BENTLY NEVADA 3300/16-02-01-00 Vibration Monitors

The Bently Nevada 3300/16-02-01-00, also cataloged as the 3300/16 Dual Vibration Monitor, operates as a dedicated hardware component for continuous processing of dynamic vibration signals and shaft position tracking within 3300 Machinery Monitoring System racks. It conditions continuous AC/DC electrical inputs from proximity probe transducers to deliver direct physical/electrical execution for continuous XY radial vibration and gap voltage evaluation.

Hardware Specifications

Eddy-Current Probe Scaling & Rotor Dynamics Monitoring

The 3300/16 processing circuitry relies on precise eddy-current probe scaling to convert raw RF carrier demodulation into engineering units. Factory-calibrated for 200 mV/mil (7.87 V/mm) sensitivity, the module converts micro-inch shaft displacement into calibrated peak-to-peak amplitude values. Gap voltage validation targets (-10 VDC nominal center bias) confirm probe tip clearance within the linear range prior to dynamic processing. This measurement baseline supports accurate detection of unbalance, misalignment, and oil whirl phenomena in critical rotor dynamics systems.

Frequently Asked Questions

Q: What action occurs if a connected proximity probe experiences a line fault or cable break?

A: The module drives the affected channel into a NOT OK state, illuminates the front-panel NOT OK LED, drops the corresponding 4-20 mA output below 2 mA, and inhibits false trip outputs.

Q: Is hot-swapping permitted for the 3300/16 module during active monitoring operations?

A: Removing or inserting the module while the system rack backplane is powered is not recommended, as edge connector arcing can disrupt backplane communication and cause false voting trips on linked relay modules.

Field Installation Guidelines

• Ensure backplane keying mechanisms align with the module connector prior to fully seating the unit into the 3300 rack chassis.
• Route all field wiring for Proximitor inputs and 4-20 mA outputs through continuous twisted, shielded cable pairs.
• Connect cable shields to a dedicated single-point ground connection at the rack chassis ground bar to avoid ground loops.
• Maintain adequate ventilation above and below the rack frame to preserve nominal convective heat dissipation across internal components.
