PR6423/003-110+CON021 EPRO Eddy Current Probe with CON021 Signal Converter

PR6423/003-110+CON021 is a factory-calibrated full EPRO eddy current proximity measurement system. It consists of PR6423/003-110 8mm eddy current probe with 3-meter integrated PTFE coaxial cable fitted with MIL-C-5015 5-pin connector, paired with CON021 proximitor signal converter. Designed for Turbine Supervisory Instrumentation (TSI), this non-contact sensor set delivers 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 stable analog gap voltage signals. The eddy current measuring 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 -110 suffix indicates 3m cable with MIL circular connector for quick plug-in installation.

H2：Typical Applications

PR6423/003-110+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 gap voltage 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.
