Bently Nevada 330703-000-060-10-02-CN 3300 XL 11 mm Proximity Probe

Description

Option 000 (0 mm unthreaded length) and Option 060 (60 mm overall case length) specify the metric physical configuration of the 330703-000-060-10-02-CN 3300 XL 11 mm proximity probe. This unarmored probe has a 1.0 m total length (Option 10) and is equipped with a miniature coaxial ClickLoc connector with standard cable (Option 02). This configuration is certified under the -CN China hazardous area approval package, providing NEPSI and CCC certifications for industrial safety compliance in regulated zones.

Compared to standard imperial variants with 1/2-20 UNF threads (such as the 330701 or 330702), the 330703 base model utilizes an M14 x 1.5 metric thread and does not feature stainless steel armor, facilitating installation through standard metric conduits. This probe integrates with a 3300 XL 11 mm Proximitor sensor and a 330730 extension cable to form a complete 5.0 m or 9.0 m transducer system, translating the physical gap between the probe tip and target into a proportional electrical voltage output.

Features

• M14 x 1.5 metric thread design without stainless steel armor.
• 0 mm unthreaded body length with 60 mm overall threaded case length.
• 1.0 meter (3.3 feet) standard coaxial cable length.
• Miniature coaxial ClickLoc connector for direct connection to extension cables.
• -CN China hazardous area approval suffix, certifying the probe for NEPSI and CCC requirements.
• Viton O-ring integrated sealing material to prevent internal pressure leakage.

Applications

Typical heavy-industry scenarios where this 11 mm system is used include:

• Turbine shaft vibration and axial position monitoring.
• Rotor position and thrust measurement in heavy rotating machinery.
• Industrial compressor and pump protection systems.
• Hydroelectric and steam turbine generator shaft displacement monitoring.

Installation Guidelines

Ensure correct installation of the 3300 XL 11 mm probe by adhering to the following engineering guidelines:

• Thread Engagement: For M14 x 1.5 metric threads, the maximum length of thread engagement should not exceed 21 mm to prevent binding or physical case distortion.
• Grounding and Shielding: The outer shield of the coaxial cable must remain isolated from the machine ground. House the connections in insulated sleeves or a dedicated junction box.
• Connector Protection: For environments exposed to moisture or oil, seal the ClickLoc connection using self-amalgamating tape or silicone-free connector protectors. Do not use standard silicone tape in contact with turbine oil.
• Probe Gap Setting: Calibrate and set the initial probe gap to the recommended standard setting of 2.5 mm (100 mils) using a digital voltmeter measuring the DC voltage of the Proximitor output.
• Bending Radius: Maintain the minimum bending radius of the standard coaxial cable (typically 25.4 mm or 1.0 inch) to avoid internal physical damage and signal attenuation.

Compliance and Certifications

This product configuration is certified to comply with standard safety guidelines, containing local certifications designated by the -CN option suffix:

• NEPSI: Explosion-proof certification for hazardous environments in China.
• CCC: China Compulsory Certification.
• CE / EMC: European Community Directive 2014/30/EU, meeting EN 61000-6-2 (Immunity) and EN 61000-6-4 (Emissions).
• RoHS: European Directive 2011/65/EU and China RoHS compliance.
