Description

The Bently Nevada 330104-00-09-10-02-00, 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 330104-00-09-10-02-00 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 -02 option signify in this complete model code?

A: The -02 option designates a standard miniature coaxial ClickLoc connector with an integrated connector protector, preventing fluid intrusion and mechanical damage at the cable interface.

Q: Can this 1.0 meter probe cable be coupled directly to a Proximitor without an extension cable?

A: No. The total system length must equal 5.0 or 9.0 meters depending on the specific Proximitor model chosen. Operating a 1.0 meter probe without the matching 4.0 or 8.0 meter extension cable causes absolute calibration failure.

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.
