Bently Nevada 3300/16-12-01-01-00-00-02 Dual Vibration Monitor

The Bently Nevada 3300/16-12-01-01-00-00-02, also cataloged as the 3300/16 Dual Vibration Monitor, operates as a dedicated hardware component for continuous radial vibration monitoring, static shaft alignment tracking, and dynamic machinery protection within Bently Nevada 3300 series monitoring racks. Configured for high-density instrumentation tracking, the monitor card provides direct physical and electrical execution to process input signals from up to two proximity probe transducers concurrently.

Hardware Specifications

Machinery Monitoring and TSI System Metrics

• Eddy-Current Probe Scaling and Gap Voltage Validation The internal conditioning electronics supply a regulated negative bias voltage to the field terminal connections. This architecture stabilizes eddy-current probe scaling matrices across the 10 kΩ input circuits, ensuring that static gap voltage validation targets (-10 VDC targets) remain immune to fluctuating line temperatures and provide accurate proximity feedback data to the logic processing core.
• Rotor Dynamics and Cross-Talk Suppression The dual-channel processing paths calculate peak-to-peak radial vibration metrics to analyze transient rotor dynamics during machine startup and steady-state conditions. Internal multi-layer shielding tracks execute comprehensive cross-talk suppression between the adjacent signal channels, preventing high-amplitude voltage transitions on one probe from inducing artificial measurement spikes or false alarm trips on the secondary monitoring loop.

Frequently Asked Questions

Q: How is the current-limited power supply configured on the 3300/16 monitor card?

A: The card features internal user-programmable jumpers that allow field personnel to select either a -24 VDC or -18 VDC excitation output to drive remote proximity transducers. This power rail is strictly current-limited to safeguard the internal backplane components against field wiring ground faults or terminal shorts.

Q: What action occurs if the sensor gap voltage shifts outside operational parameters?

A: If the static gap voltage crosses predefined out-of-range thresholds, the monitor card identifies a transducer system fault. It immediately illuminates the faceplate "Not OK" indicator, bypasses the associated voting logic to prevent false machinery trips, and generates a dedicated hardware status log on the system bus.
