The EPRO PR6423/222-110 is a premium eddy current transducer designed for critical rotating equipment. This complete system measures radial vibration and axial position with high accuracy in turbines, compressors, and large pumps. It forms an integral part of the industry-trusted EPRO MMS 6000 and PR 6423 series for predictive maintenance.
Measurement Principle and System Integration
This transducer operates by generating a precise electromagnetic field from its probe tip. A conductive target, like a machine shaft, alters this field linearly with distance changes. The PR6423/222-110 then converts this change into a stable -2 to -18 V DC signal for the monitoring system.
The system requires a compatible CON series oscillator and converter unit to power the probe and condition the signal. This integrated approach ensures optimal performance, high noise immunity, and reliable data over long cable runs back to the control room.
Robust Physical Design and Components
The EPRO PR6423 features a rugged stainless steel probe housing for durability in harsh environments. Its specific suffix /222-110 defines a complete kit including the probe, extension cable, and connector. The probe’s standard 8mm or 11mm diameter suits most industrial mounting holes and provides a defined measurement range.
Each kit contains precisely one transducer probe and one matching cable assembly, with no internal batteries or stored energy. This passive design guarantees a long service life and minimal maintenance under extreme temperatures and pressures.
