Bently Nevada 330103-02-12-05-02-CN 3300 XL 8 mm Proximity Probe

Description

Unarmored metric probe configuration 330103-02-12-05-02-CN features a partially threaded M10 x 1 case with a 20 mm unthreaded length (Option 02), a 120 mm overall case length (Option 12), and a short 0.5-meter total cable length (Option 05) terminated with a miniature ClickLoc coaxial connector (Option 02). This configuration is certified under the -CN China hazardous area approval package, integrating NEPSI and CCC safety designations for machinery monitoring applications within regulated Chinese industrial environments.

Unlike armored variants or configurations with integrated connector protectors, this probe uses a standard unarmored 75-ohm triaxial cable with a direct ClickLoc coaxial connection. This makes it suitable for compact mounting spaces where rigid conduit or internal machine routing is already present. The short 0.5-meter probe length is designed for direct coupling with a matching 3300 XL standard extension cable to achieve a total system length of 5.0 or 9.0 meters. In this configuration, it functions within a transducer chain to monitor dynamic shaft vibration, axial position, and speed references on high-speed rotating industrial machinery such as turbines, compressors, and gearboxes.

Features

• Base Configuration: 3300 XL 8 mm metric probe (M10 x 1 thread) without mechanical protective armor.
• Unthreaded Length (Option 02): 20 mm of unthreaded body to accommodate specific bracket recess requirements.
• Overall Case Length (Option 12): 120 mm fully machined steel case for deep-reach housing mountings.
• Total Cable Length (Option 05): 0.5 meter (1.6 feet) total probe lead, minimizing excess cable near the target.
• Connection Interface (Option 02): Miniature ClickLoc coaxial connector without connector protector.
• Cable Construction: Standard 75-ohm triaxial fluorinated ethylene propylene (FEP) insulated cable.
• Agency Approval Suffix (-CN): Pre-certified China hazardous area approval package featuring CCC and NEPSI explosion-proof markings.

Applications

• Dynamic shaft vibration and axial position measurements in rotating machinery.
• Continuous monitoring of industrial turbines, generators, centrifugal compressors, and high-speed pumps.
• Use in Chinese industrial plants and refineries requiring strict NEPSI and CCC explosion-protection certifications.
• Mounting arrangements inside machine casings where external conduit is utilized instead of flexible steel armor.

Installation Guidelines

• Thread Limits: Ensure that thread engagement does not exceed 15 mm during installation into the mounting bracket or machine housing to prevent binding.
• Torque Management: Tighten the probe case to the recommended torque of 7.5 N-m (66 in-lbf). Do not exceed the maximum rating of 22.6 N-m (200 in-lbf) to avoid damage to the metric threads.
• Cable Routing: Observe the minimum cable bend radius of 25.4 mm (1.0 in) along all sections of the FEP insulated lead to protect triaxial shielding integrity.
• Total System Matching: Match this 0.5-meter probe only with standard extension cables and 3300 XL Proximitor sensors designed for 5-meter or 9-meter total system lengths.

Compliance and Certifications

• NEPSI: Certified for explosion-proof and dust ignition-proof atmospheres in the People's Republic of China.
• CCC: China Compulsory Certification for electrical safety and explosion protection.
• Hazardous Area Standard: Approved for Zone 0, Zone 1, and Zone 2 installations when connected via approved barriers to matching Proximitor systems.
