Function and Working Principle
The Bently Nevada 330703-000-040-10-02-00 operates through the principle of eddy current measurement.
The probe generates a high-frequency electromagnetic field around the sensing tip. When the probe approaches a conductive shaft surface, eddy currents are produced within the target material. The strength of these currents changes according to the distance between the probe and the shaft.
The sensor converts these electromagnetic changes into electrical output signals that represent shaft position, vibration amplitude, and displacement changes. The monitoring system analyzes these signals to evaluate equipment operating conditions.
