Product Overview
Accurate shaft vibration and position monitoring are essential for maintaining the reliability and safety of critical rotating machinery. The Bently Nevada 330705-02-18-10-02-00 3300 XL 11 mm Reverse Mounting Probe is a precision non-contact displacement sensor designed specifically for applications where conventional front-mounted probes cannot be installed.
As a member of the 3300 XL 11 mm Proximity Transducer System, this reverse mounting probe utilizes advanced eddy current sensing technology to continuously monitor shaft vibration, shaft position, and rotor displacement without making physical contact with the rotating component. The reverse mounting design provides greater installation flexibility while maintaining the high accuracy and stability expected from the 3300 XL series.
The 330705-02-18-10-02-00 features a reverse mounting configuration, 11 mm sensing tip, 1-meter total cable length, rugged industrial construction, and lightweight 0.17 kg design, making it suitable for turbines, compressors, generators, pumps, motors, and other rotating equipment where installation space or mechanical layout requires rear-mounted sensing.

Product Features
The 330705-02-18-10-02-00 is designed to provide reliable condition monitoring while simplifying installation in applications with restricted mounting access.
Key features include:
- Reverse mounting design for specialized installation requirements
- High-precision non-contact displacement measurement
- Stable performance during continuous industrial operation
- Excellent resistance to vibration and electromagnetic interference
- Rugged industrial construction for harsh environments
- Long operational life with minimal maintenance
- Compatible with the complete Bently Nevada 3300 XL monitoring platform
Its reverse mounting configuration makes it particularly suitable for machinery where front-mounted probes are impractical.
Working Principle
The 330705-02-18-10-02-00 operates using proven eddy current sensing technology.
The probe tip generates a high-frequency electromagnetic field directed toward a conductive rotating shaft. As the shaft rotates, eddy currents are induced on its surface. Variations in the shaft-to-probe distance alter the electromagnetic field, generating proportional electrical signals.
These signals are transmitted to a compatible Proximitor Sensor, which converts them into accurate measurements of:
- Shaft vibration
- Shaft displacement
- Rotor eccentricity
- Axial shaft position
- Dynamic shaft movement
Because the measurement process is completely non-contact, the probe delivers excellent long-term stability and minimizes mechanical wear.
