Ultrasound detection uses acoustic crystals to convert and step down
sounds from the ultrasonic range into human hearing range.  

So, if you can hear the sound, the SDT unit is deaf.  

But if the sound is occurring above human hearing, then the SDT170 will
be singing out loud.  Now you have the ability to hear more of what is
really going on in your facility.
Many different warning signals give off ultrasonic sound.  In the airborne
environment, leaks of compressed gas or air can generate significant
ultrasonic sound.  

If you have leaks you can hear, then there are many more leaks that just
aren't big enough for you hear.  If you don't hear leaks, but your
compressors run when demand is off peak.  Then you have leaks.

Electrical arcing, tracking and corona generate ultrasonic sound
immediately.  You do not have to wait for the condition to worsen so
excess heat brings a thermal difference that an IR camera can pick up.

Using contact probes or magnet sensors, you can perform structure
borne ultrasound detection.  This is used extensively for monitoring
bearing conditions, traps, valves and to perform acoustic lubrication for
proper grease application.
