Configured for high-speed machinery monitoring, the Bently Nevada 330104-00-20-10-02-00 (330104 Proximity Probe) provides direct physical signal transduction for radial vibration, thrust position, and speed reference measurement within TSI platforms.

Suffix Breakdown and Configuration

The 330104-00-20-10-02-00 model is defined by the following specifications:

• 00: M10 x 1 threaded probe (Note: base model specification implies standard thread configuration).

• 20: 2.0 inch case length.

• 10: 1.0 meter (3.3 feet) integral system length.

• 02: Miniature coaxial ClickLoc connector.

• 00: Standard regulatory approval configuration.

Hardware Specifications

Mechanical Monitoring and Signal Integrity

The 3300 XL transducer system utilizes eddy-current probe scaling to convert conductive target proximity into proportional voltage output. System accuracy is contingent upon rigorous gap voltage validation to ensure operation within the linear -10 VDC range. To ensure rotor dynamics data integrity, cross-talk suppression must be implemented in multi-probe arrays. Proper signal isolation prevents spectral interference, maintaining the validity of shaft centerline, eccentricity, and phase reference measurements in high-speed rotating equipment.

Field Installation Guidelines

• Probe Positioning

• Ensure the probe is mounted in a reverse-mount configuration to achieve stable target coverage.

• Adjust the probe gap until the monitoring interface displays the nominal -10 VDC gap voltage.

• Cabling and Terminations

• Use the ClickLoc miniature coaxial interface for a vibration-resistant connection.

• Route cables through dedicated conduit to shield from electromagnetic interference and mechanical damage.

• Ground shields only at the monitor rack to avoid ground loop currents in the sensing circuit.

Frequently Asked Questions

• What is the linear range of this 8 mm probe?

  The probe offers a linear measurement range of 2.0 mm (80 mils), sufficient for detecting radial vibration and thrust displacement.

• Can this probe be used for Keyphasor signals?

  Yes, the high frequency response and sensitivity make this probe suitable for speed and phase reference (Keyphasor) applications.

• Is the thread size standard?

  This unit features a 3/8-24 UNF thread size, typical for reverse-mount 3300 XL probe applications.

• What is the impact of the ClickLoc connector?

  The ClickLoc connector is designed to provide a secure, locking mechanical interface that prevents signal loss due to vibration.

• Is the probe compatible with 3500 series racks?

  Yes, the 330104 probe integrates with 3500 and 2300 machinery protection systems when paired with an appropriate Proximitor.

• What happens if the gap voltage is outside specification?

  Operating outside the linear -10 VDC target range may result in signal clipping, leading to distorted vibration data.

• Does this probe require external power?

  No, the transducer is passive and powered through the Proximitor unit via the coaxial signal cable.

• Can I use this probe in fluid-film bearings?

  Yes, the probe is standard for monitoring radial vibration in fluid-film bearing configurations.
