The Bently Nevada 330104-01-14-05-01-05, also cataloged as the 330104-01-14-05-01-05 Proximity Probe, operates as a dedicated hardware component for non-contacting vibration and displacement measurement within 3300 XL monitoring systems.

Model Suffix Configuration

The 330104 series utilizes a modular naming convention to define specific mechanical and electrical properties. The suffix -01-14-05-01-05 represents the physical thread configuration, lead length, connector type, and material assembly, ensuring compatibility with standard proximity transducer monitoring interfaces.

Hardware Physical Specifications

Transducer Electrical Integrity

Accurate eddy-current probe scaling is mandatory for maintaining the 200 mV/mil output sensitivity characteristic of the 3300 XL system. During deployment, the gap voltage validation (-10 VDC targets) must be verified at the monitor or sensor output to ensure the probe resides within the linear operating region of the calibrated curve. Effective cross-talk suppression is achieved via the shielded coaxial design; therefore, the shield must be terminated consistently at the monitor end to prevent noise induction in the rotor dynamics signal path.

Field Installation Protocols

• Surface Integrity: Ensure the target shaft is free of surface irregularities that could cause eddy-current distortion.

• Alignment: Align the probe axis perpendicular to the target surface to maintain linearity.

• Torque Limits: Tighten lock nuts to specified torque to avoid mechanical resonance.

• Shielding: Ensure the cable path remains isolated from high-voltage lines to prevent electromagnetic interference.

• Impedance: Do not alter cable lengths, as the system is calibrated as a matched set (Probe, Cable, Proximitor).

Frequently Asked Questions

• What is the primary use of this probe? It is used for monitoring shaft radial vibration and axial position in turbomachinery.

• Can I replace the coaxial cable? No, the cable is integral to the probe and cannot be removed or replaced in the field.

• How does temperature affect readings? Measurements are drift-compensated within the specified -35 deg C to +177 deg C range.

• Is the probe case grounded? Yes, the stainless steel case is typically grounded through the mounting hardware to the machine.

• What happens if the gap voltage is outside -10 VDC? The signal may deviate from the linear range, resulting in distorted vibration readings.

• Can this be used in explosive atmospheres? Yes, provided it is installed as part of an approved Intrinsically Safe (Ex i) circuit.

• Does it require periodic calibration? The system should be checked periodically; individual components cannot be recalibrated independently.

• How do I identify if the probe is damaged? A change in the nominal gap voltage with no change in physical clearance typically indicates probe failure.
