Overview
CRY2623 are hand-held industrial acoustic imager that support audible and
ultrasonic frequencies.
The instrument uses the microphone array beamforming technology to
acquire the sound source distribution data, and collects the video images in
real time with the high-definition camera. By integrating the sound source
distribution data with the video image, the changing sound source is
dynamically presented on the display screen.
CRY2623 Industrial Acoustic Imager helps you quickly detect potential
pressurized gas leaks and vacuum leaks in noisy industrial environments.Used
in power systems, it can help you quickly identify potential partial discharge
fault points.
The industrial acoustics imager is made of aluminum alloy shell, which is
strong and durable and can adapt to the complex and changeable working
environment.
The equipment is simple and convenient to operate, and can be used
quickly. It only needs to adjust two parameters, the test frequency range and
test dynamic range to meet the vast majority of test requirements.Support
camera mode, video mode,and the data recording on the job site is
flexible.Large capacity TF data memory card can be expanded, and test results
can be exported and reported quickly.

Terminology
USB Power Delivery (USB PD)
A power delivery protocol based on USB3.1,which is often used to transmit
more power in USB interface.
Sound Pressure Level (SPL)
A physical quantity used to express the magnitude of sound waves,the unit
is decibels (dB). It is also used as dBSPL.
Audible domain
The frequency range of sound that can be perceived by human ears
generally refers to the sound that frequency is in the frequency band of
20Hz-20KHz.
Ultrasonic
Generally refers to the frequency of more than 20kHz sound, the human ear
cannot perceive.
Sound image
It refers to the two-dimensional data table representing the intensity
distribution of sound sources in the space plane after the signal collected by
microphone array is calculated by the sound source location algorithm.
Palette
The color data used in the color mapping of an Sound cloud chart.
Sound cloud image
The sound pressure level data of each resolution point on the sound image
is mapped to a certain color number on the palette according to a certain
conversion formula to form a color image, and then it is fused with the visible
image to form an sound cloud image.

2
Test frequency range
When a frequency range is selected within the full frequency range
supported by the device, the device will only measure and display a sound
cloud image that is within this frequency range. Sound outside this frequency
range will not be displayed.
Frequency peak
A peak in spectrum，it denotes a strong sound energy distribution at this
particular frequency.
Dynamic range
The scale of the intensity of the sound source that can be shown on the
sound cloud image.
Field of view
For camera, it is an angle formed by camera and the two diagonal points of
the rectangular picture which is captured by the camera.
For sound cloud image,it is a angle formed by microphone array and the
two diagonal points of the rectangular sound image which is captured by the
microphone array.

Transient and steady state modes
Click the transient / steady state mode button to switch the working mode
of the equipment.
In the transient mode, the equipment has a very fast response speed to the
transient signal and can quickly respond to the change of sound source. It is
suitable for locating rapidly changing sound source models, such as partial
discharge sound source.
In the steady-state mode, the equipment will reduce the response speed
to the signal, and the cloud image will be relatively stable. It is suitable for the
observation of stable signals.
Video and photo
