Features:
- Wide frequency response from 0 to 20,000 Hz with <15 µs rise time enables high-speed monitoring of radial and axial shaft displacement, position, eccentricity, and speed on critical turbomachinery.
- Multiple hazardous area approvals including ATEX Ex ia IIC T4, IECEx, and CSA Class I Division 1/2 allow deployment in explosive environments worldwide with intrinsic safety or non-sparking configurations.
- Robust environmental specifications with operating temperature -30 to 100°C, 5g shock and vibration resistance.
The PR6423/004-120-CN CON021 delivers exceptional dynamic performance with a frequency range extending from DC to 20,000 Hz and a rise time of less than 15 microseconds. This wide bandwidth captures both static shaft position and high-frequency vibration components essential for diagnosing developing faults in high-speed rotating equipment. For steam and gas turbines operating at speeds exceeding 10,000 RPM, the converter’s rapid response ensures that critical events such as rubs, instabilities, and transient vibrations are detected and recorded before they escalate into catastrophic failures.
The PR6423/004-120-CN CON021 carries multiple hazardous area certifications that enable deployment in classified locations across North America, Europe, and international markets. Its intrinsic safety (ia) rating—ATEX II 2 G Ex ia IIC T4 Gb, IECEx Ex ia IIC T4 Gb, and CSA Class I Division 1—allows direct installation in Zone 0, 1, or Division 1 areas when used with appropriate safety barriers. For less demanding environments, non-sparking (nA) approvals cover Zone 2 and Division 2 applications.
Built to withstand the most demanding industrial conditions, the PR6423/004-120-CN CON021 operates reliably across a wide temperature range of -30 to 100°C, making it suitable for both Arctic outdoor installations and turbine casings where heat is a constant factor. Its ability to withstand 5g shock and vibration at 60 Hz ensures continued accuracy even on equipment with significant mechanical excitation. The IP20-rated housing, constructed from LMgSi 0.5 F22 aluminum alloy, provides protection against dust and incidental contact while maintaining lightweight characteristics at just 120 grams.
The PR6423/004-120-CN CON021 Emerson Epro Eddy Current Signal Converter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Key Power Equipment: Widely used in steam turbines, gas turbines, and water turbines.
- Heavy-duty Industrial Compressors: Used for monitoring the operating status of centrifugal and axial flow compressors.
- Environmental Adaptability: The PR6423 sensor features a stainless steel enclosure, IP67 protection rating, and can withstand harsh industrial environments ranging from -40°C to 85°C.
- Measurement Principle: Utilizing the non-contact eddy current principle, changes in distance between the sensor probe and the rotating shaft surface are converted into voltage or current signals.
- Signal Output:Typically, the output is a voltage signal proportional to the displacement (e.g., 8 V/mm).
- Physical Connection: The sensor is connected to CON021 via a dedicated cable (typically a 4-core shielded wire).
- Certification: The product has the CE mark and is ISO quality certified.
- Explosion-proof Safety: The "-CN" suffix for the Chinese market typically indicates compliance with Chinese national explosion-proof standards (GB standards) or relevant regulations, making it suitable for explosive gas environments.
- Material Compliance: The sensor chain is pre-calibrated for commonly used materials in turbine machinery (such as 42CrMo4/SAE 4140 steel) to ensure measurement accuracy meets industry standards.
