Frequently Asked Questions (FAQ)

Q: Is this a genuine Bently Nevada 3300 XL long probe?
A: Yes. We supply only 100% new and original Bently Nevada products, including this 330101-00-79-10-02-CN.

Q: What is the primary application for this long-case probe?
A: The 7.9-inch overall case length (Option 79) is designed for mounting through thick bearing housings, casings, or any application requiring extended reach to the measurement target.

Q: Does the longer case affect the electrical performance?
A: No. The electrical specifications, including resistance, sensitivity, and linear range, remain identical to standard-length 3300 XL 8mm probes.

Q: What connector type is fitted to this model?
A: This model is configured with a Miniature coaxial ClickLoc connector (Option 02) and a standard cable.

Q: Is the FluidLoc cable option available for this long probe?
A: Yes. The optional FluidLoc cable can be specified to prevent fluid migration along the cable interior in oily environments.

Q: How should I set the gap for this probe in a vibration application?
A: For standard radial vibration monitoring, set the initial mechanical gap to achieve a -9 Vdc output, which is approximately 1.27 mm (50 mils) from the target.
