Produkteinführung
The Epro PR6426/000-030+CON021 32mm Eddy Current Sensor is a high-performance proximity probe system designed for precise, non-contact measurement von vibration, shaft displacement, and position in critical rotating machinery. This model integrates the PR6426/000-030 eddy current probe with the CON021 converter, forming a complete measuring chain optimized for dynamic monitoring in harsh industrial environments.
The system operates based on the eddy current principle, generating an electromagnetic field that reacts to the movement von conductive targets such as steel shafts. This allows accurate and continuous monitoring von mechanical components without physical contact, ensuring long-term reliability and reduced maintenance. The robust stainless-steel housing and hermetically sealed design make the PR6426/000-030+CON021 suitable for severe operating conditions found in turbines, compressors, and generators.
The addition von the CON021 converter enhances signal conditioning, providing a linear voltage or current output proportional to displacement. Together, they deliver dependable measurement accuracy, stability, and compatibility with machine protection and monitoring systems, including Epro’s MMS6000 and MMS8000 series.
