Product Overview

The Bently Nevada 330106-05-30-30-02-CN belongs to the reliable 3300 XL Series. This reverse mount probe monitors vibration and position in rotating machinery. The 3300 XL 8 mm Reverse Mount Probe delivers stable measurements in harsh industrial environments. Its PPS tip and stainless steel body resist wear, heat, and corrosion. This specific model includes a 3.0 meter total cable length and country-specific (CN) agency approval.

Technical Specifications

The 330106-05-30-30-02-CN uses a Polyphenylene sulfide (PPS) probe tip. This material provides excellent chemical resistance and thermal stability. The probe case comes from AISI 303 or 304 stainless steel (SST). These materials ensure high mechanical strength and a long service life in demanding conditions.

Installation Guide

Follow these steps to install the 3300 XL 8 mm Reverse Mount Probe correctly:

1. Inspect the mounting hole for debris, rust, or damaged threads.

2. Clean the hole using a suitable thread chaser if necessary.

3. Apply a small amount of anti-seize lubricant on the <b>M10 x 1</b> threads.

4. Hand-tighten the probe slowly to avoid cross-threading damage.

5. Use a torque wrench for final tightening. Do not exceed the recommended torque value.

6. Connect the Miniature ClickLoc connector firmly to the extension cable.

7. Verify the probe gap voltage through your proximitor monitoring system.

Important: Keep the probe cable away from high-voltage power cables. This practice reduces electrical noise interference and ensures accurate readings.

Frequently Asked Questions (FAQ)

Q1: Which machines commonly use the 330106-05-30-30-02-CN probe?
A1: This probe monitors vibration in steam turbines, gas turbines, compressors, pumps, and large fans. The 3300 XL Series suits most rotating equipment in power plants and factories.

Q2: Can I use an extension cable with this 3.0 meter probe?
A2: Yes. You can add a Bently Nevada extension cable up to 9 meters. The ClickLoc connector ensures a secure and reliable connection between cables.

Q3: What does the CN agency approval option mean for this probe?
A3: CN indicates country-specific approval for China. This probe meets local regulatory requirements for that region. The performance remains identical to standard models.

Q4: What happens if I expose the probe tip to temperatures above +177°C?
A4: The probe tip may suffer permanent calibration drift or physical damage. The standard probe tip has a maximum rating of +177°C (+350°F). Use the extended temperature version for higher heat applications.

Q5: How does humidity affect the 3300 XL 8 mm Reverse Mount Probe?
A5: Humidity has very little effect on measurement accuracy. The probe passes IEC 68-2-3 testing. The scale factor changes less than 3% after 56 days at 93% relative humidity.

Compliance and Usage Note

This Bently Nevada 330106-05-30-30-02-CN carries agency approval option CN for country-specific requirements. Always follow local safety regulations during installation and operation. Store the probe in a dry environment between -52°C and +177°C. Never pull the probe by its cable. Pull only the connector body or the metal probe case. This practice prevents internal wire damage and extends product life.
