Description

The Bently Nevada 330104-00-18-10-02-05, also cataloged as the 330104 3300 XL 8mm Proximity Probe, operates as a dedicated hardware component for non-contacting shaft displacement and vibration measurements within a Bently Nevada 3300 or 3300 XL Proximitor Sensor loop. The device converts physical gaps between the probe tip and the target rotating shaft into linear electrical variations.

Hardware Specifications

Machinery Monitoring and TSI Characteristics

The 330104-00-18-10-02-05 utilizes eddy-current probe scaling to establish a linear voltage relationship relative to target distance, typically calibrated to 7.87 V/mm (200 mV/mil) when paired with AISI 4140 steel. During field calibration, gap voltage validation targets a nominal -10 VDC output at the center of the linear range, corresponding to an approximate 1.0 mm physical gap. This precise baseline allows the transducer system to monitor high-frequency rotor dynamics with absolute fidelity, capturing precise metrics for fluid-film bearing oil whirl, shaft whip, and synchronous unbalance without mechanical contact.

Frequently Asked Questions

Q: What physical parameter does the -18 option signify in this complete model code?

A: The -18 option designates a 180 mm total case length for the threaded barrel, facilitating mechanical insertion through thick outer machine casings.

Q: What physical parameter does the -05 suffix change specify?

A: The -05 suffix designates the inclusion of multiple approvals and a specific regional compliance rating for explosive atmospheres alongside standard intrinsic safety ratings.

Field Installation Guidelines

• Mechanical Gapping: Rotate the probe inside the mounting bracket while checking the DC bias voltage at the Proximitor output terminal. Stop rotation once the multimeter reads exactly -10.0 VDC, indicating the nominal physical gap is achieved.
• Torque Limits: Tighten the M10 jam nuts to a maximum torque specification of 10.2 N-m (90 in-lb) to prevent shearing or crushing the internal threaded barrel.
• Coaxial Protection: Wrap the ClickLoc connector interface with self-fusing silicone tape or utilize the integrated connector protector sleeve to completely seal the junction against oil and moisture.
