3500/42140734-02 Bently Nevada Proximitor Seismic Monitor Card

Product Description

The Bently Nevada 3500/42M 140734-02, also cataloged as the 3500/42M Proximitor Seismic Monitor Card, operates as a dedicated hardware component for vibration and shaft position signal processing within the Bently Nevada 3500 Monitoring System.

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics Monitoring

The Bently Nevada 3500/42M 140734-02 processes dynamic and static vibration signals from eddy-current proximity probes and seismic transducers. The module applies probe scaling parameters to convert field signals into engineering values for shaft displacement and vibration analysis.

Additionally, the card supports gap voltage validation functions for proximity probe measurements. The system uses -10 VDC gap voltage targets as a reference point for verifying probe operating conditions and mechanical installation alignment.

The module supports rotor dynamics monitoring functions including radial vibration, thrust position, differential expansion, eccentricity, shaft absolute measurement, and rolling element bearing activity monitoring. Therefore, the card provides configurable signal processing paths for rotating equipment protection applications.

Frequently Asked Questions

Q: How many measurement channels does the Bently Nevada 3500/42M 140734-02 support?
A: The module supports four independent monitoring channels. Each channel can be configured for proximity, velocity, or acceleration measurement functions.

Q: Does the 3500/42M 140734-02 provide direct field signal access for testing?
A: Yes. The module provides buffered front-panel coaxial outputs for each channel, allowing external analyzers and test equipment to access processed signals.

Q: What type of sensors can connect to the 3500/42M 140734-02?
A: The module accepts signals from Bently Nevada eddy-current proximity probes, Velomitor velocity sensors, and acceleration transducers.

Field Installation Guidelines

• Install the 3500/42M 140734-02 in an approved Bently Nevada 3500 rack slot position according to the rack configuration manual.
• Verify the rack backplane connection before applying system power.
• Connect proximity probe wiring with appropriate shielding and grounding practices to reduce electrical interference.
• Route vibration sensor cables separately from high-voltage power cables and switching circuits.
• Confirm probe gap voltage values during commissioning, and verify that the sensor operates within the configured measurement range.
• Use the 3500 Rack Configuration Software to assign channel functions, alarm limits, and signal scaling parameters.
• Check front-panel LED indicators after installation to confirm module operating status and communication activity.
