3500/61 133819-02 | Seismic Monitoring Module

Industrial Machinery Protection Systems

Main Features and Benefits

The BENTLY 3500/61 seismic monitor delivers critical machinery protection for vibration-sensitive assets with its advanced four-channel architecture. Engineered for industrial environments, it provides continuous structural monitoring with patented dynamic signal processing that eliminates false alarms while detecting genuine seismic threats. Each channel independently processes velocity signals with 24-bit resolution, enabling precise detection of abnormal vibration patterns before they escalate into catastrophic failures.

System protection capabilities include:

• Dual-threshold alarming: Independent Danger and Alert settings for each channel with configurable time delays
• Intelligent signal validation: Continuous verification of sensor integrity and signal path functionality
• Dynamic signal processing: Frequency-selective monitoring with ISO 10816 compliance standards

The 3500/61 module integrates seamlessly into existing 3500 series racks, offering hot-swappable replacement without system shutdown. Its robust design withstands extreme environmental conditions while providing comprehensive diagnostic capabilities through the 3500/20 display interface. Real-time spectral analysis enables early detection of developing mechanical issues, providing maintenance teams with actionable insights to prevent unscheduled downtime.
