Function and Working Principle
The Bently Nevada 330171-24-32-20-02-05 proximity probe operates using eddy current sensing technology to measure the distance between the probe tip and a conductive rotating shaft.
The sensor generates an electromagnetic field at the probe tip. When the shaft position changes, the electromagnetic field changes accordingly. These variations are converted into electrical signals that represent shaft displacement and vibration movement.
The collected signals are transmitted to monitoring equipment, allowing engineers to analyze machine operating conditions and identify potential mechanical problems.
