The PR6423/010-040 CON021 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 PR6423/010-040 CON021 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 PR6423/010-040 CON021 achieves DSL of ±0.025mm (±1 mil), making it suitable for applications requiring high measurement accuracy.
The PR6423/010-040 CON021 is designed for harsh industrial environments with an operating temperature range of -35°C to +180°C for the sensor including 1m cable, and -35°C to +150°C for the cable and connector. The PR6423/010-040 CON021 features IP66 protection per IEC 60529, providing resistance to dust and water ingress. The PR6423/010-040 CON021 is constructed with a PEEK sensor tip, stainless steel case, PTFE cable, and nickel-plated brass connector for chemical and corrosion resistance. The PR6423/010-040 CON021 weighs approximately 100g with 1m cable.
The PR6423/010-040 CON021 carries multiple hazardous area certifications including ATEX, IEC-Ex, and CSA, supporting both intrinsic safety (ia) and non-sparking (nA) approvals. The PR6423/010-040 CON021 has temperature classifications T6 (Ta ≤ 64°C), T4 (Ta ≤ 114°C), and T3 (Ta ≤ 160°C) depending on the converter and application. The PR6423/010-040 CON021 complies with CE directives including 2014/30/EU (EMC), 2014/34/EU (ATEX), and 2011/65/EU (RoHS). The PR6423-010-040-CON021 is available with M10x1 or 3/8-24 UNF case threads, armored cable options, and Lemo connector or open cable ends.
The PR6423/010-040 CON021 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 Generation: Steam, gas, and hydro turbines in power plants for core rotor monitoring.
- Oil & Gas / Petrochemical: High-speed centrifugal compressors, multi-stage pumps, and industrial fans.
- Mechanical Operations: Heavy gearboxes, blowers, and large electric motors.
- Temperature Range: Operates from -35°C to 200°C (-31°F to 392°F), letting it sit inside hot turbine housings.
- Sealing Protection: Features an IP66 / IP67 rated stainless steel sleeve structure that is highly resistant to aggressive turbine lubricating oils, high-pressure environments (up to 20 bar), and chemical vapor.
- Hazardous Area Certifications: The combined system is intrinsically safe, carrying global explosion-proof ratings such as ATEX, IECEx, and CSA for Zone 0, 1, and 2 environments.
- Signal Conversion & Sensitivity: The CON021 Converter powers the probe's driver circuit. It handles a linear measurement range of 2 mm (80 mils) with a nominal scale factor of 8 V/mm (203.2 mV/mil).
- Initial Setup (Gap Voltage): During installation, operators verify a 0.5 mm initial air gap. This typically yields a baseline bias/offset voltage around -10 VDC, which is monitored by technicians to ensure the probe remains centered within its linear range.
- System Integration: The negative raw voltage signal (-4 to -20 VDC or -2 to -18 VDC) feeds directly into dedicated machinery health protection systems like the Emerson AMS 6500 or legacy MMS 6000 / MMS 3000 systems.
