Epro PR6480/3D1-000 Eddy Current Sensor

产品介绍

The Epro PR6480/3D1-000 Eddy Current Sensor is a high-performance non-contact displacement and vibration measurement probe, designed specifically for industrial environments where precision, reliability, and durability are critical. As part / the Epro PR6480 series, this model embodies advanced German engineering that ensures accurate and repeatable measurements even in harsh operating conditions such as high temperature, pressure, and vibration.

The sensor operates on the eddy current principle, detecting changes in the distance between its sensing head and a conductive target surface. These changes are converted into proportional voltage signals through compatible Epro converters, such as CON011, CON021, or CON031. This combination provides high-resolution measurements for shaft displacement, axial movement, and vibration amplitude in rotating machinery.

Built with a stainless-steel probe body and sealed to IP67, the PR6480/3D1-000 is suitable for long-term use in oil-contaminated and corrosive environments. It complies with API 670 and ISO 10817 standards, making it an ideal choice for machine protection systems in power generation, petrochemical, and industrial manufacturing sectors.
