Product Overview
The EPRO PR6423/003‑030‑CN is a non‑contact eddy‑current proximity probe engineered for shaft vibration, axial displacement and position measurement on high‑speed rotating machinery. This passive sensor works paired with a CON021 signal converter to convert clearance variation between probe tip and conductive metal shaft into proportional analog voltage output. It resolves typical rotating‑asset monitoring challenges including indirect casing‑mount measurement inaccuracy, high‑temperature operating limits and signal drift caused by mechanical vibration. Machinery protection engineers, plant condition‑monitoring technicians and maintenance teams gain value from this sensor; direct non‑contact shaft measurement captures true rotor motion hidden by bearing oil‑film damping, delivering reliable early‑warning data for predictive maintenance. It complies with API 670 machinery‑protection standards and supports installation within hazardous classified zones, fitting both new machinery‑protection system builds and spare‑part replacement for existing turbine and compressor assets.
Application Scenarios
- Steam & Gas Turbine Shaft Vibration Monitoring: Mounted through bearing housings to measure radial shaft vibration. Captures real‑time rotor dynamic movement for machinery protection systems, detecting unbalance, misalignment and rubbing events before serious equipment damage occurs.
- Centrifugal Compressor Axial‑Thrust Position Surveillance: Deployed for thrust‑bearing position monitoring. Tracks axial rotor excursion; provides continuous position data for protection logic to trigger alarms or trips when thrust bearing wear exceeds safe thresholds.
- High‑Temperature Process Fan & Blower Condition Monitoring: Suited for hot‑running rotating equipment. The wide probe operating‑temperature range maintains measurement stability without additional cooling hardware for high‑process‑temperature machinery.
- Retrofit of Legacy Machinery Protection Systems: Used as drop‑in field‑sensor spare for existing EPRO monitoring racks. Matched mechanical thread form and electrical characteristics reduce modification work during field‑sensor replacement and shorten plant downtime.
