The Bently Nevada 3500/42M-04-00 is a high-performance Proximitor/Seismic Monitor Module designed for use within the 3500 Machinery Protection System. It is a multifunctional monitoring module that combines proximity measurement and seismic vibration monitoring capabilities for continuous protection of critical rotating machinery.
The main purpose of the 3500/42M-04-00 is to process signals from proximity probes and seismic sensors, providing accurate measurement of shaft vibration, casing vibration, shaft position, and other important machine operating parameters.
This module is designed for machinery where both shaft dynamic behavior and structural vibration conditions need to be monitored. By combining different measurement technologies in one module, it provides a comprehensive view of machine health and operating stability.
The module receives input signals from eddy current proximity sensors, velocity sensors, and seismic transducers. These signals are processed internally to provide reliable vibration and position measurements for protection and condition monitoring applications.
The 3500/42M-04-00 supports continuous online monitoring, allowing operators to observe machine conditions during normal operation. When vibration levels or position values exceed configured limits, the module can generate alarm and protection signals.
The module is commonly applied to large rotating equipment such as turbines, compressors, generators, pumps, and motors. These machines require accurate vibration monitoring to prevent mechanical damage and unexpected downtime.
The modular rack-mounted design allows the module to be installed together with other protection modules in the 3500 system. It communicates through the internal rack backplane, providing reliable data transmission and system coordination.
The plug-in structure allows convenient installation, replacement, and maintenance. The module can be exchanged without extensive changes to cabinet wiring.
The 3500/42M-04-00 provides a combination of accurate measurement, flexible configuration, and reliable protection functions, making it suitable for demanding industrial machinery monitoring applications.
