3300 XL 8mm Probe 330106-05-30-05-12-05 | Bently Nevada

330106-05-30-05-12-05 Product Introduction

The Bently Nevada 330106-05-30-05-12-05 belongs to the 3300 XL 8 mm reverse mount probe family with metric M10x1 threading. This configuration differs from the standard 3/8-24 UNF thread found on many probes, making it suitable for installations that require metric mounting hardware. Reverse mount probes install from outside the machine casing inward, simplifying access and maintenance.

This 3300 XL 8 mm reverse mount probe features the same patented TipLoc and CableLoc technologies as other probes in the series. TipLoc creates a stronger bond between the probe tip and body, while CableLoc provides 330 N (75 lbf) pull strength. The 8 mm diameter delivers thicker PPS encapsulation, resulting in enhanced ruggedness and resistance to physical abuse.

Key Technical Specifications

The 330106-05-30-05-12-05 offers a linear range of 2 mm (80 mils), beginning at approximately 0.25 mm (10 mils) from the target. Its Incremental Scale Factor (ISF) is 7.87 V/mm (200 mV/mil) with ±5% interchangeability error. For this 0.5-meter configuration, the nominal DC resistance from center to outer conductor measures 7.45 ± 0.50 Ω.

The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils). This probe uses an M10x1 metric thread with a maximum engagement length of 15 mm. Torque recommendations are not specified in the documentation, so follow standard 3300 XL practice: apply moderate torque while avoiding overtightening.

This model incorporates total length option 05 (0.5 meter / 1.6 feet), connector option 12 (Miniature ClickLoc coaxial connector with FluidLoc cable), and agency approval option 05 (CSA, ATEX, IECEx approvals). The physical dimensions are consistent with standard 8 mm reverse mount probes.

Metric Thread Design and FluidLoc Option

The Bently Nevada 330106-05-30-05-12-05 features M10x1 metric threading. This thread specification is common in European and Asian installations where metric hardware standards prevail. The M10x1 thread provides a coarse pitch of 1 mm, offering secure engagement with matching probe holders and mounting hardware.

The FluidLoc cable option (indicated by -12) prevents oil and other liquids from leaking through the cable's interior. However, Bently Nevada notes that this option is not necessary on the vast majority of 330105 and 330106 installations due to the presence of the probe sleeve. Carefully consider your application requirements before ordering the FluidLoc option.

Environmental and Mechanical Ratings

The 330106-05-30-05-12-05 operates across a wide temperature range. Standard probe tips handle -52°C to +177°C (-62°F to +350°F). Extended temperature range options allow tips to reach +218°C (+425°F) and cables to reach +260°C (+500°F). Remember that temperatures below –34˚C (-30˚F) may cause premature failure of the pressure seal.

The probe case uses AISI 303 or 304 stainless steel with a Polyphenylene sulfide (PPS) tip. A Viton® O-ring seals differential pressure between the tip and case. While probes are not pressure-tested before shipment, you can arrange custom testing through Bently Nevada's design department.

The probe shows less than a 3% change in Average Scale Factor (ASF) after 56 days of 93% humidity testing per IEC standard 68-2-3. Weight is 323 g/m (11.4 oz), totaling approximately 0.35 kg for the 0.5-meter length.

Installation Guidelines

Installing the 330106-05-30-05-12-05 requires attention to the metric M10x1 thread specification. Thread the probe into the casing from the exterior using compatible metric mounting hardware. The maximum engagement length is 15 mm. Apply standard torque values appropriate for M10x1 stainless steel threads.

The 0.5-meter cable provides flexibility for installations where the Proximitor Sensor is located close to the probe. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG), preferably 3-conductor shielded triad cable with tinned wiring. The maximum distance between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet).

For hazardous area installations, strictly follow the associated control drawings (141092 for intrinsic safety, 140979 for non-incendive circuits). Install appropriate zener barriers or galvanic isolators as specified to maintain the safety certification.

Frequently Asked Questions (FAQ)

1. What is the difference between the 330106 and 330105 reverse mount probes?
The primary difference is the thread specification. The 330106-05-30-05-12-05 uses an M10x1 metric thread, while the 330105 series uses a 3/8-24 UNF inch thread. Choose the 330106 for installations requiring metric mounting hardware.

2. Do I need the FluidLoc cable option for this probe?
Bently Nevada states that the FluidLoc option is not necessary for the vast majority of 330105 and 330106 installations due to the probe sleeve. Only order FluidLoc if your specific application involves oil or liquid leakage risks that the sleeve cannot adequately address.

3. What approvals does agency option 05 include?
Option 05 provides CSA, ATEX, and IECEx approvals. This combination covers most international hazardous area requirements, including Class I, Zone 0 (ia) and Zone 2 (nA) certifications.

4. Can I use this probe with extension cables?
Yes, the 330106-05-30-05-12-05 connects to standard 3300 XL extension cables via the Miniature ClickLoc connector. Extension cables are available in various lengths, allowing you to extend the total system length as needed.

5. What is the maximum thread engagement length for M10x1?
The maximum thread engagement length for the M10x1 thread on the 330106-05-30-05-12-05 is 15 mm. Do not exceed this length to avoid damaging the probe case or compromising the mounting integrity.
