Velocity Transducer System - GE Energy Bently Nevada - #1

Specifications and Ordering Information 9200, 74712 Seismoprobe® Velocity Transducer System

Bently Nevada Seismoprohe© Velocity Transducer Systems are designed to measure absolute (relative to free space) bearing housing, casing, or stnjctural vibration. The two-wire systems consist of a transducer, appropriate cable, and an optional velocity-to-displacement converter.

The Seismoprobe® family of velocity transducers are a two-wire design that uses moving-coil technology and provides a voltage output directly proportional to the transducer's vibration velocity. Unlike solid-state velocity transducers: which are inherently accelerometers with embedded integration electronics), moving-coil transducer; a's- less sensitive :o impact or impulsive excitation, and can represent a good choice for certain applications. Also, because they require no external power, they are convenient for portable measurement applications.

Velocity Transducers are

■ 9200: The 9200 is a two-wire transducer suitable force monitoring or for periodic measurements in conjunction with test or diagnostic instruments. When ordered with the integral cable option, the 9200 has excellent resistance to conosive environments without need of additional protection.

■ 74712: The74712lsahlghtemperatureverslonofthe9200.

Various interconnect cables are available for connecting the 9200 and 74712 transducers to other instruments or a velocity-to-displacement converter. These cables are available in one-foot (300 mm) increments, with or without
