Bently Nevada 330101-33-53-10-02-CN 3300 XL 8 mm Proximity Probe Metric

Product Overview

The 330101-33-53-10-02-CN 3300 XL 8 mm proximity probe from Bently Nevada is designed for continuous shaft vibration and position monitoring in critical rotating machinery such as turbines, compressors, pumps, and generators. It is widely used in power generation, oil and gas processing, petrochemical plants, and heavy industrial systems where reliable condition monitoring is required to reduce unplanned downtime and improve asset protection.

This metric-configured probe is part of the 3300 XL proximity measurement system and delivers stable signal performance under harsh industrial conditions including vibration, contamination, and thermal stress. The 3.3 in unthreaded length and 5.3 in overall case length support flexible installation in metric mounting environments. The 1.0 m total cable length ensures practical routing within compact machinery assemblies. The miniature coaxial ClickLoc connector provides stable electrical connection under continuous vibration conditions. The CN approval option supports hazardous area deployment with country-specific approvals including NEPSI, CCC, and applicable ATEX or IECEx certification requirements.
