Bently Nevada 3500/42M 176449-02 Proximitor Seismic Monitor Without I/O Module
Product Overview
The Bently Nevada 3500/42M 176449-02 is a four-channel proximitor/seismic monitor that continuously measures radial vibration, axial position, or seismic activity on critical turbomachinery. Installed in any 3500 rack, it interfaces with 3300 XL proximity probes or accelerometers to provide ±0.1 % accuracy alarm outputs, 4–20 mA trend signals, and dynamic waveform data via System 1 or AMS Machinery Health. SIL 2 certification and hot-swap capability ensure maximum safety and uptime for refineries, petrochemical plants, and power generation.
Key Features & Benefits
• 4 universal channels – configurable for radial vibration, axial position, or seismic
• ±0.1 % full-scale accuracy – precise alarm set-points
• 4–20 mA outputs per channel – direct DCS/PLC integration
• 0–10 kHz frequency response – captures high-speed machinery faults
• Hot-swap module – replace without shutting down the 3500 rack
• SIL 2 / IEC 61508 certified – meets safety-instrumented system requirements
• Front-panel LEDs – channel OK, alarm, bypass status at a glance
• Backward-compatible firmware – seamless upgrade from 176449-01
Typical Applications
• Steam & gas turbine radial vibration protection
• Centrifugal compressor axial position monitoring
• Generator seismic vibration analysis
• Motor-driven pump train diagnostics
