Product Overview
The Bently Nevada 330703-000-060-50-12-00 3300 XL 11 mm Proximity Probe is a high-precision non-contact displacement sensor designed for continuous monitoring and protection of critical rotating machinery in industrial applications.
As part of the 3300 XL 11 mm Proximity Probe series, this model provides accurate measurement of shaft vibration, radial displacement, and axial position. The probe uses proven eddy current sensing technology to detect changes in the distance between the probe tip and the rotating shaft surface without physical contact.
The 330703-000-060-50-12-00 features a 60 mm case length and a 5-meter total cable length, making it suitable for installations where the sensor needs to be positioned away from the monitoring cabinet or signal conditioning equipment. With a weight of 0.25 kg, this configuration provides extended installation flexibility while maintaining reliable measurement performance.
This proximity probe is widely used in machinery protection systems where accurate vibration monitoring and early detection of mechanical problems are required.
Typical applications include:
- Steam turbine monitoring
- Gas turbine protection
- Compressor vibration monitoring
- Generator condition analysis
- Pump and motor monitoring
- Rotating equipment diagnostics
- Predictive maintenance systems

Working Principle
The Bently Nevada 330703-000-060-50-12-00 Proximity Probe operates using eddy current displacement measurement technology.
The probe generates a high-frequency electromagnetic field at the sensing tip. When the rotating shaft moves closer or farther away from the probe, the electromagnetic field changes. These changes are converted into electrical signals that represent shaft displacement and vibration conditions.
The measurement process includes:
- The probe creates an electromagnetic sensing field.
- The rotating shaft changes the probe gap distance.
- The sensor detects changes in the electromagnetic field.
- The signal is converted into displacement data.
- The monitoring system evaluates machine operating conditions.
Because the probe operates without direct contact with the rotating shaft, it eliminates mechanical wear and provides reliable long-term operation in high-speed machinery environments.
