Product Introduction
The Epro PR6425/010-100+CON021 is a 16mm Eddy Current Sensor designed for precise, reliable, and non-contact measurement of displacement, vibration, and position in industrial machinery. This sensor integrates the PR6425/010-100 measurement head with the CON021 signal conditioning unit, providing a complete system for high-resolution monitoring and control applications.
Operating on the eddy current principle, the sensor head detects minute variations in distance to conductive targets, converting them into stable electrical signals through the CON021 unit. This allows for real-time feedback, accurate monitoring, and predictive maintenance. The 16mm diameter head provides a practical balance between compactness and measurement performance, enabling installation in both tight and standard industrial environments.
This sensor is engineered for environments with vibration, temperature variations, and electromagnetic interference, ensuring stable operation in power generation, turbines, compressors, industrial automation, and heavy machinery applications. Its robust construction and high accuracy make it suitable for both critical process monitoring and control systems.
