Description

The Bently Nevada 330104-00-03-10-01-00 is an industrial-grade, heavy-duty 3300 XL 8 mm proximity probe designed to monitor shaft vibration and position on fluid-film bearing machines. This specific model is configured with metric M10 x 1 threads and integral stainless steel armor, providing rugged physical shielding for triaxial cables exposed to harsh, abrasive, and cutting-prone industrial environments. Unlike unarmored or imperial-threaded probe variations, this metric model has a 30 mm case length (B Option: 03) and 0 mm of unthreaded length (A Option: 00), making it ideal for compact metric mounting holes where maximum thread engagement and adjusting range are required. It operates on the eddy current measurement principle, establishing a linear, highly accurate measurement system when combined with a standard 3300 XL extension cable and Proximitor sensor. Equipped with a 1.0-meter (3.3 ft) total length and a Miniature coaxial ClickLoc connector with an integrated connector protector (Option 01), this configuration physically seals critical connections from turbine oil, moisture, and debris. Lacking hazardous area agency approvals (E Option: 00), this probe serves as a reliable, high-performance solution for standard machinery monitoring in safe industrial areas.

Features

• Integral SST Armor: Flexible AISI 302 or 304 stainless steel armor with an outer FEP jacket shields the probe cable from physical cuts, abrasion, and mechanical abuse.
• Connector Protector (Option 01): Mated miniature coaxial ClickLoc connector features an integrated protector sleeve that seals out industrial oil, water, and contaminants.
• Full Case Threading: Configured with 0 mm of unthreaded length (A: 00) on a 30 mm case (B: 03), maximizing installation flexibility in metric M10 x 1 ports.
• High-Durability Probe Tip: Molded polyphenylene sulfide (PPS) tip resists chemical deterioration, moisture, and high temperatures.
• FEP Coaxial Cable: Standard 75 ohm triaxial cable insulated with fluoroethylene propylene (FEP) ensures signal integrity under high-temperature conditions.

Applications

• Industrial steam turbines, gas turbines, and generators.
• High-speed centrifugal and axial compressors.
• Process gearboxes and fluid-film bearing machinery.
• Rotor dynamic shaft vibration and axial thrust position tracking.
• Keyphasor phase reference and shaft rotational speed measurements.

Ordering Information

The Bently Nevada 330104-00-03-10-01-00 is a precise configuration. The table below decodes this specific orderable SKU based on the official 3300 XL 8 mm Metric Proximity Probe selection guidelines:

Connections and Interfaces

Installation Guidelines

To avoid signal distortion or mechanical failure during probe replacement, observe the following procedures:

• Installation Torque: Do not exceed the maximum rated thread torque of 22.6 N-m (200 in-lbf) for forward-mounted metric probes in matching tapped ports. The recommended installation torque is 7.5 N-m (66 in-lbf).
• Maximum Thread Engagement: Thread engagement in metric M10 x 1 threaded holes must not exceed 15 mm to prevent thread binding.
• Probe Air Gap: Calibrate and shim the probe air gap to approximately 1.27 mm (50 mils) to establish standard midpoint calibration (-10 Vdc on 3300 XL Proximitor systems).
• Routing of Armored Lead: Ensure the armored cable is routed with a bend radius of no less than 25.4 mm (1.0 in) to prevent damaging coaxial conductors under the armor.
• Sleeve Protective Seals: Firmly slide the built-in Option 01 connector protector over the coaxial connection. Do not apply silicone tape for turbine oil exposure.

Compliance and Certifications

This Bently Nevada probe configuration meets standard industrial machinery requirements:

• CE Mark: Fully compliant with European Union Directives, including EMC and Machinery Safety Directives.
• RoHS: Compliant with the Restriction of Hazardous Substances Directive.
• China Hazardous Area Approval (-CN): Not applicable. Since this SKU is ordered with Option E: 00 (Agency Approval Option: Not required), it does not possess explosion-proof or intrinsic safety certificates on the label. For applications requiring NEPSI, CCC, or other localized China hazardous area compliance, specify the -CN suffix variant or select Option E: 05.
