Bently Nevada 143488-01 3500/40 Proximitor Monitor

The Bently Nevada 143488-01 is a Proximitor Monitor module designed for integration into the 3500/40 series machinery protection system. This four-channel monitor is engineered to process signals from proximity transducers, providing precise vibration and position measurements essential for the continuous monitoring of critical rotating equipment such as turbines, compressors, and pumps.

Features

• Four independent channels for simultaneous signal acquisition.
• Full compatibility with standard Bently Nevada proximity probe systems.
• User-configurable alarm and danger setpoints to facilitate automated machinery protection logic.
• Integrated signal conditioning for vibration, thrust, eccentricity, and differential expansion measurements.
• Front-panel buffered transducer outputs, providing easy access for diagnostic troubleshooting via coaxial connectors.
• Seamless integration with the 3500 rack backplane for power and communication.

Applications

This monitor is utilized in high-criticality industrial environments for the following applications: monitoring shaft radial vibration, axial thrust position, differential expansion in steam turbines, shaft eccentricity, and REBAM (Radial Eccentricity and Blade Amplitude Measurement).

Technical Specifications

Installation Guidelines

• Ensure the 3500 rack is powered down before inserting or removing the module to prevent electrical damage.
• Verify that the module is properly seated in the designated rack slot to ensure reliable backplane communication.
• Use shielded cabling for all transducer inputs to minimize interference from high-EMI industrial environments.
• Maintain adequate airflow within the cabinet to stay within the specified operating temperature range.
• Handle with standard ESD precautions to prevent damage to internal circuitry.

FAQ

What is the primary function of the 143488-01?

The 143488-01 serves as a four-channel Proximitor monitor that conditions raw sensor signals into meaningful vibration and position data, comparing them against programmed limits to trigger alarms if necessary.

Can this module be configured for different sensitivity levels?

Yes, the module supports various sensitivity settings, including 100/200 mV/mil for radial vibration and thrust, 10/20 mV/mil for differential expansion, and 1000/2000 mV/mil for REBAM applications.
