Product Description
The Epro PR6424/010-100 is a non-contact eddy current sensor designed to monitor radial and axial shaft displacement in critical rotating machinery. With a sensor head diameter of 16mm, it is part of Emerson’s renowned PR6424 series used extensively across the turbomachinery sector. Its robust stainless steel construction and high-temperature tolerance make it particularly suitable for harsh industrial environments such as steam, gas, and hydro turbines, compressors, and large-scale pumps.
This sensor provides highly accurate measurements of shaft position, vibration (dynamic displacement), eccentricity, and rotational speed when used with a suitable signal converter (e.g., CON011). The PR6424/010-100 variant offers armored cable protection and is commonly deployed in hazardous and high-vibration zones due to its ATEX, IECEx, and CSA compliance.
