The PR6423/011-000 is an 8mm eddy current sensor providing high-precision measurement of shaft dynamic displacement, position, eccentricity, and speed. With a linear measurement range of 2mm (80 mils) and an initial air gap of 0.5mm (20 mils), the PR6423/011-000 delivers accurate data for critical turbomachinery monitoring. The Incremental Scale Factor of 8 V/mm (203.2 mV/mil) ±5% over 0°C to 45°C ensures reliable signal output. The PR6423/011-000 achieves DSL of ±0.025mm (±1 mil), making it suitable for applications requiring high measurement accuracy.
The PR6423/011-000 features an armored cable for enhanced mechanical protection against physical damage, making it suitable for harsh industrial environments. The sensor operates from -35°C to +180°C for the sensor including 1m cable, and -35°C to +150°C for the cable and connector. The PR6423/011-000 features IP66 protection per IEC 60529, providing resistance to dust and water ingress. The PR6423/011-000 is constructed with a PEEK sensor tip, stainless steel case, PTFE cable, and nickel-plated brass connector.
The PR6423/011-000 carries multiple hazardous area certifications including ATEX, IEC-Ex, and CSA, supporting both intrinsic safety (ia) and non-sparking (nA) approvals. The PR6423/011-000 has temperature classifications T6 (Ta ≤ 64°C), T4 (Ta ≤ 114°C), and T3 (Ta ≤ 160°C) depending on the converter and application. The PR6423/011-000 complies with CE directives including 2014/30/EU (EMC), 2014/34/EU (ATEX), and 2011/65/EU (RoHS). The PR6423/011-000 features an M10x1 case thread and is available with Lemo connector or open cable ends.
The PR6423/011-000 Emerson 8mm Eddy Current Sensor may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Power Plants: Installed on high-capacity steam turbines, utility gas turbines, hydro-turbines, and generator bearings.
- Hydrocarbon Infrastructure: Protects high-speed centrifugal compressors, turbo-expanders, and multi-stage process pumps in oil refineries and gas processing facilities.
- Heavy Process Industries: Tracks the shaft health of large industrial blowers, boiler feed pumps, air separators, and massive gearboxes in steel or pulp mills.
- Aviation & Marine Propulsion: Monitors critical high-RPM test beds, turbochargers, and primary propulsion shaft dynamics.
- Extreme Temperatures: The sensor head, integrated cable, and standard connector are engineered to operate reliably across a vast temperature range from -35 °C to +150 °C (-31 °F to +302 °F).
- Aggressive Fluid Resistance: The probe tip material is structurally immune to chemical corruption from synthetic oils, aggressive hydraulic fluids, industrial lubricants, and ambient moisture.
- Ingress & Hermetic Protection: The sensor casing and tip meet IP68 ingress standards, meaning it can withstand high-pressure spray-downs and continuous immersion under oil or water without seal degradation.
- Hazardous Area Certification: The PR6423 series offers explosion-proof compliance (including ATEX, IECEx, and regional certifications) for deployment in Zone 0, Zone 1, and Zone 2 explosive gas and vapor environments.
- Primary Metrics Measured: Captures vital mechanical variables including radial shaft vibration (dynamic movement within the bearing clearance), axial shaft position / thrust (preventing rotor-to-stator collision), and rotational speed / phase reference (Keyphasor applications).
- Sensor Loop Topology: The sensor is paired with an extension cable and connects to an Emerson CON011 / CON021 / CON041 signal converter (driver). This converter transforms the raw high-frequency field variation into a standardized analog voltage signal (typically 8 V/mm or 200 mV/mil).
- Monitoring System Integration: The conditioned analog signal feeds directly into specialized vibration monitoring racks, such as the Emerson AMS 6500 Machinery Health Monitor or the CSI 6500 Protection System.
- Safety Interlocks & Control Room: The AMS 6500 rack processes the metrics to drive real-time automated relay trips (for machinery emergency shutdown) and outputs data via Modbus TCP/IP or Ethernet to the plant's central Distributed Control System (DCS), PLC, or AMS Machine Works predictive maintenance software.
