Meggitt Vibro-Meter CV211 Velocity Transducer

Velocity TransducerVelocity transducers CV213 and CV214DESCRIPTION (continued) The transducer’s sensing element consists of a coilmoving around a permanent magnet. This assembly produces a voltage directly proportional to the vibrationvelocity. The signal is generated without the need for an external power source, a feature that makes thesedevices suitable for portable measurement applications.industrial environments, the transducer should be installed with its cable assembly covered by a flexibleprotection tube (sheath) made of metal, for mechanical protection.For specific applications, contact your nearest Meggitt Sensing Systems representative.Dedicated cable assemblies are available for each velocity transducer. The ED120 assembly is intended forthe CV213 and the ED121 for the CV214.
