Technical Specifications Input Channel: 4 vibration signal input channels Signal Type: Piezoelectric accelerometer signal Power Supply: Powered by rack backplane Operating Temperature:0℃ ~ +60℃ Mounting: 3500 rack slot mounting Housing: Metal rack card casing
Functional Features 4 independent signal input channels for casing vibration measurement. Support piezoelectric accelerometer signal acquisition. Real-time vibration value calculation and alarm/trip threshold comparison. Built-in transducer fault detection function. Hot swappable for online maintenance. LED indicators for channel status and alarm.
Application Scenarios Bearing housing absolute vibration monitoring for turbine and gas turbine. Casing vibration measurement of centrifugal compressor, large fan and pump. Power generation unit rotating equipment condition monitoring rack. Oil and gas plant critical machinery protection system. General industrial heavy rotating equipment casing vibration supervision.
Performance Parameters Measurement precision: High accuracy vibration signal sampling Fault detection: Detect transducer open circuit and short circuit Data output: Upload vibration value and alarm status to rack interface module
Structural Characteristics Standard rack card metal casing. Internal signal conditioning, sampling and processing circuit. Backplane connector for power supply and data communication. Front panel signal input terminals and channel status LED indicators. Front panel locking structure.
Working Principle Vibration signal from accelerometer is sent to module input terminals. Internal circuit conditions and samples the vibration signal, calculates vibration amplitude and frequency parameters. The module compares measured value with preset alarm and trip thresholds, generates alarm logic signal, and uploads all measurement data and status to rack interface module.
Installation Requirements Insert module into specified slot of 3500 rack and lock front panel. Ensure backplane connector fully contacts rack backplane. Connect accelerometer shielded signal cable to front input terminals. Set measurement unit, threshold and transducer parameters by configuration software. Check channel status indicators after power on.
