Bently Nevada 3500/42M 140734-02 Proximitor Seismic Monitor

Product Details

Manufacturer: Bently Nevada
Series: 3500/42M
Model/Part Number: 140734-02
Model Type: Proximitor Seismic Monitor

Description

The 3500/42M Proximitor Seismic Monitor is a four-channel monitor that continuously monitors machinery health by comparing proximity and seismic transducer signals to user-configured alarm setpoints. It provides critical data on vibration and position measurements, supporting both operations and maintenance personnel by communicating key machine information.

This monitor protects machinery by: 

• Triggering alarms when parameters exceed configured thresholds.
• Accepting input from up to four proximity, velocity, or acceleration transducers.
• Conditioning and comparing signals with programmable alarms for reliable machinery protection.
