Emerson EPRO CON021+PR6423/010-000-CN Eddy Current Sensor

Designers created this Emerson EPRO CON021+PR6423/010-000-CN 8mm Eddy Current Sensor for critical turbomachinery applications, such as steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans. It measures both radial and axial shaft dynamic displacement, position, eccentricity, and speed.

This sensor offers precise, non-contact measurements for various critical turbomachinery applications and is particularly suitable for environments with high temperatures. It is designed to measure the displacement of shafts with a minimum diameter of 25 mm, typically made of ferromagnetic steel (42CrMo4), but it can also be adapted for use with other materials upon request. The sensor is well-protected with an IP66 rating and constructed from durable materials such as stainless steel, PEEK, and PTFE.
