Product Overview: Epro PR6424/002-131 + CON031 16mm Eddy Current Sensor with Signal Converter
The Epro PR6424/002-131 combined with the CON031 Signal Converter forms a high-precision, non-contact eddy current measurement solution designed for critical rotating machinery monitoring. This sensor assembly is widely deployed in turbomachinery like gas turbines, steam turbines, hydro turbines, pumps, compressors, and fans for monitoring shaft dynamic displacement, eccentricity, position, speed, and key phasor signals.
The PR6424 sensor offers a shaft non-contact measurement solution with a nominal sensitivity of 4 V/mm, designed to work in harsh environments with high reliability. The CON031 signal converter complements this sensor, providing high-speed signal processing with excellent linearity and low noise.
