Product Introduction
The Epro PR6424/010-000+CON021 is an industrial-grade eddy current displacement sensor designed for accurate non-contact measurement of shaft position, vibration, and displacement. This sensor belongs to Epro’s highly respected PR6424 series, developed for use in demanding monitoring environments such as rotating machinery in power generation, oil & gas, and heavy industrial systems.
This specific model is fitted with a 16mm probe tip diameter, making it ideal for large shaft diameters and longer measuring distances. It comes paired with the CON021 converter, which ensures seamless signal processing and compatibility with various monitoring systems such as MMS6000, MMS3000, and VM600. Thanks to its robust construction and high-temperature tolerance, the PR6424/010-000+CON021 is trusted for critical applications where operational reliability and diagnostic accuracy are paramount.
