Technical Data SheetStructure-Borne Sound Probe T20 The Structure-Borne Sound Probe T20 is used for condition monitoring of machines, plants and processes where detectable structure-borne sound in the ultrasonic range is generated. Changes in the sound signals indicate a change in the condition and/or process of the test object. The detection of these changes forms the basis for condition monitoring in preventive maintenance. The Structure-Borne Sound Probe T20 is used when installation space is limited and the machine surface or test point is preferably magnetic. The type of coupling depends on the type of test. For recurring measurements with recording of measurement data, the probe can be fixed with a magnetic base or universal magnet. For permanent monitoring or fixed mounting within a safety cover/zone, the probe is screwed on with a grub screw.
