Proximity Sensor Model: 9200 - Two-Wire Seismoprobe Velocity Transducer Bently Nevada 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. For most installations, Bently Nevada's Velomitor family of velocity transducers, which incorporate solid- state technology, provide improved performance and ruggedness for casing velocity measurement applications.
