Bently Nevada 330106-05-30-30-02-00 8mm Reverse Probe

Bently Nevada 330106-05-30-30-02-00 3300 XL 8 mm Reverse Mount Probe

Product Introduction

The Bently Nevada 330106-05-30-30-02-00 is part of the widely used 3300 XL series. This 8 mm reverse mount probe delivers non-contact displacement and vibration measurements. Many facilities choose this 3300 XL probe for turbines, compressors, and large pumps.

This model 330106-05-30-30-02-00 comes with a 3.0-meter total cable length. Its M10x1 thread fits standard mounting holes without modifications. Furthermore, the Miniature ClickLoc coaxial connector ensures a reliable and fast connection. This reverse mount probe operates effectively in general-purpose industrial environments.

Since this version has approval option 00, it does not carry ATEX or IECEx certifications. Therefore, it is ideal for non-hazardous areas where explosive gases or dust are not present. Nevertheless, it maintains the same rugged build quality as the certified versions. The PPS tip and SST case deliver excellent durability and chemical resistance.

Technical Specifications

The Bently Nevada 330106-05-30-30-02-00 offers stable electrical characteristics. The nominal probe resistance (RPROBE) from center to outer conductor measures 8.17 Ω ± 0.50 at 3.0 meters. This precise value ensures consistent output to your proximity monitoring system.

The probe uses a 75Ω triaxial cable with FEP insulation as standard. For higher temperature applications, you can order PFA-insulated cable. Standard cable lengths available include 0.5, 1, 1.5, 2, 3, 5, or 9 meters. Additionally, optional flexible armor is available with an AISI 302/304 SST and FEP jacket.

Gold-plated brass or beryllium copper forms the connector material. This plating reduces signal loss and prevents oxidation. The tensile strength rating is 330 N (75 lbf) from case to lead, and 270 N (60 lbf) at the lead-to-extension connector. These ratings provide confidence during installation and long-term use.

Mechanical and Environmental Ratings

The probe case uses an M10x1 thread with a maximum engagement length of 15 mm. The unit weighs 323 g per meter (11.4 oz/m), which makes handling and installation straightforward.

For temperature performance, this standard 3300 XL probe operates from -52°C to +177°C (-62°F to +350°F). If you need higher temperature resistance, the extended range version supports up to +218°C (+425°F) at the tip and +260°C (+500°F) for the cable. Remember that operating below -34°C (-30°F) may compromise the pressure seal.

The pressure seal uses a Viton® O-ring to block differential pressure. Although each probe is not pressure-tested before shipping, you can request custom testing. Meanwhile, humidity testing confirms less than 3% ASF change after 56 days at 93% relative humidity, following IEC 68-2-3 standards.

Installation Guidelines

Proper installation of the Bently Nevada 330106-05-30-30-02-00 ensures optimal performance. Follow these steps carefully:

• Thread inspection : Clean the M10x1 mounting hole and verify its depth with a thread gauge.

• Cable management : Avoid tight bends near the connector. Keep a minimum bend radius of 50 mm.

• Torque application : Tighten the probe to 20–30 N·m. Excessive force may damage the threads.

• Connector engagement : Align the Miniature ClickLoc connector and push until you hear a click. Then test the lock by a gentle pull.

• Cable support : Use cable ties every 300 mm to prevent chafing from vibration.

After mounting, set the air gap between the probe tip and the target surface. A typical gap ranges from 1.5 mm to 2.5 mm. Use a calibrated proximity meter to adjust the initial voltage. Finally, perform a run-out test before starting your machinery.

Frequently Asked Questions

1. Is this 330106-05-30-30-02-00 compatible with Bently Nevada extension cables?
Yes, the Bently Nevada 330106-05-30-30-02-00 uses the standard Miniature ClickLoc connector. It works with all Bently Nevada extension cables that have the same connector type.

2. What is the total system length I can achieve with this reverse mount probe?
You can extend it up to 9 meters using approved extension cables. However, ensure the combined length stays within the driver’s calibration range for accurate readings.

3. Can I replace the probe tip if it becomes damaged?
No, the tip is not replaceable separately. You must replace the entire 3300 XL probe unit if the tip is worn or broken.

4. How should I clean the probe tip without causing damage?
Use a soft cloth with isopropyl alcohol. Avoid abrasive pads or harsh solvents that could scratch the PPS surface. Allow it to dry fully before reinstallation.

5. Why does this version have no agency approvals (00)?
The approval option 00 means this probe does not carry ATEX, CSA, or IECEx certifications. It is designed for non-hazardous locations where explosive atmospheres are not present.
