Product Introduction

The Bently Nevada 330704-000-040-10-02-05 3300 XL 11 mm Proximity Probe is a precision-engineered non-contact vibration and displacement sensor designed for advanced condition monitoring and machinery protection. It is part of the world-renowned 3300 XL series developed by Bently Nevada, a leader in machinery diagnostics and asset protection technologies.

This proximity probe operates based on eddy current sensing technology, detecting the distance between the probe tip and a conductive surface such as a rotating shaft. It delivers a voltage output that is directly proportional to the distance between the probe and the target, enabling precise measurement of shaft vibration, displacement, and position.

The 330704-000-040-10-02-05 model combines superior measurement accuracy, wide operating range, and rugged durability, making it suitable for critical rotating equipment such as turbines, compressors, motors, and pumps. Its stainless-steel construction, enhanced electromagnetic shielding, and stable calibration performance make it one of the most reliable sensors for industrial monitoring.

This probe is used in conjunction with Bently Nevada 3300 XL Proximitor Sensors and extension cables to form a complete transducer system compliant with API 670 standards. It ensures consistent and high-quality data collection for vibration analysis and equipment protection in demanding environments.
