The SKF TMSU 1 is a high quality, user friendly, sensitive instrument enabling the detection of air leaks by means of ultrasound. Leaks are caused by fluid flowing from a high pressure environment to a low pressure environment, creating turbulence. The turbulence generates high frequency sounds (so called ultrasound) that can be detected by TMSU 1. The sensitive piezoelectric crystal in the sensor allows the operator to quickly guide the instrument to the loudest point which helps locate the leak location.
