PR6423/002-030-CN+CON021 is a fully factory-matched EPRO eddy current proximity measurement assembly, including PR6423/002-030-CN 8mm eddy current probe (CN cable & connector configuration) and CON021 proximitor signal converter. This non-contact sensor system is designed for Turbine Supervisory Instrumentation (TSI), delivering accurate measurement of shaft radial vibration, axial thrust displacement, shaft eccentricity and dynamic rotor position for critical rotating machinery.
Built to EPRO (Emerson) quality standards and fully compliant with API 670 turbomachinery protection specifications, the matched kit provides high linearity and stable analog gap voltage signals. The eddy current working principle eliminates physical contact between probe tip and metal shaft surface, removing mechanical wear and enabling reliable 24/7 continuous operation in power, oil & gas and petrochemical harsh industrial environments. The CN suffix denotes China regional cable assembly, pre-calibrated as a complete measurement chain.

H2:Typical Applications
PR6423/002-030-CN+CON021 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 signals to TSI monitoring modules. 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.
