Bently Nevada 330104-00-22-10-02-CN 3300 XL 8 mm Proximity Probe

Description

Option 00 (0 mm unthreaded length) and Option 22 (220 mm overall case length) specify this metric, armored probe configuration — 330104-00-22-10-02-CN, a 3300 XL 8 mm proximity probe with an M10 x 1 threaded body. This configuration includes a 1.0 meter total cable length and a miniature ClickLoc coaxial connector. It features the -CN suffix, which integrates the China hazardous area approval package, certifying the unit with NEPSI and CCC approvals for explosive atmospheres.

Unlike unarmored alternatives in the 330103 series, the 330104 configuration incorporates flexible AISI 302 or 304 stainless steel armor with an FEP outer jacket. This provides mechanical defense against physical impact, abrasive debris, and harsh fluid exposure. The 220 mm case length is optimized for machinery installations with deep-set sensor housings, measuring shaft vibration and axial position on high-speed industrial rotating machinery.

Features

• M10 x 1 threaded body configuration with flexible stainless steel armor and FEP outer jacket.
• Zero unthreaded length (Option 00) paired with a 220 mm case length (Option 22).
• 1.0 meter (3.3 feet) total cable length (Option 10).
• Miniature coaxial ClickLoc connector (Option 02) without a connector protector.
• China hazardous area approval package (NEPSI and CCC) specified by the -CN suffix.
• Polyphenylene sulfide (PPS) probe tip and AISI 303/304 stainless steel body construction.
• Built-in Viton O-ring for robust differential pressure sealing.

Applications

• Shaft dynamic vibration and axial position monitoring on utility steam and gas turbines.
• Condition monitoring on industrial centrifugal compressors and turbochargers.
• Critical rotating machinery protection inside oil refineries, petrochemical plants, and power plants.
• Industrial installations requiring hazardous area certifications in mainland China.

Installation Guidelines

• Keep cable bends at a minimum radius of 25.4 mm during installation to prevent internal wiring wear.
• Ensure the probe thread is installed using a recommended torque of 22.6 N-m; do not exceed the maximum rating of 33.9 N-m.
• Ensure ClickLoc connectors are clean and dry before mating. Finger-tighten until the tactile click occurs to secure connection.
• Do not expose the probe assembly to temperatures below -34 degC to protect the Viton pressure seal from degradation.

Compliance and Certifications

• China Hazardous Area Certification: NEPSI Ex ia IIC T5...T1 Ga, CCC certified.
• Electromagnetic Compatibility: EN 61000-6-2 (Industrial Immunity), EN 61000-6-4 (Industrial Emissions).
• Environmental Compliance: EU RoHS Directive 2011/65/EU, China RoHS 15-year EFUP designation.
• Functional Safety: SIL 2 (HFT=0) and SIL 3 (HFT=1) compliant in dual-configuration systems.
