Product Overview
Continuous condition monitoring plays a vital role in maximizing the reliability and operational efficiency of rotating machinery. The Bently Nevada 330704-005-040-10-02-00 3300 XL 11 mm Proximity Probe is a precision non-contact displacement sensor developed to measure shaft vibration, shaft position, rotor displacement, and dynamic movement in industrial rotating equipment.
As part of the 3300 XL 11 mm Proximity Transducer System, this proximity probe utilizes advanced eddy current sensing technology to accurately detect the distance between the probe tip and a conductive shaft surface. Its non-contact design minimizes mechanical wear while providing stable, repeatable measurements suitable for continuous industrial operation.
The 330704-005-040-10-02-00 incorporates a 40 mm probe case length, 11 mm sensing tip, M14 × 1.5 threaded mounting, armored construction, and a 1-meter total cable length, making it an excellent choice for vibration monitoring systems installed on turbines, compressors, generators, pumps, electric motors, and other critical rotating machinery.

Working Principle
The 330704-005-040-10-02-00 operates using eddy current sensing technology.
The sensing tip generates a high-frequency electromagnetic field. When positioned near a conductive rotating shaft, eddy currents are induced on the shaft surface. As the shaft moves during operation, the distance between the probe and the shaft changes, causing proportional variations in the electromagnetic field.
These variations are converted into electrical signals and processed by a compatible Proximitor Sensor, enabling accurate monitoring of:
- Shaft vibration
- Shaft displacement
- Rotor eccentricity
- Axial position
- Dynamic shaft movement
Because there is no physical contact between the probe and the shaft, measurement accuracy remains stable while mechanical wear is eliminated.
