The EPRO CON021 + PR6423/000-031 system offers precise, non-contact eddy current sensing. Engineers use it to measure shaft displacement, position, and vibration in rotating machinery like turbines, compressors, and pumps. Consequently, it plays a critical role in condition monitoring and machinery protection across power generation and heavy industry.
