Overview
CRY2620 is the 64-MIC version hand-held industrial acoustic imager, support
the 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.
CRY2620 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, 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
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
