Product Introduction
The Epro PR6423/002-001-CN combined with the CON021 converter is a robust, industrial-grade eddy current sensor system developed for high-precision, non-contact displacement and vibration measurements. Specifically designed to monitor rotating machinery such as turbines, compressors, motors, and pumps, this 8mm probe provides real-time data crucial for predictive maintenance and machinery protection in demanding environments.
This particular model – PR6423/002-001-CN – offers an 8mm probe tip diameter and is optimized for metallic surface monitoring. It integrates seamlessly with the CON021 converter, which conditions and amplifies the sensor signal, delivering accurate voltage output proportional to the distance between the probe and the monitored surface. The probe is tailored for Chinese specifications (hence the “CN” suffix), ensuring compliance with local standards and industrial compatibility.
