Description
Emerson PR9268/301-000 is an electro-dynamic absolute vibration transducer designed to measure vibration velocity using the seismic measurement principle. A suspended measuring coil acts as the seismic mass, remaining stationary above the resonance frequency while the housing follows machine movement. This relative motion generates a voltage signal proportional to vibration velocity, ensuring reliable monitoring of rotating equipment. Emerson PR9268/301-000 operates within a frequency range of 4 Hz to 1000 Hz, making it suitable for a wide spectrum of industrial applications. Its nominal sensitivity of 28.5 mV/(mm/s) provides consistent signal output for precise diagnostics. The transducer supports horizontal measurement orientation for applications up to 100°C.
