Product Introduction
PR9268/203-000 is an electrodynamic vibration velocity sensor produced by EPRO in Germany. It is mainly used to measure the absolute vibration velocity of key rotating machinery (such as steam turbines, gas turbines, water turbines, compressors, pumps and fans). This sensor is widely used in vibration monitoring of industrial equipment, especially for real-time monitoring of the vibration state of rotating machinery to help predict equipment failures and perform preventive maintenance.
