Technical Specifications

FAQ

1. What is the primary function of the 3500/42M Proximitor Seismic Monitor?

It provides continuous monitoring and protection of rotating machinery by measuring and analyzing vibration and position parameters from proximity and seismic sensors.

2. What types of 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% of full-scale, up to ±1% maximum for most functions.

9. What software is required for configuration?

3500/01, 02, or 03 software versions (depending on firmware) are used with the 3500/42M monitor for setup and diagnostics.

10. Can this module be used in marine or offshore installations?

Yes, it complies with ABS and DNV GL standards for marine and offshore applications.
