EPRO PR6423/002-041 Eddy Current Displacement Sensor
Product Overview
The EPRO PR6423/002-041 is an eddy current displacement sensor from the Emerson EPRO PR6423 series. It is designed for non-contact measurement of shaft vibration, displacement and position in critical rotating machinery such as steam turbines, gas turbines, compressors, pumps and fans.
The PR6423 series uses eddy current technology to measure the distance between the probe tip and a conductive metal surface without physical contact. The “/002-041” suffix defines a specific configuration within the PR6423 family, typically related to cable length, connector type or calibration details. Exact configuration should be confirmed against the product label before ordering.
Key Features
- Non-contact eddy current measurement with no mechanical wear
- High sensitivity of 8 V/mm for precise displacement detection
- ±1.0 mm static measuring range with linear error ≤ ±1%
- Robust stainless steel construction for harsh industrial environments
- Wide operating temperature range from -35°C to +180°C, up to +200°C short term
- Strong anti-interference capability with electromagnetic shielding design
- Compatible with CON011, CON021, CON031 converters for complete measurement chain
- Compliant with API 670, DIN 45670, ISO 10817-1 standards
