Product Overview

The Bently Nevada 330106-05-30-30-12-05 belongs to the trusted 3300 XL Series. This reverse mount probe measures vibration and position in rotating machinery. The 3300 XL 8 mm Reverse Mount Probe features a special FluidLoc cable option. This probe carries CSA, ATEX, and IECEx approvals for hazardous locations. Its PPS tip and stainless steel body ensure long-term reliability in tough environments.

Technical Specifications

The 330106-05-30-30-12-05 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 deliver high mechanical strength and superior corrosion resistance.

Electrical Parameters

• Nominal DC Resistance: 8.17 ± 0.50 Ω (measured from center to outer conductor)

• Cable Impedance: 75Ω triaxial design

• Standard Cable Insulation: Fluoroethylene propylene (FEP)

• Extended Range Cable Insulation: Perfluoroalkoxy (PFA) for higher temperature applications

Special Cable Feature – FluidLoc

The 330106-05-30-30-12-05 includes the FluidLoc cable option (12). This cable prevents fluid wicking along the probe cable. Most standard installations do not need this feature due to the existing probe sleeve. Only order FluidLoc when fluid contamination is a known risk in your application.

These approvals allow safe installation in potentially explosive environments. Always verify local regulations before installation.

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 FluidLoc cable away from sharp edges and high heat sources. This protects the special fluid-blocking layer.

Package List

The original box for 330106-05-30-30-12-05 includes the following items:

• One 3300 XL 8 mm Reverse Mount Probe (3.0 meter FluidLoc cable)

• One pre-attached Miniature ClickLoc coaxial connector

• One protective plastic cap for the probe tip

• One quick start installation guide (printed sheet)

Frequently Asked Questions (FAQ)

Q1: What makes the FluidLoc cable different from a standard cable?
A1: The FluidLoc cable prevents fluid from wicking inside the cable assembly. This protects the connector and proximitor from liquid contamination.

Q2: Do I really need the FluidLoc option on the 330106-05-30-30-12-05?
A2: Most installations do not need FluidLoc. The probe sleeve already provides fluid protection. Only order FluidLoc when fluid exposure is a known risk in your application.

Q3: Which machines commonly use this probe with hazardous area approvals?
A3: This probe monitors vibration in oil refineries, chemical plants, and gas processing facilities. The 3300 XL Series suits rotating equipment in explosive atmospheres.

Q4: Can I use this probe without an extension cable?
A4: Yes. The 3.0 meter cable reaches many proximitors directly. You can add an extension cable if you need more distance.

Q5: What temperatures can the 330106-05-30-30-12-05 withstand?
A5: The probe tip works from -52°C to +177°C (-62°F to +350°F). The cable and connector handle the same range. Do not exceed these limits.

Compliance and Usage Note

This Bently Nevada 330106-05-30-30-12-05 carries agency approvals 05 for CSA, ATEX, and IECEx. These certifications allow safe use in hazardous locations. 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. Consider carefully if the FluidLoc feature is necessary for your specific application before purchasing.
