This transducer provides valuable data, helping to optimize performance and prevent mechanical failures.

How It Works

The EPRO PR6423/268-110 operates in conjunction with a signal converter, forming a complete oscillator circuit. As a metallic object approaches the transducer, the amplitude of oscillation decreases. This damping effect is directly proportional to the distance between the transducer face and the object. Furthermore, the EPRO PR6423/268-110 system comes pre-calibrated, so users only need to adjust the gap between the transducer and the object to get accurate results. As a result, no on-site calibration is necessary.
