The 9200 family uses moving-coil technology to generate a voltage output directly proportional to vibration velocity. Baker Hughes describes the 9200 as suitable for continuous monitoring or periodic measurements with test or diagnostic instruments.

The transducer forms part of the vibration measurement chain. Installation location, orientation, mounting and the receiving instrument all affect the measurement.
Used for absolute vibration velocity measurement on machine housings or bearing locations.
A missing or unstable vibration signal can lead maintenance teams to search by the complete order code.
A failed sensor can remove a vibration measurement point from the monitoring chain.
