Description
Overview
The EPRO PR6423/001‑011 is a high-precision, non-contact eddy current proximity sensor engineered for advanced shaft monitoring in turbomachinery. Featuring an 8 mm probe and robust stainless steel housing, this sensor delivers accurate measurement of vibration, radial and axial displacement, and eccentricity. Its design ensures reliability in harsh industrial environments and compatibility with API 670-compliant machine protection systems.
Applications
-
Radial and axial shaft displacement and vibration monitoring
-
Steam turbines, gas turbines, compressors, pumps, and industrial fans
-
Integration with API 670 machine protection systems
-
Compatible with CON011, CON021, CON031, CON041 converters and AMS 3000 series monitoring modules
Key Advantages
-
Extended Measurement: 8 mm sensor head allows ranges of 0–2 mm, extendable to ~3 mm depending on converter configuration
-
Non-Contact Design: Eliminates mechanical wear, providing long-term stability and low maintenance
-
High Accuracy: Static accuracy ≤ ±1.5%, wide dynamic frequency response up to 10 kHz
-
Rugged Construction: Stainless steel housing with armored cable suitable for extreme temperatures and pressures
-
Flexible Integration: Works seamlessly with multiple converters and monitoring modules
