Product Overview

The Bently Nevada 330105-02-12-10-02-CN represents the specialized Reverse Mount configuration of the industry-standard 3300 XL 8mm Proximity Probe series. This eddy current sensor facilitates non-contact shaft vibration and displacement measurements in environments where traditional forward-mounting is physically impossible. The reverse mount design allows technicians to install the probe into a housing or bracket from the rear, making it ideal for tight machine clearances. We supply this unit as 100% New and Original, featuring the -CN specific agency approvals for hazardous area compliance.

Technical Specifications

Engineering Advantages

• Optimized for Confined Spaces: The reverse mount architecture solves the "internal access" problem. By threading the probe from the outside of a bearing housing into an internal bracket, you eliminate the need for complete machinery disassembly during sensor replacement.

• Superior Linearity: As part of the 3300 XL family, this probe demonstrates exceptional resistance to "cross-talk" and temperature-induced voltage shifts. It maintains a consistent 200 mV/mil scale factor even in fluctuating thermal environments.

• Hazardous Area Compliance: The -CN suffix ensures the probe meets stringent NEPSI requirements for the Chinese market and international ATEX/IECEx standards, allowing safe deployment in explosive gas atmospheres.

• Robust Interconnects: The ClickLoc™ connector system features gold-plated contacts that resist corrosion and mechanical loosening. The 1.0-meter total length (Option -10) provides a standardized footprint for integration with 3300 XL extension cables.

FAQs

When should I choose a Reverse Mount Probe over a Standard Mount?

Select the 330105 Reverse Mount Probe when your machine housing lacks the clearance for a standard probe and bracket setup, or when the installation point is only accessible from the exterior of the machine casing. It is commonly used in specialized gearbox and small-bore bearing applications.

What is the significance of the "CN" approval?

The -CN option indicates that the product carries specific certifications for the Chinese market, typically NEPSI. It ensures the probe meets local safety regulations for hazardous areas, which is mandatory for many oil, gas, and petrochemical projects within China.

Does this probe require a specific Proximitor® sensor?

Yes. You must pair this probe with a 3300 XL Proximitor® Sensor. While the physical mount is different, the electrical characteristics match the 3300 XL 8mm standard, requiring a 5-meter or 9-meter system calibration (based on your extension cable selection).

Can this probe withstand high-pressure environments?

While the 330105 is ruggedized for vibration and temperature, it is not a "pressure-seal" probe. If your application involves high-pressure lubricants or gases, you must use a specialized Bently Nevada pressure-sealed housing or a specific high-pressure probe variant to prevent leakage.
