Description
Bently Nevada 3300/16-12-01-01-00-00-00 Vibration Monitor Module
The Bently Nevada 3300/16-12-01-01-00-00-00, also cataloged as the 3300/16 Vibration Monitor Module, operates as a dedicated hardware component for multi-channel vibration and position signal processing within the Bently Nevada 3300 rack monitoring platform. The module processes proximity probe and seismic transducer inputs through rack-bus acquisition, producing alarm logic outputs and condition data streams.

Eddy-Current Probe Scaling and Cross-Channel Signal Conditioning
The module processes eddy-current probe signals through internal scaling networks aligned to displacement-to-voltage transfer functions. Input channels apply gain normalization to maintain consistent gap voltage representation across probe sets, including axial position measurement chains.
Cross-channel signal processing is synchronized at rack level, reducing phase drift between vibration and position channels during steady-state and transient acquisition. The architecture applies channel grouping logic to prevent inter-channel interference in multi-probe configurations, particularly in tightly coupled rotor bearing systems.
Frequently Asked Questions (FAQ)
Q: Does each channel support independent alarm threshold configuration?
A: Yes. Each of the 12 channels supports independent alert and danger threshold parameters with relay output assignment.
Q: Is the module hot-swappable within the 3300 rack?
A: No. The 3300 legacy architecture does not guarantee hot-swap continuity; rack power interruption is typically required for module replacement.
Q: Can 4-20 mA outputs be mapped per channel?
A: Yes. Each dynamic channel can be configured to produce proportional 4-20 mA outputs based on measured vibration or position values.
Field Installation Guidelines
-
Install module into designated 3300 rack slot with backplane alignment confirmed
-
Ensure rack power is isolated before insertion or removal
-
Maintain separation between probe signal wiring and relay output cabling
-
Use shielded twisted-pair conductors for proximity probe inputs
-
Ground cable shields at single-point earth reference only
-
Verify correct probe-to-channel mapping prior to commissioning
-
Avoid routing sensor wiring parallel to high-voltage switching conductors
