製品紹介
The Epro PR9268/302-100 is a robust and highly sensitive electrodynamic velocity sensor developed by Epro (a brand under Emerson). Engineered for the monitoring / vibration velocity in rotating machinery such as turbines, compressors, pumps, and motors, this sensor /fers excellent performance in harsh industrial conditions. Its analog output and electromechanical design make it ideal for detecting mechanical faults like imbalance, misalignment, and bearing defects.
Designed for direct installation on machine surfaces, the PR9268/302-100 delivers dynamic measurement signals proportional to vibration velocity, following ISO 10816/20816 standards. The sensor is completely passive, requiring no external power supply, and is widely used in machinery protection and predictive maintenance systems in industries such as power generation, oil & gas, chemical processing, and heavy manufacturing.
