Product Performance

The module adopts 4-channel parallel acquisition technology, with a data sampling rate of 10kHz per channel, vibration measurement accuracy ±0.1% FS, and axial position measurement accuracy ±0.02mm, which can capture small parameter changes during equipment operation. It integrates a digital filtering algorithm, supporting an adjustable filtering frequency band of 5Hz-1kHz, effectively filtering out electromagnetic noise and mechanical interference signals in industrial sites.

Equipped with online self-test function, it real-time monitors channel acquisition circuits, sensor connection status and module power supply, with fault diagnosis coverage ≥99%. Fault information is uploaded to the controller in real time via the frame bus, supporting “first-out fault” recording for easy fault tracing. It supports multi-level alarm threshold setting (alarm/trip), threshold configuration is completed via 3500 configuration software, and alarm response time ≤100ms.

Fully compatible with Bently Nevada 3500/05 frame controller and 3500/22M display module, it supports data storage, trend analysis and report generation via System 1® equipment health management software. The mean time between failures (MTBF) is ≥500,000 hours, meeting the 24/7 continuous monitoring needs of rotating machinery.
