Operating Principle

The EPRO PR6423/231-110 uses an eddy current transducer paired with a signal converter to form an oscillator circuit. The amplitude of oscillation is affected by the proximity of a metallic object in front of the transducer. This damping effect is proportional to the distance between the transducer face and the object being measured.

The system is delivered fully adjusted, so no onsite calibration is required. The only adjustment needed is to set the gap between the transducer and the object to achieve the desired signal at the converter’s output.
