330103-00-15-50-02-00 Bently Nevada 3300 XL 8 mm Proximity Probe

Configured for shaft displacement measurement in rotating machinery, the Bently Nevada 330103-00-15-50-02-00 (330103 3300 XL 8 mm Proximity Probe) provides a non-contact eddy-current sensing interface for rotor position monitoring.

Hardware Specifications

Eddy-Current Measurement and Gap Validation

The 3300 XL 8 mm probe operates as part of an eddy-current proximity measurement system. The probe senses changes in the distance between its sensing tip and the conductive machine target without physical contact.

The M10 x 1 threaded construction supports mechanical positioning at the monitoring location. Because the supplied configuration has no armor, installation should protect the cable and probe body from mechanical damage during routing and maintenance.

For Bently Nevada proximity systems, technicians normally verify probe gap and electrical output against the associated Proximitor interface before placing the measurement channel into service. A typical Bently Nevada installation practice uses a negative DC gap voltage, with approximately -10 VDC commonly associated with a nominal reference position. The exact acceptance value must follow the applicable system documentation and measurement target geometry.

The 5.0 meter cable length provides the specified electrical connection between the probe and compatible signal-conditioning electronics. Therefore, the complete probe, extension cable where applicable, and Proximitor channel should be treated as one calibrated measurement system.

Frequently Asked Questions

Q: What mechanical thread does the 330103-00-15-50-02-00 use?
A: The supplied specification identifies an M10 x 1 thread. The probe has no armor, and its minimum unthreaded length is 0 mm.

Q: What cable configuration does this model use?
A: This configuration specifies a 5.0 meter (16.4 feet) total cable length with a miniature coaxial ClickLoc connector and standard cable.

Q: Does the supplied specification define the operating temperature and power consumption?
A: No. The supplied data does not specify either value. These parameters should therefore be taken from the applicable 3300 XL system documentation rather than estimated.

Field Installation Guidelines

• Confirm the M10 x 1 mounting thread matches the installed mechanical mounting arrangement before installation.
• Maintain the specified minimum case length and avoid forcing the probe into an unsuitable mounting bore.
• Route the standard coaxial cable away from high-current conductors, switching devices, and other sources of electromagnetic interference.
• Protect the unarmored cable from abrasion, sharp edges, excessive bending, and mechanical impact.
• Ensure the miniature coaxial ClickLoc connector is clean and fully seated before commissioning the measurement channel.
• Verify probe polarity, cable continuity, and connection to the compatible Bently Nevada signal-conditioning electronics.
• Set and verify the probe gap according to the applicable Bently Nevada installation procedure and target geometry.
• Validate the resulting DC output and machine measurement channel before enabling protection or monitoring logic.
• Do not introduce additional cable length or substitute cable types without confirming compatibility with the complete proximity measurement system.
