常见问题 (FAQ)
Q1: What types / sensors does the 3500/42M support?
A1: It supports proximity probes, Velomitor velocity sensors, and seismic accelerometers.
Q2: Can the module monitor both vibration and position simultaneously?
A2: Yes, channels are configured in pairs to monitor two functions simultaneously, such as vibration and thrust.
Q3: What is the sensitivity range / the module?
A3: Sensitivity varies by input type, with standard proximity input sensitivities at 3.94 mV/µm or 7.87 mV/µm.
Q4: Is this module suitable for hazardous area installations?
A4: Yes, the 135489-02 I/O module includes internal barriers for Class I, Div 2, and ATEX Zone 2 compliance.
Q5: What is the output format / the module?
A5: Each channel provides a 4–20 mA current loop output and coaxial buffered output.
Q6: Does the module support alarm configuration?
A6: Yes, configurable alert and danger alarms are available for each measurement channel via rack configuration s/tware.
Q7: What is REBAM and does this module support it?
A7: REBAM is Rolling Element Bearing Analysis Monitoring, and the 3500/42M supports it on selected channels.
Q8: What environmental limits does the module meet?
A8: It operates from -30°C to +65°C (non-barrier I/O) or 0°C to +65°C (barrier I/O), with 95% RH non-condensing.
Q9: Are channels hot-swappable?
A9: No, the system must be powered down before module replacement.
Q10: How is communication handled within the rack?
A10: The monitor uses TX/RX communication within the 3500 rack and integrates with system s/tware.
