Product Description
The Bently Nevada 3500/42M-09-00 Proximitor Seismic Monitor is a four-channel, high-performance module used in the 3500 Series Machinery Protection System. It accepts inputs from proximity and seismic transducers to deliver critical condition monitoring functions for rotating machinery. Each channel can be individually configured to monitor a variety of parameters, including vibration, position, acceleration, and more. By continuously comparing signal values to configured alarm setpoints, the monitor ensures timely fault detection to protect equipment and enhance maintenance efficiency.
Each monitor module uses 3500 Configuration Software and supports flexible signal conditioning, allowing users to tailor monitoring settings to specific machine applications. With features like Buffered Outputs, Recorder Outputs, and support for Static Values, the 3500/42M is essential for machinery protection and predictive maintenance.
