Description

The Bently Nevada 3500/40-02-01, also cataloged as the 3500/40 Proximitor Monitor Module, operates as a dedicated hardware component for proximity transducer signal acquisition and machinery vibration measurement within the Bently Nevada 3500 Monitoring System.

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics Interface

The Bently Nevada 3500/40-02-01 Proximitor Monitor Module directly accepts proximity transducer signals and processes shaft displacement measurements through the 3500 monitoring rack architecture. The module supports eddy-current probe scaling by applying configured transducer characteristics to convert probe electrical responses into monitored vibration and position values.

Furthermore, the module handles signals from 1 to 4 proximity transducers and provides channel-level processing for rotor dynamics applications. The internal termination design integrates field signal termination within the I/O module structure, reducing additional external termination requirements.

The module supplies -24 Vdc excitation for compatible proximity transducers and maintains defined electrical characteristics through a 550 Ω output impedance and 10 kΩ standard I/O interface. Therefore, correct probe connection, cable shielding, and signal routing directly influence measurement stability and channel performance.

Frequently Asked Questions

Q: How many proximity transducer signals can the 3500/40-02-01 accept?
A: The module accepts from 1 to 4 proximity transducer signals for configured monitoring channels.

Q: Does the module include internal field signal termination?
A: Yes. The module uses a Proximitor I/O Module design with internal termination.

Q: What transducer power supply does the module provide?
A: The module provides a -24 Vdc transducer power supply for compatible proximity measurement devices.

Field Installation Guidelines

Install the Bently Nevada 3500/40-02-01 Proximitor Monitor Module into the designated 3500 rack position after removing rack power. Next, verify that the module connector seats correctly with the rack backplane before energizing the system.

Connect proximity transducer cables according to the approved Bently Nevada wiring configuration. In addition, route probe signal cables separately from high-voltage and high-current conductors to reduce electromagnetic interference.

Terminate cable shields according to the site instrumentation grounding practice. After wiring completion, verify channel assignment, transducer configuration, and signal response before enabling machinery monitoring functions.
