Product Introduction
The Epro PR6426/010-110 + CON021/916-120 Eddy Current Sensor is a premium-grade industrial sensor designed for non-contact measurement of shaft displacement, vibration, and axial position in rotating machinery. With a 32mm sensing diameter, it ensures reliable detection of minute movements and vibrations in turbines, compressors, pumps, and other critical equipment. When paired with the CON021 signal converter module and configured with the 916-120 extension cable, this sensor system delivers precision measurements under extreme industrial conditions.
The PR6426 series is well-regarded for its long service life, robustness in harsh environments, and compatibility with various condition monitoring systems, including Bently Nevada and Epro VM600.
