Technical Specifications

Function and Working Principle

The Bently Nevada 330171-00-20-10-02-05 operates based on eddy current sensing technology, allowing accurate measurement of shaft movement without direct contact.

During operation, the probe generates an electromagnetic field at the sensing tip. When the distance between the probe and the rotating shaft changes, the electromagnetic field changes accordingly. These changes are converted into electrical signals that represent shaft displacement and vibration conditions.

The main functions include:

• Measuring shaft vibration displacement
• Monitoring shaft radial movement
• Detecting abnormal mechanical conditions
• Providing continuous machinery operating data
• Supporting predictive maintenance activities

The non-contact measurement principle eliminates physical wear between the sensor and rotating components, allowing long-term stable operation in demanding industrial environments.
