Product Introduction
The Epro CON021/916-240 + PR6426/010-140 is a high-performance eddy current displacement sensor system, designed for use in critical rotating machinery monitoring such as turbines, compressors, and large industrial motors. This configuration integrates the PR6426/010-140, a 32mm diameter sensor probe, with the CON021/916-240 signal converter, offering robust signal conditioning for high-accuracy proximity measurement and vibration monitoring.
As part of the PR6426 series, this model is tailored for large gap and heavy-duty applications, especially in environments where non-contact precision, wide temperature tolerance, and reliable long-term operation are essential. When paired with the CON021 converter, the sensor delivers precise, stable, and interference-resistant output, ready for integration into condition monitoring and machine protection systems.
