Description

The Bently Nevada 135489-03 is a 4-channel Barrier Seismic I/O Module designed for use within the 3500 Series machinery protection system. This module features internal safety barriers and is specifically engineered to interface with seismic transducers, providing essential signal conditioning for vibration monitoring in critical rotating and reciprocating machinery. It serves as a key component in the 3500/70M Recip Impulse Velocity Monitor configuration, facilitating the detection of crankcase and crosshead vibration to ensure operational reliability.

Features

• 4-channel seismic input processing with internal barriers.
• Supports integration with Velomitor sensors.
• Configurable alarm setpoints for alert and danger conditions.
• Designed for reciprocating compressor monitoring applications.
• Provides conditioned signals for vibration measurement and analysis.

Applications

• Reciprocating Compressors: Monitoring crankcase and crosshead vibration for early failure detection.
• Turbine Protection: Monitoring bearing and stator winding conditions to prevent overheating.
• Chemical and Petrochemical Processing: Managing reciprocating equipment reliability in hazardous environments.
• Pipeline Compression: Ensuring the continuous operation of large-scale compressor stations.
• Oil and Gas Production: Supporting gas compression in both upstream and downstream operations.

Technical Specifications

Installation Guidelines

• The I/O module must be installed in the rear of the 3500 rack, directly behind the associated monitor module.
• Ensure the module is aligned with the slot guides before sliding it into the rack.
• Slide the module firmly until the connectors fully mate with the backplane.
• Tighten the top and bottom captive screws to secure the module and ensure a proper chassis ground connection.
• Always power down the rack or follow site-specific safety procedures before inserting or removing modules to prevent damage to the backplane or circuitry.

FAQs

What is the 135489-03?

It is an I/O module for the Bently Nevada 3500 monitoring system, featuring internal barriers to support seismic sensor inputs for vibration monitoring.

What does this module monitor?

It supports four channels, typically used for processing data from Velomitor sensors to monitor parameters such as acceleration and velocity in reciprocating compressors.

Is this module compatible with older systems?
