Configured for non-contacting displacement and vibration measurements in machinery asset monitoring systems, the Bently Nevada 330103-00-15-50-02-00 (330103 Proximity Probes) provides direct physical/electrical execution.

Hardware Specifications

Eddy-Current Probe Scaling and Signal Validation

The 3300 XL series utilizes standardized eddy-current probe scaling to convert target proximity into a linear voltage signal. To maintain measurement accuracy in high-temperature or high-vibration machinery, the installation requires precise gap voltage validation, with targets typically set to -10 VDC at the Proximitor output for a standard target (AISI 4140 steel). This midpoint alignment ensures the linear range (0.25 mm to 2.30 mm) is fully utilized for vibration and axial thrust telemetry. Proper shielding and routing are required to provide effective cross-talk suppression in high-density sensor arrays, preventing signal interference that could otherwise compromise the integrity of rotor dynamics data acquisition.

Frequently Asked Questions

Q: Can the 330103 probe be utilized without a 3300 XL Proximitor sensor?

A: No. The probe is a passive inductive component that requires a matching 3300 XL Proximitor to function as an active transducer system.

Q: Is this probe model interchangeable with older 3300 non-XL components?

A: Yes, 3300 XL 8 mm probes are electrically and physically compatible with legacy 3300 series 8 mm systems, provided the mounting space and cable bend radius specifications are observed.

Q: What is the impact of the unarmored cable construction?

A: The unarmored cable provides lower profile routing and flexibility compared to armored variants, though it requires protection if exposed to physical abrasion or industrial fluids.

Field Installation Guidelines

• Ensure the target mounting surface is clean and free of ferrous contaminants that could alter the eddy-current field.
• Thread the probe into the mounting bracket by hand to prevent thread damage or physical impact to the probe tip.
• Utilize a digital micrometer to verify the initial mechanical gap before finalizing the probe position.
• Connect the probe to the extension cable and Proximitor, ensuring the ClickLoc connectors are fully locked.
• Perform a gap voltage validation check, adjusting the probe depth until the signal reads approximately -10 VDC at the Proximitor output terminals.
• Tighten the locknut to the recommended torque specifications for the M10 x 1 thread size to avoid case deformation.
• Secure all cabling to fixed supports, ensuring the cable is not under mechanical tension and maintains the required minimum bend radius.
