Bently Nevada 330101-00-18-10-02-CN 3300 XL 8 mm Proximity Probe

Description

The 330101-00-18-10-02-CN is a Bently Nevada 3300 XL 8 mm proximity probe designed for non-contact displacement measurement in critical machinery monitoring chains. This configuration features a 3/8-24 UNF thread, a 0.0 in unthreaded length (Option 00), a 1.8 in case length (Option 18), and a 1.0 m total system length (Option 10). It is equipped with a standard miniature coaxial ClickLoc connector (Option 02) and includes the -CN suffix, which denotes the China hazardous area approval package (NEPSI and CCC certification) for regulatory compliance in Chinese industrial environments.

This 8 mm probe is a fundamental component of the 3300 XL transducer system, which reliably measures shaft vibration, axial position, and rotor speed in steam turbines, compressors, and pumps. The probe pairs with a 3300 XL extension cable and a 3300 XL Proximitor sensor, providing a linear, high-precision voltage output proportional to the gap between the probe tip and the observed target material.

Features

• 3300 XL 8 mm transducer platform with 3/8-24 UNF thread (unarmored)
• Option 00: 0.0 in unthreaded length for maximum installation flexibility
• Option 18: 1.8 in overall case length
• Option 10: 1.0 m total system length (probe plus cable)
• Option 02: Standard miniature coaxial ClickLoc connector
• Suffix -CN: Specialized certification package for China (NEPSI/CCC)
• Compatible with 3300 XL Proximitor sensors and standard Bently Nevada extension cables

Applications

• Turbine and compressor shaft vibration monitoring
• Axial position (thrust) measurement
• Speed and phase reference sensing for critical rotating machinery
• Industrial installations requiring NEPSI and CCC hazardous area compliance

Installation Guidelines

Ensure the probe is mounted using the recommended Bently Nevada mounting brackets (e.g., 27474-AA or 137492-AA). When installing in hazardous areas, verify that the system is connected to approved zener barriers or galvanic isolators per local regulatory drawings. Ensure the probe tip gap is set according to the machinery monitoring requirements; typically, a median gap voltage of -9V to -11V is used for standard proximity applications.
