The Bently Nevada 3300/16-15-01-03-00-00-02 serves as the primary 3300/16 Dual Vibration XY/GAP Monitor utilized to execute continuous radial vibration and probe gap voltage tracking across 3300 System platforms. The hardware accepts dual independent signals from proximity transducers to determine dynamic shaft displacement relative to the bearing journal housing, routing raw analog signals directly to the backplane communication loop for structural machinery diagnostics.

Hardware Specifications

Rotor Dynamics and Probe Scaling

The 3300/16-15-01-03-00-00-02 utilizes specialized eddy-current probe scaling matrices to linearize input voltages across a wide operational envelope. The internal circuitry provides direct gap voltage validation against standardized -10 VDC targets, allowing precise calibration of the proximity sensor's static position within the fluid-film bearing. Built-in cross-talk suppression paths isolate the X and Y orthogonal transducer channels, preventing spatial frequency interference from introducing phase tracking errors during high-speed rotor dynamics evaluation.

Ordering Info

Field Installation Guidelines

• Chassis Slot Alignment
  • Insert the circuit board straight into the designated 3300 rack chassis rails, ensuring full contact alignment with the backplane multi-pin connector before tightening panel screws.
• Transducer Shielding Separation
  • Terminate the incoming coaxial Proximitor cable shields directly at the dedicated monitor backplane ground terminals, keeping them isolated from high-current power grounds.
• Power Rail De-energization
  • Turn off the main 3300 system power supply module prior to inserting or removing the monitor interface card to prevent internal component damage from voltage spikes.
• Signal Output Routing
  • Route the unbuffered front-panel coaxial output lines using low-capacitance test cables to maintain signal accuracy when logging data on diagnostic oscilloscopes.

Frequently Asked Questions

• Can this specific 3300/16 monitor card be hot-swapped while the 3300 rack assembly is online?

  No. The 3300 system architecture requires the rack power supply to be turned off before inserting or extracting monitor modules to avoid data corruption or component damage.

• What is the default operation status of the alarms since this option is designated as No Relays?

  The monitor processes Alert and Danger logic internally to drive the front LEDs and backplane communication, but an external relay module is needed for physical machine trips.

• How does the monitor validate the -10 VDC gap voltage target if the probe face moves out of range?

  The GAP meter on the front display shifts proportionally, and if the DC voltage limit goes outside the preset window, the OK LED turns off to show a transducer fault.

• What is the maximum permissible length for the proximity transducer cable connecting to the backplane?

  The system is calibrated for standard 5-meter or 9-meter total system lengths; exceeding these limits alters the eddy-current probe scaling and causes measurement drift.

• Can this monitor interface directly with a 3300 XL 8 mm proximity probe assembly?

  Yes, option -01 configures the internal tracking circuitry to accept input scaling from standard 3300 8 mm and 3300 XL 8 mm Proximitor sensors.

• How is the 4-20 mA analog output loop powered on the rear terminal block?

  The 4-20 mA recorder outputs are internally powered by the monitor card and must be routed to a passive, non-powered analog input channel on the DCS or PLC.

• What causes the front panel OK LED to flash continuously during initial system boot?

  Flashing during power-up indicates the module is running its internal self-test; persistent flashing means a memory check failure or an uncalibrated hardware loop.

• How are the Alert and Danger alarm setpoints adjusted on this vintage hardware?

  Alarm limits are configured using physical adjustment potentiometers or jumper matrices accessible on the internal circuit boards rather than through software links.
