Product Introduction
The Bently Nevada 330903-00-03-10-02-CN 3300 NSv Proximity Probe is a specialized non-contact sensor designed for precise shaft vibration and position measurements in rotating machinery. Part of the 3300 NSv (Narrow Signal Velocity) series, this probe is particularly optimized for small machines such as gearboxes, pumps, and compressors where space constraints exist and high sensitivity is required.
It is engineered to work in combination with extension cables and Proximitor® sensors to deliver reliable monitoring of shaft dynamic behavior. The design ensures compatibility with API 670 requirements and provides consistent measurements even in challenging environments with high temperatures, electrical noise, or mechanical vibrations.
