Control 201630th anniversary of the trade fair
Over 900 exhibitors from 32 countries are expected at Control from April 26 to 29, 2016. The world's leading trade fair for quality assurance is celebrating its 30th anniversary this year.
Selasco will be presenting a system for non-contact and non-destructive wear and defect diagnosis of units during operation. With the help of a laser beam, characteristic sound spectra of a unit to be monitored (e.g. high-performance pump, motor, gearbox, machine, drive unit, turbine) are recorded in a frequency range from infra- to ultrasound in the MHz range using interference measurements. The structure-borne sound generated during operation is then analyzed using mathematical algorithms. Level differences between the current evaluated signal and a reference signal are intended to indicate a material defect in the monitored component. According to the manufacturer, this enables material changes to be detected at an early stage and total failure to be avoided.
