Product Introduction
The Epro CON021/916-200+PR6426/000-130 is a 32mm Eddy Current Sensor specifically engineered for precision monitoring of displacement, vibration, and position in industrial machinery. This sensor integrates the PR6426/000-130 measurement head with the CON021/916-200 signal conditioning unit, providing reliable, high-resolution, non-contact measurements.
The PR6426/000-130 head operates using the eddy current principle, detecting minute variations in conductive target distances and converting them into a proportional electrical signal. Coupled with the CON021/916-200, the system produces stable, linear, and repeatable outputs suitable for feedback control, diagnostics, and predictive maintenance in critical rotating machinery.
Designed for harsh industrial environments, the sensor can tolerate temperature fluctuations, vibration, and electromagnetic interference without compromising accuracy. Its compact and robust design allows installation in tight spaces while maintaining optimal measurement integrity.
