Bently Nevada Seismoprobe Velocity Transducer Systems are designed to measure absolute vibration (relative to free space) in bearing housings, casings, or structural components. These two-wire systems consist of a transducer and a compatible cable.
The Seismoprobe family of velocity transducers features a two-wire design that utilizes moving-coil technology, generating a voltage output directly proportional to the transducer’s vibration velocity.
Compared to solid-state velocity transducers, which function as accelerometers with embedded integration electronics, moving-coil transducers are less sensitive to impact or impulsive excitation. This characteristic makes them a reliable choice for specific applications. Additionally, since they do not require external power, they are particularly suitable for portable measurement applications.
