Download SDT170S/S+ Spec Sheet

AVM Ultranalysis is a system developed by SDT for recording ultrasound sound files for training, maintaining a library of your factory's sounds, and for further analysis in the TIME and SPECTRUM domain.

The SDT170 captures ultrasonic signals from machines, bearings, electrical systems, steam traps, and other factory phenomena. These ultrasound signals are presented audibly through the 1/4" headphone jack. Ultrasound inspectors listen to these signals through noise attenuating headphones. But what if we could see what we hear?

Ultrasound files are saved as .wav files by a digital recorder (preferably not MP3) and uploaded to PC. AVM Ultranalysis is a sound analysis software with many features for analyzing .wav files. Ultrasound inspectors can determine several things now.

For instance, electrical inspectors can look at the FFT of a captured electrical sound file and determine if the problem is related to corona or more serious tracking and arcing. All forms of partial discharge can be analyzed in this way.

Mechanical inspectors can compare vibration spectra and ultrasound data to confirm their diagnosis. This is a great way to determine the condition of slow speed bearings.

Reciprocating compressor valves can also be examined using this method. Dirty valves, poorly seated valves, and valves that are leaking can be identified.
