Product Overview
Reliable machinery protection depends on accurate, continuous monitoring of shaft vibration and position. The Bently Nevada 330705-02-18-10-02-05 3300 XL 11 mm Reverse Mounting Probe is a high-precision non-contact displacement sensor engineered for industrial condition monitoring applications where a reverse mounting configuration is required.
As part of the 3300 XL 11 mm Proximity Transducer System, this probe uses advanced eddy current sensing technology to continuously measure shaft vibration, shaft position, eccentricity, and rotor displacement. Its reverse mounting structure allows installation from the opposite side of the mounting bracket, providing greater flexibility for equipment with limited installation space or special mechanical layouts.
The 330705-02-18-10-02-05 combines an 11 mm sensing tip, reverse mounting design, 1-meter total cable length, rugged industrial construction, and lightweight 0.17 kg design, making it an ideal solution for turbines, compressors, generators, motors, pumps, and other mission-critical rotating machinery.

The reverse mounting design offers additional flexibility for machines with restricted mounting access.
Working Principle
The 330705-02-18-10-02-05 operates using proven eddy current sensing technology.
The sensing tip generates a controlled electromagnetic field. When positioned close to a conductive rotating shaft, eddy currents are induced on the shaft surface. As the shaft moves during operation, changes in the probe-to-target distance alter the electromagnetic field strength.
These changes are converted into electrical signals that are processed by a compatible Proximitor Sensor, providing accurate measurements of:
- Shaft vibration
- Shaft position
- Rotor displacement
- Shaft eccentricity
- Dynamic machine movement
Since there is no physical contact between the probe and the rotating shaft, the sensor provides excellent durability and measurement stability.
