Extra-Long 8mm Probe for Deep or Insulated Installations
Meet the Bently Nevada 330101-00-63-10-02-00. This is an extended-length 3300 XL 8mm Proximity Probe. It features a fully threaded 6.3-inch body for significant reach. This probe solves clearance issues with thick insulation, deep bearing housings, or complex machinery frames. It delivers reliable vibration data where standard probes cannot reach.
Why You Need This Long-Reach Probe
- Exceptional Reach for Tough Spots: The 6.3-inch case length (-63 suffix) allows mounting through deep cavities or thick thermal insulation blankets.
- Fully Threaded for Stability: Threads run the entire case length (00 suffix). This provides maximum grip and prevents loosening from vibration.
- Superior 8mm Durability: Even at this length, the 8mm stainless steel body maintains high stiffness and resists bending.
- Secure, Vibration-Proof Cable: The CableLoc system ensures the cable connection stays intact, critical for long-term reliability in vibrating equipment.
- Broad Temperature Capability: Operates reliably from -52°C to +177°C, suitable for both cold and hot external environments.

Installation Guide for Long Probes
- This probe is designed for applications where the measurement point is far inside the machine casing.
- Ensure your mounting hole is deep enough and has clean, full-depth 3/8-24 UNF threads to support the probe.
- Due to the length, handle with care to avoid bending. Support the probe body during installation.
- Thread engagement in the mounting part must not exceed 0.563 inches to avoid stress.
- Always use a torque wrench on the hex flats. Apply 100 in-lbf (11.2 N•m) as recommended.
- Fully compatible with the Bently Nevada 3300 XL monitoring system. No special setup required.
- During inspections, check for any signs of the probe body rubbing on adjacent parts.

Specialized FAQs for Long Probes
When should I choose a 6.3-inch probe over a standard length?
Select this probe when you need to mount through over 4 inches of material, such as a metal casing plus a thick layer of thermal or acoustic insulation.
Does the long length affect the probe’s sensitivity or performance?
No. The sensing tip and electrical characteristics are identical to standard probes. The longer mechanical body does not change the output signal or linearity.
How do I prevent a long probe from vibrating or resonating?
Ensure it is fully threaded into a rigid mounting boss. The fully threaded design (-00) provides excellent damping. Avoid unsupported spans where the probe is exposed.
Can I get this long probe with hazardous area certifications?
Yes. You would need to order a variant with the approval suffix -05 instead of -00. For example: 330101-00-63-10-02-05.
What is the best practice for shipping and handling such a long probe?
We pack it securely to prevent bending. Upon receipt, store it horizontally or supported along its length. Do not let it protrude unsupported from a bench where it could be knocked over.
