Epro CON011+PR6426/010-140 Eddy Current Sensor

Product Description

The PR6426/010-140 + CON011 system from Emerson Epro is a heavy-duty eddy-current sensing solution engineered for precise, non-contact measurement of shaft movement and vibration in large rotating equipment. The system integrates a robust 32 mm probe with a signal conditioning converter, delivering stable and calibrated outputs suitable for continuous condition monitoring and machinery protection.

Designed for harsh industrial environments, this configuration supports accurate detection of radial and axial displacement, making it a reliable choice for turbomachinery diagnostics and predictive maintenance programs.
