PR6423/001-000+CON021 is a full factory-matched EPRO eddy current proximity measuring system, including the PR6423/001-000 5mm diameter eddy current probe and CON021 proximitor (signal converter). Designed for Turbine Supervisory Instrumentation (TSI), this non-contact sensor set measures shaft radial vibration, axial thrust displacement, shaft eccentricity and dynamic shaft position for critical rotating machinery.
Built to EPRO (Emerson) quality standards and API 670 machinery protection specification, this 5mm probe kit delivers high linearity and stable dynamic measurement signals. The eddy current working principle avoids physical contact between probe tip and metal shaft, eliminating mechanical wear and supporting continuous 24/7 operation in power, oil & gas and petrochemical harsh working environments. The full set is pre-calibrated as a matched pair for best measurement accuracy.

H2：Typical Applications
PR6423/001-000+CON021 eddy current sensor kit is used for protection and condition monitoring of critical rotating equipment:
Steam turbine, gas turbine, hydro turbine
Centrifugal compressors, large gearboxes
Heavy-duty industrial pumps, induced draft fans
Thermal power plants, oil & gas, petrochemical process plants
TSI turbine supervisory system, machinery protection, predictive maintenance and fault diagnosis
It continuously monitors real-time shaft movement and sends signals to TSI monitoring modules. When vibration or thrust displacement exceeds preset thresholds, the system triggers alarm or trip signals to prevent catastrophic equipment failure and reduce unplanned downtime.

H2：FAQ
H3：What is PR6423/001-000+CON021?
PR6423/001-000 is a 5mm EPRO eddy current probe, paired with CON021 proximitor. The full set is used for non-contact shaft vibration and displacement measurement in TSI turbine protection systems.
H3：Why choose 5mm PR6423/001 series probe?
5mm small diameter design fits tight installation space where standard 8mm probes cannot be mounted. It maintains API670 measurement performance for turbomachinery monitoring.
H3：Is this set factory calibrated?
We supply matched probe and proximitor set. Factory calibration certificate can be provided upon request.
