BENTLY 3500/42-01-00 high-performance vibration monitoring module

BENTLY 3500/42-01-00 is a high-performance vibration monitoring module developed by Bently Nevada (now part of GE Vernova), serving as a core component of the 3500 Series Rotating Machinery Monitoring System. It is specifically designed to collect, process, and analyze vibration signals from eddy current sensors (e.g., Bently 3300 Series) or accelerometers, providing real-time monitoring of rotating machinery (such as turbines, generators, compressors, and pumps) and triggering alarms or interlocks for abnormal conditions. This module is critical for preventing equipment failure, reducing unplanned downtime, and ensuring industrial process safety. Below is its comprehensive detailed information:

I. Core Technical Parameters

Category	Specific Specifications
Applicable System	Bently Nevada 3500 Series Rotating Machinery Monitoring System; compatible with 3500/10 (single-frame) and 3500/20 (multi-frame) system frames
Model Decoding	- 3500/42: Base model (vibration monitoring module)- 01: Channel configuration (2 independent monitoring channels)- 00: Optional features (standard version, no additional extended functions)
Input Compatibility	- Primary input: Differential eddy current sensor signals (from Bently 3300/3500 Series probes, 0-5V peak-to-peak)- Secondary input: Single-ended accelerometer signals (4-20mA current or 0-10V voltage)- Input impedance: ≥10MΩ (for eddy current signals); ≤100Ω (for current signals)
Measurement Capabilities	- Vibration parameters: Shaft relative vibration (displacement, μm), bearing housing absolute vibration (velocity, mm/s; acceleration, g)- Measurement range: 0-2000μm (displacement), 0-50mm/s (velocity), 0-10g (acceleration)- Measurement accuracy: ±0.1% FS (full scale)- Sampling rate: 10kHz per channel (ensures capture of high-frequency vibration components)
