Product Introduction
The Bently Nevada 330709-00-050-10-02-00 3300 XL 11 mm Proximity Probe is a precision-engineered, non-contact vibration and displacement measurement sensor developed for the most demanding rotating machinery applications. As part of the Bently Nevada 3300 XL Series, it is designed to provide reliable and highly accurate measurements in harsh industrial environments such as turbines, compressors, pumps, and motors.
Operating on the eddy current principle, the probe detects changes in the electromagnetic field when placed near a conductive target, typically the surface of a rotating shaft. This signal is then converted into a voltage output proportional to shaft vibration or displacement. When used together with a 3300 XL Proximitor Sensor and compatible extension cable, the system ensures precise, real-time monitoring of machinery health conditions.
The 330709-00-050-10-02-00 model combines robust mechanical construction, excellent temperature stability, and superior EMI/RFI immunity, allowing it to deliver consistent performance over extended operational periods. Designed to meet API 670 standards, it provides industry-standard performance for predictive maintenance and machinery protection systems.
