Product Overview
Modern industrial facilities rely on continuous condition monitoring to maximize equipment reliability and minimize unplanned downtime. The Bently Nevada 330704-000-XXX-10-01-CN 3300 XL 11 mm Proximity Probe is a high-performance non-contact displacement sensor engineered for precise measurement of shaft vibration, shaft position, and rotor displacement in critical rotating machinery.
As a member of the 3300 XL 11 mm Proximity Transducer System, this proximity probe utilizes proven eddy current sensing technology to detect the distance between the probe tip and a conductive target surface. Its non-contact operating principle eliminates mechanical wear while providing accurate and repeatable measurements in demanding industrial environments.
The 330704-000-XXX-10-01-CN represents a configurable model within the 3300 XL 11 mm product family, where the “XXX” portion identifies different probe body lengths or configuration options. With a 1-meter total cable length, armored construction, and industrial-grade design, this probe is widely used for continuous monitoring of turbines, compressors, generators, motors, pumps, and other rotating equipment.

Working Principle
The 330704-000-XXX-10-01-CN operates using advanced eddy current sensing technology.
The probe continuously generates a high-frequency electromagnetic field at its sensing tip. When installed near a conductive rotating shaft, eddy currents are induced on the shaft surface. Variations in the shaft-to-probe distance change the electromagnetic field strength, allowing the probe to generate proportional electrical signals.
These signals are processed by the matching Proximitor Sensor, providing accurate measurements for:
- Shaft vibration
- Radial displacement
- Axial position
- Rotor movement
- Mechanical condition monitoring
Because the measurement is completely non-contact, the probe offers excellent reliability and extended service life.
