Description

The Bently Nevada 3300/16-13-01-02-00-00-00 serves as the primary 3300/16 XY Vibration Monitor utilized to execute continuous, non-contact radial shaft vibration tracking across Bently Nevada 3300 System platforms. The dual-channel instrument continuously conditions dynamic voltage signals received from proximity transducer systems. It quantifies peak-to-peak shaft displacement, drives local front-panel displays, and triggers machine protection relays when preset vibration thresholds are exceeded. The unit performs physical logic execution within a single rack slot to prevent catastrophic machine damage.

Hardware Specifications

Eddy-Current Scaling and TSI Performance

The monitoring circuitry relies on standard eddy-current probe scaling configurations, typically mapped to a nominal 200 mV/mil input sensitivity derived from 8 mm proximity transducers. Technicians perform manual gap voltage validation through front-panel buffered outputs to confirm the probe operates within its steady -10 VDC linear calibration range. The processing core filters raw orbital paths to isolate specific rotor dynamics, allowing plant operators to distinguish between normal shaft runout and severe faults such as unbalance, misalignment, or fluid-film bearing instability. Advanced internal shielding measures optimize cross-talk suppression between the X and Y orthogonal channels, ensuring accurate phase angle measurement and stable orbital waveform generation.

Frequently Asked Questions

Q: Can this monitor card be extracted from the rack while the power supply module is actively energized?

A: Yes, the 3300/14 power supply allows individual monitor extraction, but hot-swapping can cause accidental relay state changes. Operators must bypass or inhibit all connected trip circuits prior to physical extraction.

Q: Does the -02 intrinsic safety insert option eliminate the need for external zener isolation barriers?

A: Yes, the internal safety inserts act as an integrated barrier layer. This option allows direct field wiring connection from hazardous areas directly to the rack backplane without external DIN-rail barrier enclosures.

Field Installation Guidelines

• Insert the card firmly into the rack slot, then tighten the rear backplane terminal block screws to eliminate high-resistance connections along the signal path.
• Wire the X and Y probes to their respective designated terminal points. Swapping the inputs will invert the physical coordinate system and invalidate orbital phase analysis.
• Route the 4-20 mA analog output lines inside grounded steel conduit runs to maximize noise-rejection parameters near high-voltage motor starters.
• Connect the common instrument ground bus line explicitly to the primary system rack earth point, ensuring total separation from dirty structural ground planes.
