Overview
The Emerson PR6423/004-010 proximity sensor delivers accurate non-contact displacement measurement across the PR6423 series and supports high-speed rotating machinery such as turbines, compressors, and motors. It maintains measurement stability across wide temperature ranges and offers rapid response for dynamic shaft behavior, which helps engineers diagnose machinery conditions with greater precision.
Key Features
- The Emerson PR6423/004-010 achieves a 0–10 mm sensing range that suits medium-to-large shaft displacement monitoring.
- It improves diagnostic accuracy because its 1 ms response time tracks rapid changes in shaft position.
- It maintains signal consistency since the linear output range remains within ±0.1% across the calibrated stroke.
- It supports reliable operation in industrial environments due to its stainless-steel construction and optimized thermal coefficient of 0.02%/°C.
