2.5 Device function
2.5.1 Intended use
The SONOCHEK is a measuring device for detecting, recording and evaluating ultrasonic
signals (regarding functionality, see chapter 2.5.3).
Ultrasound can occur in a variety of processes, such as:
in the event of leaks on compressed air, steam and vacuum systems,
when operating condensate drains,
at leaky valves, slides, shut-off devices or taps in piping systems,
when working on sliding or roller bearings,
in the event of cavitation caused by pumps and compressors
in the case of flashover or corona discharges on electrical systems.
Any use other than the intended use is prohibited and may lead to personal injury or physical
damage. PRUFTECHNIK is not liable for damage, also to third parties, caused by the improper
handling of the device.
2.5.2 Functional Scope
The SONOCHEK can be used to evaluate system conditions where ultrasonic signals occur and
whose evaluation allows for conclusions to be drawn about the correct functioning. Applications
range from the "simple" leak check to the monitoring tasks of complex processes. The device
concept of the SONOCHEK was developed with the aim of using adapted sensor systems and
flexibility in data output for the user to support an optimal evaluation for many different
processes.
The basis of the system is formed by the mobile measuring device, which has a sensor
connection and interfaces. Functional and application software is installed on the device. The
SONOCHEK apps already contain powerful functionalities for measurement, recording and
display.
Many basic tasks can already be realized with these apps:
Planning measurement tasks
Recording signal sequences
Saving and replaying signal sequences
Making ultrasonic signals audible
Documenting (photographing) measurement points, marking damage points

SONOCHEK 09.2018
2.5.3 Functional principle
Ultrasonic signals are generated in a multitude of processes in different frequency ranges,
which are made visible and audible with the SONOCHEK.
Two types of ultrasound are distinguished between with respect to the use of sensors for
investigations with the SONOCHEK:
Airborne sound – the sound waves spread through the air; detectable when looking for leaks
on compressed air lines, for example
structure-borne sound – the sound waves occur during mechanical processes, spread in solid
bodies and can be used, among other things, to detect bearing wear
The SONOCHEK can be used to evaluate ultrasonic signals, which inevitably occur during the
considered processes (leaks in compressed air or vacuum systems). Alternatively, the
SONOCHEK can detect ultrasonic signals, which are actively generated by a corresponding
transmitter. This procedure is used, for example when measuring the leak tightness of pressure-
free systems and containers.
Averaging the ultrasound in very small time intervals produces the representation of the level
profile. The level data is output as a level profile. The spectra are calculated directly from the
high-resolution ultrasonic data and displayed as spectra over time (spectrogram). Up to 5
additional level values can be output via the display according to individual requirements.
At the same time, the signals are made audible via the speakers integrated in the unit or via
headphones (for working in areas with high ambient sound levels). The volume can be
controlled via buttons on the device or on the sensors.
For the documentation, voice memos can be recorded and text comments can be stored for
each measurement. Furthermore, photos can be taken on which the damage points can be
marked.
PDF reports can already be created in the device by using the stored data and the additional
information. It is possible to transfer all data (individual data as well as reports) to other devices
via the USB interface for further processing.
