Bently Nevada 330106-05-30-10-02-CN Reverse Mount Probe

3300 XL 8mm M10x1 Reverse Probe 1m – Bently Nevada

Product Introduction

The Bently Nevada 330106-05-30-10-02-CN belongs to the 3300 XL 8 mm Reverse Mount Probes family. This probe measures shaft vibration and position in tight machinery spaces. Its reverse mounting design allows installation where standard probes cannot fit. The M10x1 thread provides a secure mounting option for metric systems.

Additionally, this model features a 1.0-meter (3.3 feet) total length. The Miniature ClickLoc coaxial connector ensures reliable signal transmission. The probe tip uses Polyphenylene sulfide (PPS) , while the case uses AISI 303 or 304 stainless steel. These materials deliver excellent durability in harsh industrial environments.

Furthermore, the CN Agency Approval covers hazardous area certifications. You can use this probe in Class I, Zone 0 and Class I, Division 2 locations. Its temperature range spans from -52°C to +177°C for standard applications.

Mechanical and Environmental Parameters

Pressure Sealing

The 3300 XL 8 mm probes seal differential pressure between the probe tip and case. A Viton® O-ring provides this sealing function. However, Bently Nevada does not pressure test these probes before shipment. For applications requiring a pressure seal test, contact their custom design department.

Humidity Performance

This probe passes the IEC 68-2-3 humidity test. It shows less than a 3% change in Average Scale Factor (ASF) after 56 days at 93% relative humidity. This stability ensures reliable readings in humid environments.

Tensile Strength Considerations

The 330106 probe handles up to 330 N of pull force between the case and probe lead. Additionally, the connection point between probe lead and extension cable withstands 270 N. Never exceed these limits during installation or maintenance.

Installation Guidelines

First, verify your mounting hole uses M10x1 metric threads. Next, ensure thread engagement does not exceed 15 mm. Over-tightening can damage the probe or the pressure seal.

For hazardous area installations, follow drawing 141092 for intrinsic safety circuits. Alternatively, use drawing 140979 for non-incendive circuits. Pay close attention to ambient temperature limits based on your T-classification.

The Miniature ClickLoc connector provides a secure coaxial connection. Its gold-plated contacts resist corrosion and maintain signal integrity. The 1.0-meter (3.3 feet) total length works well for short-distance installations where the monitoring system sits close to the measurement point.

Frequently Asked Questions (FAQ)

1. What thread size does the Bently Nevada 330106-05-30-10-02-CN use?
This model uses M10x1 metric threads. The maximum recommended thread engagement length is 15 mm. Always match this thread specification with your mounting hardware.

2. Can I order this probe with a longer cable?
Yes, the 3300 XL 8 mm Reverse Mount Probes series offers total lengths of 0.5, 1, 1.5, 2, 3, 5, and 9 meters. The -10 option in this product number indicates 1.0 meter. Choose a different suffix for longer cables.

3. What is the PPS tip material used for?
Polyphenylene sulfide (PPS) provides excellent chemical resistance and dimensional stability. It withstands high temperatures and harsh industrial environments without degrading.

4. Is pressure testing available before shipment?
Standard units do not receive pressure testing. However, you can contact Bently Nevada's custom design department to request a pressure seal test for your specific application.

5. What happens if I operate this probe below -34°C?
Operating below –34°C (-30°F) may cause premature failure of the Viton® O-ring pressure seal. Always stay within the specified -52°C to +177°C range for standard operation.
