Ultrasonics

With specialized ultrasonic equipment, coservices has the capability to detect leaks in steam and air lines, gas lines, vacuums and detects mechanical faults in bearings and steam traps.

Technically, ultrasounds are sounds that cannot be heard by the human ear. In other words, sounds with a frequency above 20 kHz. Ultrasounds have a number of specific characteristics that make them useful in industrial applications.
Ultrasounds can be very precisely measured. Differences in intensity as the waves travel through a medium or body can be quantified. So various phenomena that can influence the working and quality of machines and systems adversely can be clearly identified - often without interrupting their operation.
High frequency sounds are also more directional than lower frequency. This makes it easier to pinpoint the source even in the presence of other background noise.
The other major benefit of ultrasounds is the sheer number of things that produce them. Leaks, stress, electrical discharges, cavitation (the appearance of cavities filled with damp and gas) in flowing liquids, turbulence in flowing gas or liquids; each emits ultrasounds that can be detected and measured.


Ultrasonic detection and measurement can often be carried out relatively simply. The basic set-up in control situations consists of a hand-held unit with headphones, a meter, a sensitivity adjustment and one of a number of nozzles or modules. Some applications also require a transmitter.
