Description
Bently Nevada 3300/16-11-01-02-00-02-00 Dual Vibration Monitor
Configured for dual-channel vibration measurement in the Bently Nevada 3300 monitoring system, the Bently Nevada 3300/16-11-01-02-00-02-00 (3300/16 Dual Vibration Monitor) provides direct conditioning and electrical conversion of proximity probe signals into proportional vibration outputs and relay logic states.
The module processes two independent eddy-current transducer inputs, performs amplitude scaling against a 0-10 mils peak-to-peak full-scale range, and generates both buffered dynamic signals and 4-20 mA analog outputs for downstream monitoring and protection logic. Alarm thresholds are evaluated continuously for Alert and Danger relay actuation.

Cross-Talk Suppression and Rotor Dynamics Processing (Bently Nevada TSI Architecture)
The module implements channel separation logic to reduce cross-coupling between adjacent vibration measurement paths in multi-channel rack configurations. Input conditioning is aligned with eddy-current probe scaling characteristics (typical 200 mV/mil sensitivity) to maintain linear response across the defined air-gap voltage range.
Rotor dynamic behavior is represented through amplitude-domain conversion of shaft relative motion, where phase integrity is preserved across buffered outputs to support external diagnostic systems. Signal isolation between channels is maintained at the front-end conditioning stage to prevent measurement contamination during high-energy mechanical transients.
FrequentlyAskedQuestions
Q: Can the 3300/16 module operate with hot-swap insertion in an active rack?
A: The module is not designed for hot-swap operation. Insertion or removal requires system power isolation to prevent backplane transient disturbance and relay state instability.
Q: What is the impact of backplane loading on signal stability?
A: The module draws power directly from the 3300 rack backplane. Excessive cumulative rack loading can introduce voltage droop affecting analog scaling accuracy across all installed modules.
Q: Are the buffered outputs isolated between channels?
A: Channel buffered outputs are independently conditioned, but share common module grounding. External isolation must be implemented at system integration level if galvanic separation is required.
FieldInstallationGuidelines
The module shall be installed only in a compatible Bently Nevada 3300 rack chassis with verified backplane integrity. Ensure all proximity probe wiring uses shielded twisted pair conductors with single-point grounding at the monitor end to prevent ground loop formation.
Maintain minimum separation between signal cabling and high-voltage conductors to reduce electromagnetic interference coupling into low-level proximity signals. Probe extension cable connections must maintain proper coaxial continuity to preserve eddy-current signal linearity.
All relay output wiring shall be routed separately from analog signal paths. Verify terminal torque values according to rack installation specification to avoid intermittent contact resistance during vibration exposure.
