Overview
CRY2624 is the ATEX version anti-explosion hand-held industrial acoustic
imager, support the ultrasonic frequencies, with II 3G Ex ic IIC T5 Gc
explosion-proof grade. 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.
CRY2624 industrial acoustic Imager helps you quickly detect potential
pressurized gas leakage and vacuum leakage 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 ranges 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, it 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 a 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

User Manual V1.2
M e a s u r e B e t t e r S o u n d

conversion formula to form a color image, and then it is fused with the visible
image to form a sound cloud image.
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 an 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.
