In the field of industrial equipment monitoring and protection, Bently Nevada's 3500 Series undoubtedly stands out as an industry leader.

Model Example: Bently Nevada 3500/72M

The 3500/72M is a monitoring module produced by Bently Nevada, primarily used for monitoring vibration and positional changes in large rotating machinery. This module features the following main functions:

Piston Rod Position Measurement: Monitors changes in the position of the piston rod to ensure the normal operation of the machinery.

Piston Rod Drop Measurement: Monitors positional changes during the descent of the piston rod to prevent mechanical damage caused by excessive dropping.

Ultra-High Pressure Compressor Measurement: Monitors the operating status of high-pressure compressors to ensure they operate within safe pressure ranges.

The 3500/72M module is typically applied in situations requiring precise monitoring and control of piston rod positions, such as reciprocating compressors, gas compressors, etc. Its continuous online monitoring capabilities enable maintenance personnel to promptly identify potential issues and take corresponding maintenance measures to ensure stable equipment operation and extend service life.

Features of the 3500 Series

Redundant Design: The 3500 Series system offers multiple redundancy levels, ranging from single modules to dual power supplies, and up to full TMR (Triple Modular Redundancy) configurations. The TMR configuration employs a 2-out-of-3 voting rule and dedicated relays to ensure that the system will not mistakenly trip or fail to trip due to electronic faults or human errors in any situation.

Self-Detection and Fault-Tolerant Design: The system has self-detection and fault-tolerant capabilities, able to identify faults in monitor modules and sensors connected to them, and to issue and confirm faults through corresponding error codes. When faults jeopardize the correct operation of the system, it will automatically disable channel operation.

External Terminal Options: The 3500 Series provides innovative external terminal options, allowing field wiring to be directly connected to external terminal blocks, which can be installed in more convenient locations such as cabinet walls. This design improves the congestion of wiring connected to the back of each monitor module, making wiring neater and easier to install.

Powerful Alarm and Event Lists: The system features powerful alarm and event list functions, containing the most recent 1000 alarms and 400 system events (configuration changes, errors, etc.). These lists can be viewed through display devices and operator display software, or output to process control, historical data, or other factory systems via communication gateway modules.

Easy Maintenance and Expansion: All modules and power supplies (when using redundant power supplies) can be plugged and unplugged in the frame under live conditions, making maintenance and system expansion more convenient without interrupting machinery protection functions or system operation.

Application Range

Bently Nevada's 3500 Series monitoring system is primarily used to monitor vibrations in large rotating machinery, including but not limited to steam turbines, water turbines, fans, compressors, turbo-expanders, motors and generators, exciters, gearboxes, pumps, etc. This system plays a significant role in production process control and optimization in industries such as petrochemicals, power, steel, and papermaking.

For example, in the petrochemical industry, the 3500 Series system can monitor the position and drop of reciprocating compressor piston rods to ensure that the compressor operates within safe limits. In the power industry, the system can monitor vibrations in steam turbines and water turbines to promptly detect potential faults and avoid shutdown accidents.
