Description

The Bently Nevada 3500/40M 176449-01, also cataloged as the 3500/40M Proximitor Monitor Module, operates as a dedicated hardware component for proximity transducer signal monitoring within the 3500 Monitoring System platform.

Hardware Specifications

Eddy-Current Proximity Signal Processing Characteristics

The 3500/40M Proximitor Monitor Module processes proximity transducer inputs for mechanical displacement monitoring applications. The module accepts signals from up to four proximity transducers and provides electrical conditioning between field sensors and the monitoring system.

The module supports eddy-current probe scaling functions through configured transducer signal handling. Proper probe installation requires verification of probe target distance, signal polarity, and gap voltage conditions before operation. The -10 VDC gap voltage target is commonly used as a reference point during eddy-current probe setup procedures.

The module architecture supports rotor dynamics monitoring functions by transferring proximity signal information into the 3500 monitoring platform for vibration and position analysis. Field wiring separation and shield management reduce signal interference during measurement.

Frequently Asked Questions

Q: Can the 3500/40M 176449-01 accept multiple proximity transducer inputs?
A: The module accepts 1 to 4 proximity transducer signals according to the provided product specifications.

Q: What power supply requirement is specified for the connected transducer circuits?
A: The module provides a 24 VDC transducer power supply for compatible proximity transducer connections.

Q: What installation factors affect proximity signal accuracy?
A: Installation requires correct probe alignment, appropriate cable routing, shield grounding, and verification of signal polarity and gap voltage conditions.

Field Installation Guidelines

Install the module in the designated 3500 rack position and verify mechanical retention before applying power. Confirm that field cables match the required proximity transducer wiring arrangement.

Route proximity signal cables separately from high-current power conductors to reduce electromagnetic interference. Connect cable shields according to the monitoring system grounding practice and avoid multiple uncontrolled grounding points.

Before commissioning, verify transducer connections, power supply status, input signal behavior, and mechanical probe clearances. Confirm that configuration parameters match the installed transducer type and monitored machine application.
