Bently Nevada 330106-05-30-05-12-00 Reverse Probe

Bently Nevada 330106-05-30-05-12-00 3300 XL 8 mm Reverse Mount Probe

Product Introduction

The Bently Nevada 330106-05-30-05-12-00 belongs to the 3300 XL series of 8 mm reverse mount proximity probes. This specific configuration includes M10X1 threads and a 0.5-meter total cable length. Additionally, it features a miniature ClickLoc coaxial connector with FluidLoc cable for secure and reliable connections.

This probe utilizes a Polyphenylene sulfide (PPS) tip and an AISI 303 or 304 stainless steel case. Therefore, it offers excellent durability and corrosion resistance for demanding industrial applications. Moreover, the 3300 XL series is fully compliant with the American Petroleum Institute (API) 670 Standard for machinery protection. Consequently, the 3300 XL 8 mm probe is an ideal choice for critical turbomachinery monitoring in power generation, oil and gas, and petrochemical facilities.

Mechanical and Environmental Parameters

The 3300 XL 8 mm Reverse Mount Probe features a rugged mechanical design for harsh operating conditions. The probe case material is either AISI 303 or 304 stainless steel, providing excellent strength and corrosion resistance. Additionally, the connector uses gold-plated brass or gold-plated beryllium copper for reliable signal transmission.

For temperature performance, 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) for a sustained period may cause premature pressure seal failure. The probe incorporates a Viton O-ring to seal differential pressure between the tip and the case. Furthermore, the probe demonstrates excellent humidity resistance, with less than a 3% change in Average Scale Factor (ASF) when tested in 93% humidity for up to 56 days per IEC standard 68-2-3.

Key Features and Benefits

The Bently Nevada 3300 XL probe series offers several distinct advantages for machinery protection applications. First, the patented TipLoc molding method creates a robust bond between the probe tip and the probe body. This significantly enhances mechanical strength and prevents tip separation.

In addition, all connector components feature gold-plated surfaces for superior conductivity and corrosion resistance. The ClickLoc connector locks firmly into place and effectively prevents loosening due to vibration. Meanwhile, the FluidLoc cable option provides additional protection against fluid ingress along the cable. However, the FluidLoc option is not necessary for the vast majority of 330105 and 330106 installations due to the presence of the probe sleeve. Therefore, you should carefully consider your application before ordering this option.

Installation Guidelines

Proper installation is essential for achieving optimal performance from the 330106-05-30-05-12-00 probe.

First, verify that the mounting thread is M10X1 and that the maximum thread engagement is 15 mm. Next, ensure the target surface is clean, smooth, and within the probe's linear range. Then, set the gap according to your specific application requirements, typically between -1 and -13 Vdc output.

After that, route the 0.5-meter cable carefully to avoid sharp bends or mechanical stress. Connect the miniature ClickLoc connector by pushing it firmly until it clicks securely into place. Finally, use shielded triad cable for field wiring and observe the maximum cable length limits specified by the monitoring system.

Packaging List

The 330106-05-30-05-12-00 unit is shipped new and original in factory packaging. The package contains the following items:

• 1 x Bently Nevada 3300 XL 8 mm Reverse Mount Probe (M10X1 thread).

• 1 x 0.5 m probe cable with miniature ClickLoc coaxial connector (FluidLoc cable).

Frequently Asked Questions (FAQ)

1. What is the difference between the 330105 and 330106 probe models?
The primary difference lies in the thread type. The 330106 model features M10X1 threads, while the 330105 model uses 3/8-24 UNF threads. Therefore, you should select the model that matches your mounting hardware.

2. Do I really need the FluidLoc cable option for this probe?
The FluidLoc cable option (Suffix 12) is not necessary for the vast majority of 330106 installations due to the presence of the probe sleeve. However, you should consider this option if your application involves significant fluid ingress risk.

3. What is the recommended torque for installing this probe?
For the 3300 XL 8 mm probe, you should follow the torque specifications provided in the installation manual. Typically, you should tighten the probe case to the recommended value and avoid exceeding the maximum rated torque to prevent damage.

4. What shipping methods do you use for this item?
We ship this product using major international couriers. The shipping methods are typically Fedex, UPS, or DHL to ensure fast and reliable delivery worldwide.

5. Is this probe pressure tested prior to shipment?
The 3300 XL 8 mm probes are not pressure tested prior to shipment. However, they are designed to seal differential pressure between the probe tip and case using a Viton O-ring. If you require pressure seal testing for your specific application, you should contact the custom design department.
