Product Overview

The Bently Nevada 330106-05-30-10-02-05 is a 3300 XL 8 mm reverse mount probe. This probe features M10 x 1 threads for metric mounting applications. The 330106-05-30-10-02-05 comes with a 1.0 metre (3.3 feet) total length. Engineers use this reverse mount probe for shaft vibration and position monitoring. Additionally, the probe carries CSA, ATEX, and IECEx approvals (option 05). Therefore, it suits hazardous area installations worldwide. The reverse mount design allows installation from outside the machine case.

Technical Specifications

Thread & Mounting Details

The Bently Nevada 330106-05-30-10-02-05 uses M10 x 1 metric threads. This thread size suits European and Asian machine standards. The maximum length of thread engagement is 15 mm . Consequently, you can adjust the probe depth within this range. Tighten the probe locknut to secure the position. Do not exceed the thread engagement limit to avoid damage.

Cable & Connector Specifications

This probe includes a 1.0 metre (3.3 feet) total length. The standard cable uses 75Ω triaxial construction with FEP insulation. FEP stands for fluoroethylene propylene, a durable material. The connector option 02 provides a miniature ClickLoc coaxial connector. This gold-plated connector ensures reliable signal transmission. The connector locks securely to extension cables without tools.

Electrical Characteristics

The nominal probe DC resistance (RPROBE) measures 7.59 Ω ± 0.50 . This resistance applies from the center conductor to the outer conductor. Therefore, you can verify probe integrity with an ohmmeter. Significant deviation from this range may indicate cable damage. Always check resistance before installation.

Agency Approvals

Option 05 provides CSA, ATEX, and IECEx approvals . Therefore, the 330106-05-30-10-02-05 meets global hazardous area requirements. Use this probe in Zone 1, Zone 2, Division 1, or Division 2 locations. Contact Bently Nevada for specific certificate numbers and conditions of use.

Materials & Construction

The probe tip uses Polyphenylene Sulfide (PPS) for durability. The probe case uses AISI 303 or 304 stainless steel (SST) . Both materials resist corrosion and mechanical stress. The connector uses gold-plated brass or gold-plated beryllium copper. Consequently, the probe withstands harsh industrial environments.

Cable Options & Armor

The standard cable uses 75Ω triaxial with FEP insulation. For extended temperature ranges, PFA insulation is available upon request. Optional armor uses flexible AISI 302 or 304 SST with an FEP outer jacket. This probe model comes without armor as standard.

Tensile Strength Ratings

The maximum rated tensile strength between probe case and probe lead is 330 N (75 lbf) . Between the probe lead and extension cable connectors, the rating is 270 N (60 lbf) . Therefore, avoid pulling on the cable during installation. Excessive force may damage internal connections.

Weight

The probe weighs 323 grams per metre (11.4 oz per metre) . For the 1.0 metre version, total weight is approximately 0.32 kg. This lightweight design simplifies handling and installation.

Temperature Range

The standard probe operates from -52°C to +177°C (-62°F to +350°F) . However, exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. For higher temperature applications, use the extended temperature range probe. That version reaches +218°C (+425°F) at the tip and +260°C (+500°F) at the cable.

Pressure Seal Information

The 3300 XL 8 mm probes use a Viton® O-ring to seal differential pressure. This seal sits between the probe tip and the probe case. Notably, Bently Nevada does not pressure test probes prior to shipment. Therefore, contact the custom design department if your application requires pressure seal testing.

Humidity Performance

The probe shows less than a 3% change in Average Scale Factor (ASF) when tested at 93% humidity. This testing follows IEC standard 68-2-3 for up to 56 days . Consequently, the probe performs reliably in humid environments. Condensation inside the connector may still affect signals.

Installation Guide

Follow these steps to install the Bently Nevada 330106-05-30-10-02-05 correctly. First, verify the mating threads on your machine case are M10 x 1. Second, clean the mounting hole thoroughly. Third, apply anti-seize compound to the probe threads to prevent galling.

Fourth, screw the probe into the mounting hole by hand. Turn until the probe tip approaches the target shaft. Fifth, set the air gap to 1.27 mm (50 mils) using a depth gauge or micrometer. Sixth, tighten the locknut to 39.3 N·m (350 in·lb) .

Seventh, connect the miniature ClickLoc connector to your extension cable. Push and twist clockwise until it clicks securely. Eighth, route the cable away from hot surfaces and moving parts. Finally, verify the DC resistance measures 7.59 Ω ± 0.50 between center and outer conductors.

Frequently Asked Questions (FAQ)

1. What thread size does the 330106-05-30-10-02-05 use?
The probe uses M10 x 1 metric threads . The maximum thread engagement length is 15 mm . Therefore, ensure your machine case has matching M10 x 1 threads.

2. What approvals does the 330106-05-30-10-02-05 carry?
Option 05 provides CSA, ATEX, and IECEx approvals for hazardous areas. Consequently, you can install this probe in Zone 1, Zone 2, Division 1, or Division 2 locations. Verify local regulations before installation.

3. Is the 330106-05-30-10-02-05 pressure tested before shipment?
No, Bently Nevada does not pressure test probes prior to shipment. The probe uses a Viton® O-ring for sealing. Contact the custom design department if you require pressure seal testing for your application.

4. What is the DC resistance of this probe?
The nominal probe DC resistance (RPROBE) is 7.59 Ω ± 0.50 . Measure between the center conductor and outer conductor. Significant deviation may indicate cable damage.

5. Can I use this probe with a 3300 XL extension cable?
Yes, the miniature ClickLoc connector mates with standard 3300 XL extension cables. The total system length (probe plus extension) must not exceed 305 metres (1,000 feet) for full frequency response. Extension cables are sold separately.
