Product Introduction
The Bently Nevada 330101-00-14-20-02-CN is an 8 mm proximity probe from the 3300 XL series, one of the most reliable and widely deployed sensor systems in the world for non-contact vibration and position measurement of rotating machinery. Built for durability and precision, this probe is part of a three-component system comprising a proximity probe, extension cable, and Proximitor sensor, which together offer high-resolution measurements critical for condition monitoring and protection.
This particular model features a 14-foot probe cable and 20-foot extension cable, designed to deliver accurate displacement readings and ensure stable performance in rugged industrial environments. As with all Bently Nevada XL series components, the 330101-00-14-20-02-CN offers outstanding EMI resistance, robust mechanical integrity, and excellent long-term stability, making it a gold standard in machinery protection systems.
