8. FAQ
-
Q: What does the 3500/42M module do?
A: It accepts signals from proximity probes, processes them, and delivers clean vibration data for monitoring systems. -
Q: How many channels does it support?
A: It typically supports two independent proximity probe channels. -
Q: What kind of sensors can be used with it?
A: Eddy‑current proximity probes designed for shaft displacement or vibration. -
Q: What are its mounting requirements?
A: It mounts in a 19‑inch rack using a 3U slot, powered from the system backplane. -
Q: How much space does it occupy?
A: Roughly 3 rack units high, 19 in wide, and about 250 mm deep; weight around 2.5 kg. -
Q: Can I swap it while the system is running?
A: Yes, if using a hot‑swappable rack version, it can be replaced without shutting down the whole rack. -
Q: What is the signal bandwidth?
A: It processes signals from low frequency (0.1 Hz) up to several tens of kilohertz for dynamic response. -
Q: Is it compatible with earlier systems?
A: Yes, it’s backward compatible in terms of probe type and rack format, though newer features exist. -
Q: Does it require external calibration?
A: Sensing probes may need calibration, but the module itself is factory‑calibrated and seldom needs adjustment. -
Q: What kind of outputs does it provide?
A: Conditioned amplitude and phase outputs (analog), suitable for alarms or data acquisition.
