Bently Nevada 3300/16 Vibration Monitor Module
Configured for dual-channel radial vibration and shaft gap electrical conversion in 3300 rack based proximity transducer networks, the Bently Nevada 3300/16-15-01-03-00-00-00 (3300/16 XY/GAP Dual Vibration Monitor) provides direct physical/electrical execution of eddy-current probe signal conditioning and alarm logic processing across Bently Nevada 3300 monitoring platforms.
The module processes two independent proximity probe inputs with fixed sensitivity scaling (200 mV/mil) and converts shaft displacement into conditioned peak-to-peak vibration and DC gap voltage signals. Internal alarm logic supports relay output configuration (quad relay epoxy sealed type) for threshold-based trip and warning states.

Eddy-Current Probe Scaling and Gap Voltage Validation Behavior
The 3300/16 platform applies fixed eddy-current probe scaling using calibrated 200 mV/mil sensitivity conversion to translate probe air-gap variation into electrical displacement signals. Gap voltage validation is referenced against stable DC operating points derived from proximity probe bias conditions, enabling continuous monitoring of shaft centerline position drift. Cross-channel interaction suppression is implemented at analog conditioning stage to reduce coupling between X and Y measurement paths during high amplitude rotor orbit conditions.
Frequently Asked Questions
Q: Can the quad relay output be used for independent alarm zoning?
A: Yes, the quad relay configuration supports discrete alarm assignment per channel or combined logic outputs depending on backplane configuration.
Q: Does the module require software configuration for scaling?
A: Scaling is hardware-defined via factory option (-15), no field programmable scaling is applied to the measurement chain.
Q: Is channel synchronization required for X-Y vibration measurement?
A: Channels operate in parallel analog paths; phase relationship is preserved inherently without digital synchronization logic.
Field Installation Guidelines
-
Install module only into compatible 3300 rack slot with secure backplane engagement
-
Verify proximity probe wiring polarity and shielding continuity before energization
-
Use single-point grounding for coaxial and probe cable shields to avoid ground loop currents
-
Maintain separation between signal cabling and high voltage conductors to reduce induced noise
-
Ensure relay output wiring matches intended alarm logic configuration prior to system start-up
