Product Introduction
The Epro PR6424/010-140 + CON021 is a high-precision, non-contact eddy current displacement sensor, specifically designed for continuous vibration and axial position monitoring of rotating machinery. Developed by EPRO (a renowned brand in condition monitoring and machine protection), this sensor is part of the PR6424 series, known for its reliability in harsh industrial environments.
This model comes with a 16mm diameter probe and a CON021 converter, making it suitable for turbine machines, compressors, gearboxes, and pumps. The sensor functions on the principle of eddy current, providing accurate real-time data on shaft displacement, vibration amplitude, and position.
It is compatible with EPRO’s MMS 6000, 3000 series, and other machine monitoring systems, making it a favored choice for retrofitting or upgrading older systems with modern, high-resolution sensing capabilities.
