Technical Specifications

Function and Working Principle

The Bently Nevada 330192-00-70-05-CN operates using advanced eddy current sensing technology to measure the distance between the probe tip and a conductive rotating shaft.

During operation, the probe generates a high-frequency electromagnetic field. When the rotating shaft moves closer or farther from the sensing tip, the electromagnetic field changes. These variations are converted into electrical signals that represent shaft movement and displacement.

The working process includes:

• Generating an electromagnetic sensing field
• Detecting changes in shaft position
• Measuring vibration and displacement movement
• Converting mechanical movement into electrical signals
• Sending monitoring information to the protection system

Main measurement functions include:

• Radial shaft vibration monitoring
• Axial displacement measurement
• Rotor position monitoring
• Mechanical condition analysis
• Rotating equipment protection

Because the probe operates without physical contact, it provides long service life and stable measurement performance in continuous industrial operation.
