instruments are sensitive to sounds beyond the
limits of normal human hearing.
An ultrasonic detector translates ultrasonic signals
to the range of human hearing. Ultrasound instrument
technology can tune-in to and "hear" faults
in electric transmission and distribution systems,
and in operating machinery, as well as leaks in vacuum
or pressurized systems.
Electrical systems, fluid and
gas systems, and working machinery all produce constant
Changes in the sonic signatures can be readily recognized
as loose connections, faulty equipment, or wear in
components. An ultrasonic detector senses subtle
changes in the ultrasonic signature of a component
and pinpoints potential sources of failure before
they can cause costly damage.
The most effective industrial
applications are detecting leaks in pressurized or
vacuum systems, inspecting steam traps, mechanical
analysis (especially bearings), inspecting valves,
and electrical corona or discharge detection.
