Bently Nevada 330103-00-20-10-02-00 3300 XL Metric Proximity Probe

Description

330103-00-20-10-02-00 specifies a 3300 XL 8 mm metric proximity probe with an M10 x 1 thread and no armor, configured with a 0 mm unthreaded length (Option 00) and a 20 mm overall case length (Option 20). This configuration is unarmored and includes a 1.0 meter total cable length (Option 10) terminated in a miniature coaxial ClickLoc connector on standard cable (Option 02) with no hazardous area approvals (Option 00). The probe operates as a non-contacting eddy-current sensor, generating an output voltage proportional to the gap between the probe tip and the target shaft.

This metric variant provides physical interchangeability with alternative thread designs while maintaining the same electrical performance across the 3300 XL transducer family. By measuring shaft vibration and axial position, the probe enables predictive maintenance and machinery protection on fluid-film bearing machines, Keyphasor reference setups, and high-speed rotating equipment. The 8 mm probe tip diameter offers a robust mechanical structure and a thicker encapsulation of the internal coil within the polyphenylene sulfide tip compared to smaller probe variants.

Features

• Threaded casing with an M10 x 1 metric thread profile and 0 mm unthreaded length for maximum threading contact.
• Unarmored 1.0 meter standard coaxial cable with flexible construction for clean conduit routing.
• Miniature ClickLoc coaxial connector featuring a gold-plated click-type interface for stable signals.
• Polyphenylene sulfide tip material rated for industrial fluids, lubricating oils, and chemical exposure.
• Compatible with standard 3300 XL 5-meter and 9-meter extension cables and Proximitor sensors.

Applications

• Shaft radial vibration monitoring on fluid-film bearings.
• Rotor axial position and thrust measurement.
• Keyphasor reference and rotational speed sensing.
• Turbomachinery diagnostics in power generation, oil and gas, and petrochemical refining.

Installation Guidelines

• Thread the probe into a pre-drilled M10 x 1 tapped mounting hole on the machine casing.
• Thread engagement length must not exceed 15 mm to prevent thread binding during installation.
• Observe the maximum rated installation torque of 11.2 N-m (100 in-lbf) for forward-mount probes.
• Set the sensor gap using a voltmeter to verify the target DC bias voltage from the matched Proximitor sensor.
• Maintain the minimum cable bend radius of 25.4 mm (1.0 in) during cable installation and routing.
• Protect the ClickLoc connector from dirt, oil, and moisture by routing the cable in appropriate conduit.
