Product Introduction
The Bently Nevada 330703-020-110-10-01-05 3300 XL 11 mm Proximity Probe is a high-precision, non-contact vibration and displacement sensor designed specifically for monitoring rotating machinery such as turbines, compressors, motors, and pumps. It belongs to the 3300 XL series, one of the most widely adopted proximity transducer systems in the world for machinery protection and condition monitoring.
This probe functions based on eddy-current sensing technology, detecting the distance between the probe tip and a conductive surface. The electrical signal generated corresponds precisely to the shaft displacement or vibration amplitude. The 330703-020-110-10-01-05 model ensures exceptional linearity, stability, and accuracy, even under challenging operational environments such as high temperature, oil exposure, and mechanical stress.
It works seamlessly with Bently Nevada 3300 XL Proximitor Sensors and compatible extension cables, forming a complete transducer system that adheres to API 670 standards. This makes it a critical element in the preventive maintenance and protection systems of industrial rotating machinery.
The rugged stainless steel design, superior electromagnetic interference protection, and long-term calibration stability make this probe suitable for continuous industrial service where equipment reliability is paramount.
