描述
The Bently Nevada 3500/42M Proximitor Seismic Monitor is a four-channel condition monitoring module engineered for continuous machinery protection. It accepts signals from proximity and seismic transducers to measure radial vibration, thrust position, differential expansion, acceleration, and other critical parameters. The model 176449-02 Monitor is typically paired with the 140471-01 I/O Module for Prox/Velom inputs with internal termination.

FAQ
1. What is the primary function / the 3500/42M Proximitor Seismic Monitor?
It provides continuous monitoring and protection / rotating machinery by measuring and analyzing vibration and position parameters from proximity and seismic sensors.
2. What types / transducers are supported?
The monitor supports proximity probes, Velomitor® velocity sensors, accelerometers, and seismic probes.
3. Can I configure different functions on different channel pairs?
Yes, channels are configured in pairs and can perform different measurement types independently (e.g., vibration on one pair, thrust on the other).
4. What output options are available for the monitor?
Each channel includes 4–20 mA recorder outputs and buffered transducer outputs. Shaft Absolute outputs are available on dedicated modules.
5. What alarm functions are available?
Each active static value can have alert setpoints; any two can have danger setpoints. Alarm delays are also configurable.
6. Is the 3500/42M suitable for hazardous environments?
Yes, it meets ATEX, IECEx, CSA, and cNRTLus requirements for Zone 2/Division 2 areas.
7. What are typical applications for this monitor?
It is commonly used for turbine generators, compressors, pumps, and other high-value rotating machinery requiring advanced condition monitoring.
8. How accurate are the vibration measurements?
Accuracy is typically within ±0.33% / full-scale, up to ±1% maximum for most functions.
9. What s/tware is required for configuration?
3500/01, 02, or 03 s/tware versions (depending on firmware) are used with the 3500/42M monitor for setup and diagnostics.
10. Can this module be used in marine or /fshore installations?
Yes, it complies with ABS and DNV GL standards for marine and /fshore applications.
