The ability to measure these critical parameters helps in the early detection of issues, reducing downtime and maintenance costs in industrial machinery.

How It Works

The EPRO PR6423/165-110 operates based on the principle of eddy current measurement. It generates an oscillator circuit that interacts with metallic objects. The proximity of a metallic object dampens the oscillation amplitude, providing accurate distance measurements. The distance between the sensor and the object directly affects the signal, which allows precise measurements of displacement and vibration.

Additionally, the EPRO PR6423/165-110 system includes a signal converter (CON) that works in conjunction with the sensor. The system comes fully calibrated, eliminating the need for on-site calibration. Users only need to adjust the gap between the sensor and the object to achieve the desired signal output.

Key Features

Contactless Measurement: Reduces wear and tear on the sensor, ensuring longer service life and lower maintenance.
High Sensitivity: Measures even small displacements with a sensitivity of 2 V/mm (50.8 mV/mil).
Robust Construction: Designed to withstand harsh industrial environments, providing reliable performance in critical applications.
Pre-Calibrated System: Arrives fully calibrated, simplifying installation and operation.
