製品紹介
The Bently Nevada 190501-01-00-00 Velomitor CT is a compact, industrial-grade seismic velocity transducer designed for accurate measurement / casing vibration in rotating and reciprocating equipment. As part / the renowned Velomitor® CT Series, this sensor incorporates a piezoelectric sensing element with built-in signal conditioning to produce a directly usable output signal proportional to velocity.
Unlike traditional velocity transducers that rely on moving coil mechanisms, the Velomitor CT uses solid-state technology, resulting in greater reliability, better frequency response, and higher resistance to environmental challenges such as shock, vibration, and moisture. It is engineered for continuous condition monitoring and machinery protection in harsh environments, making it a reliable choice for asset management systems in power, oil and gas, pulp & paper, and general industrial sectors.
