Bently Nevada 330105-02-12-15-02-CN 3300 XL 8 mm Reverse Mount Probe

Description

The 330105-02-12-15-02-CN 3300 XL 8 mm reverse mount proximity probe is configured with 0.2 in unthreaded length, 1.2 in case length, 1.5 m total length, and a standard miniature ClickLoc coaxial connector. This specific configuration includes the -CN suffix, which signifies compliance with the China hazardous area approval package, including NEPSI and CCC certifications.

Designed for installation where the probe must be mounted through the machine casing from the inside, this 3300 XL 8 mm proximity probe is a fundamental component of the 3300 XL transducer system. It delivers precise, non-contact displacement measurement for critical rotating machinery, including turbine-generators, compressors, and pumps. The system integrates with 3300 XL Proximitor sensors and extension cables to monitor shaft vibration and axial position, ensuring operational data accuracy within industrial protection environments.

Installation Guidelines

Ensure the probe is installed in a secure, vibration-resistant mount. When using the reverse mount configuration, verify that the internal casing mount is correctly tightened to prevent mechanical drift. Maintain the specified air gap between the probe tip and the target shaft surface to ensure linear operation. Proper shielding of the coaxial extension cable is required to mitigate electromagnetic interference in industrial environments. Ensure that the -CN certified installation complies with all local hazardous area standards for China.

Compliance and Certifications

• CE marked for applicable directives
• China hazardous area approval package (NEPSI + CCC) via -CN suffix
• Compatible with CSA, ATEX, and IECEx systems when used in non-CN applications (verification of specific system compliance required)
