Product Overview

The Bently Nevada 330106-05-30-90-02-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 features an extra long 9.0 meter cable. This long cable eliminates the need for extension cables in many installations. Its PPS tip and stainless steel body resist wear, heat, and corrosion. This model includes country-specific (CN) agency approval.

Technical Specifications

The 330106-05-30-90-02-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.

Long Cable Advantage

The 330106-05-30-90-02-CN offers a 9.0 meter integrated cable. This length reaches most proximitors directly without extension cables. Fewer connections mean lower signal loss and higher reliability. This design reduces installation time and minimizes potential failure points. The long cable suits large machinery where the proximitor mounts far from the probe.

Installation Guide

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

1. Plan the cable routing path before mounting the probe.

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

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

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

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

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

7. Route the 9.0 meter cable away from moving parts and high heat sources.

8. Connect the Miniature ClickLoc connector firmly to the proximitor.

9. Verify the probe gap voltage through your monitoring system.

Important: Secure the long cable with proper clamps every 30 cm. This prevents cable whip from vibration damage.

Frequently Asked Questions (FAQ)

Q1: Which machines commonly use the 330106-05-30-90-02-CN long cable probe?
A1: This probe suits large turbines, compressors, and generators. The long cable reaches distant proximitors on big industrial machinery.

Q2: Do I need an extension cable with this 9.0 meter probe?
A2: No. The 9.0 meter cable connects directly to most proximitors. This eliminates extension cable costs and connection points.

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 the long cable gets damaged during installation?
A4: You must replace the entire probe assembly. The cable is permanently attached to the probe tip. Handle the cable with care during routing.

Q5: How does humidity affect the 3300 XL 8 mm Reverse Mount Probe with long cable?
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 330106-05-30-90-02-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. The 9.0 meter cable offers flexibility but requires careful handling to avoid kinks and crush damage.
