R6423/003-030+CON021 EPRO Eddy Current Probe & CON021 Proximitor Kit

H1：PR6423/003-030+CON021 EPRO Eddy Current Probe with CON021 Signal Converter

PR6423/003-030+CON021 is a factory-calibrated full EPRO eddy current proximity measurement system, consisting of PR6423/003-030 8mm eddy current probe with 3m bare-end PTFE coaxial cable and CON021 proximitor signal converter. Designed for Turbine Supervisory Instrumentation (TSI), this non-contact sensor set accurately measures radial shaft vibration, axial thrust displacement, shaft eccentricity and dynamic rotor position for critical rotating machinery.

Built to EPRO (Emerson) industrial standards and fully compliant with API 670 turbomachinery protection requirements, this matched kit delivers high linearity and stable analog gap voltage signals. Eddy current working principle avoids physical contact between PEEK probe tip and metal rotor surface, eliminating mechanical wear and supporting reliable 24/7 continuous operation in power, oil & gas and petrochemical harsh environments. The PR6423/003-030 features bare wire termination design for direct wiring to CON021 terminal block.

H2：Typical Applications

PR6423/003-030+CON021 eddy current sensor kit is 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 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.
