vibration displacement. Internal metal shielding covers pulse signal acquisition circuit.
Working Principle Pulse signals generated by magnetic pickup speed sensor enter the module through front terminals. Signal conditioning circuit filters and shapes pulse signals. Internal counter calculates real-time rotating speed according to pulse frequency. The module compares measured speed with preset overspeed, underspeed and zero-speed thresholds. When speed exceeds threshold, alarm or trip signal is sent to rack bus. The module continuously checks sensor cable integrity and reports loop faults.
Installation Requirements Install the module inside dedicated machinery protection rack. Speed sensor signal cables must be routed separately from high power inverter cables. Sensor cable shielding applies single-end grounding method following system manual. Ensure cabinet cooling ventilation works normally.
Use Precautions Complete sensor calibration and threshold setting before commissioning and putting machinery-protection system online. Do not arbitrarily modify overspeed trip threshold parameters during equipment running. Carry out regular inspection for sensor cable insulation integrity. Replace module once permanent hardware fault appears in self-diagnosis report.
