PR6423/003-030-CN EPRO Eddy Current Proximity Probe
PR6423/003-030-CN is an 8mm EPRO eddy current proximity probe within PR6423 series. It comes with a 3-meter integrated PTFE high-temperature coaxial cable with bare wire ends, and the -CN suffix represents China-region cable & connector configuration. This non-contact probe is designed for Turbine Supervisory Instrumentation (TSI) systems to measure radial shaft vibration, axial thrust displacement, shaft eccentricity and dynamic rotor position for critical rotating machinery.
Manufactured under EPRO (Emerson) industrial standards and fully compliant with API 670 turbomachinery protection requirements, PR6423/003-030-CN delivers high linearity and stable analog gap signals. Based on eddy current measuring principle, there is no physical contact between PEEK probe tip and metal rotor surface, eliminating mechanical wear and supporting continuous 24/7 long-term operation in power, oil & gas and petrochemical harsh industrial environments. This probe must pair with CON021 or CON031 signal converter (proximitor) to form a complete measurement system.

H2:Typical Applications
PR6423/003-030-CN eddy current probe is widely used 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 process industry
- TSI turbine supervisory system, machinery protection, predictive maintenance and fault diagnosis
It continuously collects real-time shaft dynamic movement data and transmits signals to TSI monitoring modules. When vibration or thrust displacement exceeds preset alarm thresholds, the system triggers alarm or trip interlock to prevent catastrophic equipment failure and reduce unplanned downtime.

H2:FAQ
H3:What is PR6423/003-030-CN?
PR6423/003-030-CN is an 8mm EPRO eddy current proximity probe with 3m bare wire cable and CN cable configuration. It measures shaft vibration and displacement for TSI turbine protection systems and must work with CON021 or CON031 proximitor.
H3:What does CN suffix mean on PR6423/003-030-CN?
The -CN suffix stands for China region cable and connector assembly. It maintains identical measurement performance as standard PR6423/003-030 probe, optimized for local site installation.
H3:Can PR6423/003-030-CN pair with CON021?
Yes. PR6423/003-030-CN is compatible with CON021 signal converter. The probe and proximitor set need calibration matching before field installation.
