Vibration Monitoring Equipment specially designed for rotors or rotating equipment and machinery, capable of measuring any frequency in the range 600-2 000 Hz.

Vibration test systems, equipment and components thereof, other than those specified in 2B116: a. Vibration test systems employing feedback or closed loop techniques and incorporating a digital controller, capable of vibrating a system at an acceleration equal to or greater than 0,1 g rms between 0,1 Hz and 2 kHz and imparting forces equal to or greater than 50 kN, measured ‘bare table’; b. Digital controllers, combined with specially designed vibration test ‘software’, with a real-time bandwidth greater than 5 kHz designed for use with vibration test systems specified in a.; c. Vibration thrusters (shaker units), with or without associated amplifiers, capable of imparting a force equal to or greater than 50 kN, measured ‘bare table’, and usable in vibration test systems specified in a.; d. Test piece support structures and electronic units designed to combine multiple shaker units in a system capable of providing an effective combined force equal to or greater than 50 kN, measured ‘bare table’, and usable in vibration systems specified in a. Technical Note: ‘Bare table’ means a flat table, or surface, with no fixture or fittings.
