EPRO PR9376/010‑011 | Hall-Effect Sensor with Signal Converter

Emerson EPRO PR9376/010‑011 + CON021 Hall‑Effect Speed/Proximity Sensor

Product Overview

The Emerson EPRO PR9376/010‑011 + CON021 is a high-performance Hall-effect speed and proximity sensor system. It combines a 14 mm non-contact sensor with a signal converter, providing precise shaft displacement, rotational speed, and gear tooth detection. Moreover, the system ensures fast transient response and robust protection, making it ideal for critical turbomachinery applications. Therefore, it is widely used in turbines, compressors, pumps, fans, and industrial gearboxes for API 670-compliant monitoring.
