Technical Specifications

The Bently Nevada 330106-05-30-30-02-05 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 8.17 ± 0.50 Ω from center to outer conductor for the 3.0 meter length.

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: 3.0 meters (9.8 feet) for long routing paths.

• Connector Type: Miniature ClickLoc coaxial connector (option 02).

• Agency Approvals: 05 = CSA, ATEX, IECEx for hazardous locations.

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.

Hazardous Area Certifications

This 330106-05-30-30-02-05 model carries multiple international approvals. The CSA certification covers North American hazardous locations. The ATEX approval allows use in European explosive atmospheres. The IECEx certification provides global acceptance for mining and industrial gas risks. Please verify your specific zone requirements before installation.

Environmental and Operating Ranges

• Tensile Strength (Lead to Connector): 270 N (60 lbf) at probe lead to extension cable connectors.

• Connector Material: Gold-plated brass or gold-plated beryllium copper.

• Probe Weight: 323 g per meter (11.4 oz per meter) - total approximately 969 grams.

Installation Guidelines

Follow these steps to install your Bently Nevada 330106-05-30-30-02-05 probe correctly in hazardous areas.

1. Verify Area Classification – Confirm your zone matches the CSA, ATEX, or IECEx certification.

2. Use Proper Isolation – Install a certified barrier between the probe and the monitoring system.

3. Inspect the Probe – Check for any shipping damage on the PPS tip and threads.

4. Clean the Mounting Hole – Ensure the M10 x 1 threaded hole is clean and dry.

5. Hand-Thread First – Turn the probe case by hand for two to three rotations to avoid cross-threading.

6. Torque to Specification – Tighten the probe case to 6.8 to 8.5 N·m (60 to 75 in-lb).

7. Connect the Cable – Secure the miniature ClickLoc connector until it clicks firmly.

8. Route the 3.0m Cable – Keep the triaxial cable away from high voltage and heat sources.

9. 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. For hazardous area installations, follow all local electrical codes.

Frequently Asked Questions (FAQ)

1. Which hazardous area certifications does the 330106-05-30-30-02-05 hold?
This probe holds CSA, ATEX, and IECEx certifications. These approvals cover gas, vapor, and dust explosive environments in most global regions.

2. Does the 3.0 meter cable length affect signal quality?
No. The 3300 XL series maintains excellent signal integrity up to 9 meters total length. The 3.0 meter length works well with standard extension cables.

3. Can I use this certified probe without hazardous area barriers?
No. You must install proper isolation barriers between the probe and the monitor. The barrier limits energy entering the hazardous zone.

4. 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.

5. Is this probe compatible with older Bently Nevada monitors?
Yes. The 330106-05-30-30-02-05 works with 3300, 3500, and 1900 series monitoring systems. Check the system's input impedance before connection.

6. 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.
