Technical Specifications
The Bently Nevada 330106-05-30-15-02-CN uses a Polyphenylene sulfide (PPS) probe tip. This material offers excellent chemical and wear resistance. The probe case uses AISI 303 or 304 stainless steel (SST) for strong durability. You get a nominal probe DC resistance of 7.73 ± 0.50 Ω from center to outer conductor.
Key Electrical and Mechanical Parameters
Thread Type: M10 x 1 threads for secure mounting.
Thread Engagement Length: Maximum 15 mm for stable installation.
Total Length Option: 1.5 meter (4.9 feet) for flexible routing.
Connector Type: Miniature ClickLoc coaxial connector (option 02).
Agency Approval: CN (Country Specific) for regional compliance.
The probe cable uses 75Ω triaxial design with FEP insulation. This setup provides strong protection against electrical noise. You can trust the 3300 XL 8 mm probe for accurate readings in harsh environments.
Environmental and Operating Ranges
Probe Temperature (Standard): -52°C to +177°C (-62°F to +350°F).
Probe Tip Temperature (Extended): Up to +218°C (+425°F).
Cable Temperature (Extended): -51°C to +260°C (-60°F to +500°F).
Relative Humidity: Less than 3% change in ASF at 93% humidity for 56 days (IEC 68-2-3).
Pressure Seal: Viton® O-ring seals differential pressure between tip and case.
⚠️ Important Note: Exposing this probe below -34°C (-30°F) may cause early pressure seal failure. Please follow proper installation guidelines.
Mechanical Strength
Tensile Strength (Case to Lead): 330 N (75 lbf).
Tensile Strength (Lead to Connector): 270 N (60 lbf).
Connector Material: Gold-plated brass or gold-plated beryllium copper.
Probe Weight: 323 g per meter (11.4 oz per meter).
Installation Guidelines
Follow these steps to install your Bently Nevada 330106-05-30-15-02-CN probe correctly.
Inspect the Probe – Check for any shipping damage on the PPS tip and threads.
Clean the Mounting Hole – Ensure the M10 x 1 threaded hole is clean and dry.
Hand-Thread First – Turn the probe case by hand for two to three rotations to avoid cross-threading.
Torque to Specification – Tighten the probe case to 6.8 to 8.5 N·m (60 to 75 in-lb).
Connect the Cable – Secure the miniature ClickLoc connector until it clicks firmly.
Route the Cable – Keep the triaxial cable away from high voltage and heat sources.
Verify Air Gap – Use a 3300 XL proximity system to confirm the correct gap voltage.
Do not twist the probe cable beyond its natural bend radius. A sharp bend will damage the internal conductor.

Frequently Asked Questions (FAQ)
1. What machines work best with the Bently Nevada 330106-05-30-15-02-CN?
This probe suits steam turbines, gas turbines, compressors, and large pumps. It measures radial vibration and axial position reliably.
2. Can I use an extension cable with this 3300 XL probe?
Yes. This probe works with Bently Nevada 3300 XL extension cables. Use a compatible junction box and connector for proper signal integrity.
3. How does the reverse mount design help my installation?
The reverse mount allows you to insert the probe from the machine's interior. This feature saves space where external probe access is limited.
4. Is this probe compatible with older Bently Nevada monitors?
Yes. The 330106-05-30-15-02-CN works with 3300, 3500, and 1900 series monitoring systems. Check the system's input impedance before connection.
5. What happens if I expose the probe to high humidity for months?
The probe maintains less than 3% scale factor change after 56 days at 93% humidity. Long-term high humidity may still require periodic calibration checks.
