Rotor Dynamics Signal Acquisition and TSI Data Processing
The Bently Nevada 3500/23E performs transient waveform collection for machinery protection analysis within the 3500 monitoring platform. The module supports up to 16 input channels and captures dynamic vibration-related signals with sampling rates up to 100 kHz.
The module provides adjustable ADC resolution from 12-bit to 16-bit. Therefore, users can configure measurement resolution according to waveform analysis requirements. The 500 V channel-to-ground isolation structure reduces electrical interference between measurement circuits and system ground references.
For Bently Nevada monitoring applications, the module supports rotor dynamics evaluation functions, including transient vibration behavior analysis and machinery event recording. In addition, the interface maintains signal integrity for eddy-current probe systems by supporting accurate waveform acquisition from proximity measurement channels.
The 3500/23E installation design follows API 670 machinery protection system requirements. Furthermore, the module architecture supports gap signal monitoring practices, including validation of probe operating conditions and typical -10 VDC gap voltage targets used in eddy-current measurement systems.

Field Installation Guidelines
Install the Bently Nevada 3500/23E module inside the designated 3500 rack slot and verify correct backplane engagement before operation.
Use shielded signal cables for field wiring connections. Connect cable shields according to the site grounding design to reduce electromagnetic interference during transient signal acquisition.
Separate proximity probe wiring from high-voltage power cables and switching circuits. Maintain proper cable routing practices to prevent signal coupling and measurement distortion.
Verify eddy-current probe connections, polarity, and gap voltage conditions before enabling machinery monitoring functions. Confirm that the measured probe operating point matches the required monitoring range.
Check rack power availability and system communication status after installation. Complete channel configuration and signal verification through the applicable 3500 system software before placing the monitoring system into service.
