Product Introduction
The Bently Nevada 330709-050-120-10-02-00 3300 XL 11 mm Proximity Probe is a precision-engineered, non-contact vibration and displacement sensor designed for critical rotating machinery monitoring. As part of the 3300 XL Series, it delivers high reliability, accuracy, and stability in demanding industrial environments, including turbines, compressors, pumps, and motors.
The probe operates using the eddy current principle, generating an electromagnetic field near a conductive target such as a rotating shaft. Variations in this field are converted into a proportional voltage signal, representing shaft displacement or vibration amplitude. When paired with a 3300 XL Proximitor Sensor, it provides precise, real-time monitoring for machinery protection and predictive maintenance.
Constructed with stainless steel, the probe offers robust mechanical durability, temperature stability, and EMI/RFI resistance through its double-shielded coaxial cable. Designed to comply with API 670 standards, the probe ensures reliable operation in critical industrial applications worldwide.
