Product Description
PR6423/000-000 6140-00031 is EPRO eddy‑current converter unit from Emerson. It forms complete shaft‑vibration measurement chain together with PR6423 probe and extension cable, compatible with AMS6500 A6140 machinery protection module. It converts high‑frequency probe oscillation signal into linear voltage output for relative shaft vibration, shaft displacement, eccentricity and key‑phasor speed measurement. Built‑in supervision for probe open‑circuit / short‑circuit fault detection, compliant with API‑670. Metal‑cased for cabinet DIN‑rail mounting, widely deployed for turbines and compressors. OEM end‑of‑life, supplied as legacy maintenance spare partEmerson。

Product Application
- Turbine shaft‑vibration monitoring: Measure relative shaft vibration and displacement for steam & gas turbines, feed signals to AMS6500 protection system.
- Compressor machinery protection: Continuous rotor‑condition monitoring for compressors, large pumps and fans.
- Proximity‑system spare‑part replacement: Direct swap‑out for defective CON011 converter to restore full eddy‑current measurement loop.
- MMS6000 legacy‑system retrofitting: Drop‑in spare for older EPRO MMS6000 machinery‑monitoring frames.
- Plant spare‑parts inventory: Standby spare for power‑plant & petro‑chemical critical rotating‑asset protection, minimize unit‑downtime.
