PR9268/617-100N Emerson Epro Electrodynamic Velocity Sensor
Description:
PR9268 offers several basic types to cover a wide range of industrial measuring applications.    

The measuring element of the absolute bearing vibration sensor PR 9268 consist of a seismic mass with a coil,  suspended on membrane springs and moving in the circular gap of a permanent magnet. The membrane springs lead the measuring element in the longitudinal direction (=measuring direction).      

The sensors are operated above the resonance frequency, which is between 4 and 13 Hz, depending on the type. The seismic mass remains at rest and due to the vibration of the sensor housing, an electric signal proportional to the vibration velocity is generated.   

PR9268/617-100N is Electrodynamic Sensors without Armored cable.
