Products Description
The Bently Nevada 3500/42M Proximitor Seismic Monitor is designed to safeguard machinery by continuously evaluating monitored signals against pre-set alarm thresholds. It provides critical information to both operations and maintenance teams, enabling timely responses to abnormal conditions. This four-channel monitor accepts inputs from proximitor and seismic sensors, processes the signals to produce accurate vibration and position readings, and compares them to configurable alarm levels. Depending on how each channel is set up, it generates several parameters known as static values. Users can set alert limits for all active static values and define danger limits for up to two of them, ensuring precise machinery protection and operational awareness.

Advantage
The 3500/42M provides continuous monitoring of machinery by evaluating inputs from proximity and seismic transducers. Each channel generates static values that are compared against configurable alert and danger setpoints, triggering alarms whenever thresholds are exceeded. This ensures early detection of abnormal vibration or positional changes, protecting turbines, compressors, pumps, and other critical machinery from potential damage. The monitor's fault-tolerant design allows uninterrupted operation even if recorder outputs experience short circuits, making it highly reliable for continuous industrial operations.
Industrial Applications
Beyond alarm functionality, the 3500/42M provides essential operational data for maintenance teams. Buffered recorder outputs and high-accuracy static values support trend analysis and predictive maintenance strategies. Its robust design, including short-circuit protected outputs and –24 V DC transducer supply, ensures reliable signal acquisition in harsh industrial environments. This enables operators to detect subtle performance changes, optimize maintenance schedules, and reduce unplanned downtime.
