The Epro PR6424/000-000+CON021/913-040 is a high-precision eddy current proximity sensor used primarily for non-contact vibration and displacement measurements in rotating machinery. Engineered with a 16mm probe diameter, this sensor is part of Epro’s advanced PR6424 series, known for robust design, signal stability, and long-term reliability even in harsh industrial environments.

Combined with the CON021/913-040 converter, the sensor forms a complete transducer system that translates proximity changes into linear voltage signals. This makes it ideal for integration into condition monitoring and protection systems used in turbines, compressors, pumps, and other critical rotating assets. The PR6424 is fully compatible with VM600, MMS6000, and Bentley Nevada monitoring systems, making it a highly versatile and widely adopted solution across industries.
