Bently Nevada 74712-06-01-03-00 Seismoprobe Velocity Transducer Systems are designed to measure absolute (relative to free space)bearing housing, casing, or structural vibration. The two-wire systems consist of a transducer and appropriate cable.
The Seismoprobe family of velocity transducers is a two-wire design that uses moving-coil technology. It provides a voltage output directly proportional to the transducer's vibration velocity.
Moving-coil transducers are less sensitive to impact or impulsive excitation than solid-state velocity transducers, which are inherently accelerometers with embedded integration electronics. Moving-coil transducers are less sensitive to impact or impulsive excitation and can represent a good choice for certain applications. Because they don’t require external power, they are convenient for portable measurement applications.
