Product Introduction
The Bently Nevada 190501-09-99 Velomitor CT Velocity Transducer is a high-precision vibration velocity sensor designed for direct measurement of casing vibration in industrial machinery. As part of the well-known Velomitor series, this model provides a self-generating voltage output proportional to vibration velocity, eliminating the need for external power sources or signal conditioning devices.
It is engineered specifically for use on compressors, pumps, turbines, gearboxes, and other rotating equipment where continuous monitoring of casing vibration is essential for condition-based maintenance and protection systems. The Velomitor CT design ensures exceptional reliability in harsh operating environments with high temperatures, oil mist, or mechanical shock.
The transducer features a 33 mm sensor diameter and compact cylindrical housing, allowing easy installation in confined industrial spaces. The sensor’s sealed stainless-steel body ensures resistance to moisture, corrosion, and electromagnetic interference. With a weight of 0.297 kg, it offers a balance between ruggedness and lightweight design for flexible mounting.
