3500/42M (176449-02T) Seismic Monitor Instructions
The 3500/42M earthquake monitor is a dedicated monitoring module in the Bently Nevada 3500 mechanical protection system, mainly used for continuous monitoring of low-frequency vibration and seismic acceleration signals of equipment or structures, with a focus on destructive vibration events for large rotating machinery and critical infrastructure.
This module is not used for conventional shaft or shell vibration monitoring, but specifically for analyzing and protecting against earthquakes, strong low-frequency vibrations, or structural responses.
Core role positioning
Monitor the impact of earthquakes or strong low-frequency vibrations on equipment
Provide structural safety protection basis for critical equipment
Trigger alarm or interlock when abnormal vibration occurs
Provide event records and trend data for operators
Functional Characteristics Description
Support low-frequency vibration/acceleration signal acquisition
Signal processing methods optimized for earthquake characteristics
Continuous monitoring and comparison of vibration amplitude
Support alarm threshold and danger setting
Can work in conjunction with other modules of the 3500 system
Provide event capture and historical data recording capabilities
Helps distinguish between normal operating vibrations and abnormal impacts
The module runs stably and is suitable for long-term online monitoring
System integration characteristics
Installed in a 3500 rack and managed in conjunction with the monitoring system
Communicate with display, recording, and protection modules through the system bus
Can participate in system level alarm, interlock or shutdown logic
Suitable for inclusion in high reliability mechanical protection architecture
Typical application scenarios
Monitoring of generator sets and their basic structures
Large rotating equipment such as steam turbines and compressors
Key industrial facilities in earthquake prone areas
Energy and chemical projects with extremely high requirements for structural safety
