Velocity Transducers

Sensonics offer a range of both piezo electric and moving coil velocity transducers (Velometer®) for applications requiring a vibration velocity signal direct from the sensor. These transducers are particularly suitable for applications requiring high sensitivity or for use in high electrical noise environments where integration of an accelerometer signal in the vibration monitor is not preferred due to unwanted signals induced on interconnecting cables. The moving coil type of velocity transducer is sometimes preferred for steam turbine bearing measurement applications where steam noise can saturate the output of piezoelectric accelerometers. A summary of the velocity transducer product range is detailed below.
