Description

The Bently Nevada 3300/16-XX-01-03-00-00-02 serves as the primary 3300/16 XY/Gap Dual Vibration Monitor utilized to execute non-contacting radial shaft vibration and average shaft position gap tracking across 3300 Monitoring System platforms. Specifically, this continuous monitoring module processes the electrical signals from two independent proximity probe systems. Consequently, the hardware transfers this raw machinery protection data over the internal rack backplane for real-time alarm valuation and logic voting.

Suffix Breakdown & Model Matrix

• 3300/16: Core module identifier for the XY/Gap Dual Vibration Monitor series.
• XX: Variable placeholder for the full-scale range and engineering unit option (e.g., 01 for 0-5 mils, 02 for 0-10 mils, 15 for 0-15 mils, or metric equivalent alternatives).
• 01: Transducer type input option configured specifically for standard 3300 XL 8 mm proximity probe systems.
• 03: Agency approval certification level option confirming compliance with hazardous area operating standards.
• 00: Internal alarm relay configuration option specifying that the monitor contains no individual mechanical relay boards.
• 00: Trip Multiply option selection designating standard factory bypass and magnification coefficients.
• 02: Front panel interface option equipping the module faceplate with an integrated Liquid Crystal Display (LCD).

Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics

The 3300/16-XX-01-03-00-00-02 processes high-frequency radio signals passing through connected eddy-current probes. During validation procedures, technicians evaluate the continuous gap voltage to maintain a static -10 VDC baseline position. This tracking monitors the calibrated 7.87 V/mm (200 mV/mil) scale factor curve. Furthermore, the specialized filter layout enhances cross-talk suppression between channels if the physical installation spaces multiple probes closely together inside the same bearing housing block. Meanwhile, diagnostic tracking requires precise mechanical runout correction on the shaft target. Without this precaution, micro-structural variances in the steel deform the magnetic flux lines, which introduces parasitic noise into the 3300 backplane and alters true rotor dynamics reporting.

Frequently Asked Questions

Q: How does the monitor respond if an field extension cable disconnects or short-circuits?

A: The monitor features an integrated Not OK detection circuit. If a probe circuit loop opens or experiences an impedance fault, the system drops the channel out of service within 100 milliseconds and inhibits false Alert or Danger alarm actuation.

Q: Can the instrument technician adjust the analog recorder output format on site?

A: Yes, because the recorder outputs are field-programmable. The technician adjusts internal hardware jump links on the circuit board to toggle the output among 4-20 mA, 0 to -10 VDC, or +1 to +5 VDC configurations.

Field Installation Guidelines

• Chassis Slot Alignment: Insert the module into the designated 3300 instrument rack backplane slot guide rails. Push the faceplate firmly until the rear multi-pin card edge connector seats fully into the motherboard sockets, then secure the front panel retaining screws.
• Field Signal Wire Shielding: Route the Proximitor signal wires using twisted-pair shielded cable. Connect the outer drain wire exclusively to the instrumentation ground terminal block located at the rear of the 3300 rack chassis, thereby avoiding multiple ground loops.
• Frequency Configuration Checks: Select the appropriate low-frequency response limit via internal jumpers before startup. For machines with operating speeds below 1000 rpm, implement the 1 Hz (60 cpm) filter profile to ensure accurate signal capture during slow roll validation phases.
