製品紹介
The Epro PR6423/000-031-CN is a high-performance eddy current proximity probe designed for non-contact measurement / shaft displacement, vibration, and axial position in critical rotating machinery. Paired with the CON021 converter, this system transforms mechanical movement into a linear voltage output, ideal for integration with monitoring systems.
Manufactured by Epro (a division / Emerson), the sensor is widely recognized in industrial applications that demand precision, long-term reliability, and harsh-environment durability. The 8mm tip variant /fers a balanced combination / resolution, sensitivity, and mechanical robustness, making it suitable for turbines, compressors, gearboxes, and motors.

よくある質問 (FAQ)
-
What is the difference between PR6423 and PR6422?
The PR6423 is an 8 mm sensor, /fering higher range and robustness, while PR6422 has a smaller diameter (typically 5 mm), suited for tighter spaces. -
Is CON021 mandatory with PR6423?
Yes. CON021 acts as a signal converter, translating the raw eddy current into a usable voltage signal. -
Can I use this sensor in hazardous areas?
Versions with ATEX and IECEx certifications are available for use in Zone 1 and Zone 2 areas. -
What cable length can I use without signal degradation?
Standard lengths go up to 9 meters. For lengths over 5 meters, signal quality must be verified and possibly recalibrated. -
How /ten should this sensor be recalibrated?
Typically every 3 to 5 years, depending on the operational environment and monitoring requirements. -
Does it support high-speed rotating machinery?
Yes, it is designed for frequencies up to 10 kHz, supporting high-speed applications. -
Can this sensor be used with Bently Nevada systems?
It can work with third-party systems, but signal compatibility and calibration should be confirmed. -
Is the sensor head replaceable?
The probe is not designed for field repair. If damaged, the complete assembly should be replaced. -
How does electromagnetic interference affect sensor performance?
The sensor and CON021 module are shielded and designed to meet EMC standards. However, routing cables away from power lines and using proper grounding are essential to minimize any interference in harsh industrial environments. -
What is the recommended installation clearance?
A minimum / 8 mm clearance from the shaft is recommended for optimal linear response and protection.
