PR6423/003-031-CN+CON041 EPRO 8mm Eddy Current Probe & CON041 Kit

PR6423/003-031-CN+CON041 is a factory-matched EPRO eddy current proximity measurement system, including PR6423/003-031-CN 8mm eddy current probe with 3m CN configured coaxial cable and CON041 signal converter (proximitor). This non-contact sensor system is designed for Turbine Supervisory Instrumentation (TSI) and machinery condition monitoring, delivering high-precision measurement of radial shaft vibration, axial thrust displacement, shaft eccentricity and dynamic rotor position for critical rotating machinery.

Manufactured to EPRO (Emerson) industrial standards and fully compliant with API 670 turbomachinery protection requirements, this matched kit provides high linearity and reliable signal conversion. Unlike CON021, CON041 supports both voltage and 4-20mA analog outputs, enabling direct integration with PLC and DCS systems. The eddy current measuring principle avoids physical contact between PEEK probe tip and metal rotor surface, eliminating mechanical wear and supporting continuous 24/7 operation in power, oil & gas and petrochemical harsh industrial environments. The -CN suffix stands for China-region cable & connector configuration.

H2：Typical Applications

PR6423/003-031-CN+CON041 eddy current sensor kit is deployed for condition monitoring and protection of critical rotating assets:

• Steam turbine, gas turbine, hydro turbine
• Centrifugal compressors, screw compressors
• Large industrial pumps, induced draft fans, gearboxes
• Thermal power plants, oil & gas, petrochemical processing plants
• TSI turbine supervisory instrumentation, machinery protection, predictive maintenance and fault diagnosis

It continuously captures real-time shaft dynamic movement and transmits analog voltage or 4-20mA signals to TSI racks, DCS or PLC. When vibration or thrust displacement exceeds preset alarm thresholds, the system triggers alarm or trip interlock to avoid catastrophic equipment failure and reduce unplanned downtime.

H2：FAQ

H3：What is PR6423/003-031-CN+CON041?

PR6423/003-031-CN is an 8mm EPRO eddy current probe with 3m CN cable configuration, paired with CON041 proximitor. This full matched kit measures shaft vibration and displacement for TSI and DCS machinery monitoring systems.

H3：What is the difference between CON041 and CON021?

CON041 provides both gap voltage and 4-20mA current output, which can directly connect to PLC/DCS, while CON021 only outputs gap voltage for MMS TSI racks. Both are compatible with PR6423 series probes.

H3：Is this complete set factory calibrated?

This is factory matched probe and CON041 assembly. Factory calibration certificate can be provided upon customer request.
