Bently Nevada 190501-00-99-01 Velomitor CT Velocity Transducer

Product Introduction

The Bently Nevada 190501-00-99-01 is a Velomitor CT velocity transducer designed for direct vibration velocity measurement in industrial rotating and reciprocating machinery. Unlike proximity probes that measure displacement, this sensor provides true velocity output, making it especially effective for monitoring casing vibration and overall machine condition.

As part of the Velomitor CT series, this transducer integrates sensing electronics within the housing, delivering a conditioned signal suitable for long cable runs and harsh environments. It is widely used in applications where shaft access is limited or where machine casing vibration is the primary diagnostic indicator.
