Features:
- Measures shaft vibration, position, and eccentricity without contacting the rotor.
- Designed for steam, gas, and hydro turbines, compressors, and fans.
- Rated Exe ib IIC T6/T4 for explosive area installations.
The PR6423/10R-131 CON031 is a non-contact eddy current displacement transducer designed for extremely critical turbomachinery applications. It measures shaft position and movement without contacting the rotor surface, providing accurate vibration and position data. The PR6423/10R-131 CON031 is ideal for sleeve bearing machines where the shaft is separated from the bearing material by a thin film of oil. The PR6423/10R-131 CON031 is commonly used to measure vibration of machine shafts, eccentricity, thrust (axial displacement), differential expansion, valve position, and air gaps.
The PR6423/10R-131 CON031 meets international standards including DIN 45670, ISO 10817-1, and API 670, ensuring it meets stringent requirements for critical machinery monitoring. The PR6423/10R-131 CON031 features a rugged construction designed for extremely critical turbomachinery applications. The PR6423/10R-131 CON031 is rated for explosive areas with Exe ib IIC T6/T4 certification. The PR6423/10R-131 CON031 weighs approximately 0.5 kg (1.1 lbs) and is available in various configurations.
The PR6423/10R-131 CON031 requires a converter such as CON 011/91, CON 021/91, or CON 041/91, and a cable for a complete transducer system. This allows the PR6423/10R-131 CON031 to be easily integrated into existing monitoring systems. The PR6423/10R-131 CON031 provides non-contact measurement of static and dynamic shaft displacement including axial and radial shaft displacement (position), shaft eccentricity, and shaft vibration (motion). The PR6423/10R-131 CON031 is widely used in power generation, oil and gas, and petrochemical industries.
The PR6423/10R-131 CON031 EMERSON 8mm Eddy Current Displacement Transducer may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Target Machinery: Heavily deployed on steam turbines, gas turbines, turbo-compressors, boiler feed pumps, industrial fans, and hydro-generators.
- Shaft Vibration (Radial): Measures micro-level dynamic shaft displacement within journal bearings to detect unbalance, misalignment, or oil whirl.
- Shaft Position (Axial/Thrust): Monitors axial movement of the shaft relative to the casing to prevent catastrophic thrust bearing failures.
- Eccentricity & Speed: Tracks shaft bowing during slow-roll/turning-gear operations, as well as providing precise phase triggers (Keyphasor) for speed calculation.
- No Microcontroller Firmware: The CON031 driver uses hardwired, high-frequency analog circuitry to generate an eddy current field and demodulate the return signal. It does not possess a flash memory chip or digital firmware that can be updated via software.
- Hardware Revisions & Replacements: Updates to this system are managed through physical hardware engineering revisions. Legacy installations utilizing older epro components (e.g., CON011 or older PR6423 versions) are updated by directly swapping them with modern, backward-compatible Emerson equivalents like the MMS 3000/6000 series or the AMS 6500 ATG system.
- Environmental Upgrades: Modern replacements often inherit structural updates, such as improved hermetic sealing, chemical-resistant FEP cable jackets, or advanced internal surge protection layers.
- Target Material Calibration: The measurement chain is factory-calibrated to a specific rotor steel chemistry (typically standard European 42CrMo4 / AISI 4140 steel). If your machine shaft uses a different alloy (e.g., stainless steel or specialized carbon steel), the conversion slope changes, requiring a custom factory-calibrated variant or post-signal gain adjustments at the receiver module.
- Mechanical Gap Optimization (Zeroing): Hardware configuration is performed during physical installation. The probe is threaded into its reverse-mount bracket until it reaches the linear voltage centerpoint (typically around -10.0 V DC relative to the target surface, corresponding to a roughly 1.0 mm physical gap for standard 8V/mm sensitivity).
- Driver-Cable Loop Matching: The system operates strictly as a tuned RF circuit. The CON031 driver is specifically tuned for an 8.0-meter internal cable length (denoted by the code 3 in the model name). Modifying or cutting the integrated cable will destroy the impedance balance, skewing the output voltage accuracy.
