How It Works

The EPRO PR6423/099-110 system forms an oscillator circuit with its signal converter. As a metallic object approaches the transducer, the amplitude of oscillation diminishes. This damping is directly related to the distance between the sensor and the object. The system allows for high-precision measurements, even in environments where physical contact is not possible.

Once the system is delivered, it comes fully calibrated, so no on-site adjustments are necessary. You only need to adjust the gap between the transducer and the target to achieve the specified signal output.

Conclusion

Thanks to its innovative design and advanced eddy current technology, the EPRO PR6423/099-110 transducer system excels in providing reliable, high-accuracy measurements in challenging environments. Its robustness, ease of integration, and precision make it the top choice for industries that require dependable measurement solutions for turbomachines and other critical systems.
