Product Overview
The Bently Nevada 330171-20-40-05-02-05 3300 5 mm Proximity Probe is a precision eddy current sensor designed for continuous monitoring of shaft vibration, displacement, and position changes in critical rotating machinery.
This proximity probe is widely used in industrial condition monitoring systems where accurate and reliable measurement of rotating equipment performance is required. It provides non-contact measurement between the probe tip and the rotating shaft, allowing stable operation in high-speed machinery environments.
By using eddy current sensing technology, the probe can detect very small changes in shaft movement and convert them into electrical signals for monitoring and protection systems. These signals help engineers evaluate machine health, identify abnormal operating conditions, and perform predictive maintenance.
The Bently Nevada 330171-20-40-05-02-05 is commonly installed on steam turbines, gas turbines, compressors, pumps, generators, and other rotating equipment where vibration monitoring and machinery protection are essential.

Function and Working Principle
The Bently Nevada 330171-20-40-05-02-05 proximity probe operates based on eddy current measurement technology.
The probe generates an electromagnetic field at the sensing tip. When the distance between the probe and the rotating shaft changes, the electromagnetic field is affected. These changes are converted into electrical signals that represent shaft movement and vibration levels.
The monitoring system analyzes these signals to determine the operating condition of the equipment and provide early warnings of possible mechanical problems.
Non-Contact Measurement Principle
Unlike traditional contact sensors, the proximity probe does not physically touch the rotating shaft.
This provides several advantages:
- Reduced mechanical wear
- Improved measurement stability
- Suitable for high-speed rotating equipment
- Long operational service life
- Reliable performance in harsh industrial environments
Shaft Vibration Detection
The probe continuously monitors shaft movement and helps detect abnormal machine behavior.
Typical monitoring functions include:
- Rotor vibration measurement
- Shaft displacement detection
- Mechanical imbalance identification
- Misalignment monitoring
- Equipment operating condition analysis
Position Monitoring Capability
In addition to vibration measurement, the probe can monitor shaft position changes, making it suitable for machinery protection and operational analysis.
