What a Korean refinery learned about reciprocating compressor monitoring
A Bently Nevada case study: why frame vibration alone cannot diagnose a reciprocating compressor, and what cylinder pressure and rod position add.
Sensors, Accelerometers and Velomitors
Industrial accelerometers and Velomitor velocity sensors for casing and bearing-housing vibration measurement on a wide range of machinery.
Bently Nevada seismic transducers measure absolute vibration of machine casings, bearing housings and structures where non-contact shaft measurements are not sufficient or not possible. The range covers general-purpose and high-temperature accelerometers as well as Velomitor piezo-velocity sensors.
Accelerometers provide a wide frequency response ideal for detecting rolling-element bearing defects, gear mesh problems and blade-pass phenomena. Velomitor sensors output velocity directly, simplifying integration with monitors and aligning with traditional velocity-based alarm criteria.
All sensors are available with hazardous-area approvals, a choice of connector and cable options, and matched mounting hardware for reliable installation in demanding environments.
