Multi-functional acoustic imager, using imported high-sensitivity digital microphone, is mainly used to detect gas leakage under pressure and partial discharge of electrical insulation equipment, and can also expand functional detection, including infrared thermal imaging detection, internal leakage detection or other detection functions.
It is designed with a fill light for detecting low light environment and has the function of external sensor. The fuselage adopts aluminum alloy shell to increase the durability of the equipment, and the explosion-proof needs are considered in the structure and circuit design, so some models can be used in explosion-proof environment.
In this chapter, we will introduce the adjustment and function of decibel threshold.
Decibel threshold:
The decibel threshold is a specific measure of sound intensity, in decibels (dB). When the sound intensity in the environment reaches or exceeds this set decibel threshold, the microphone array of the device will capture the sound. Its function is to make the equipment respond to the sound with a certain intensity level, and to ensure that the more prominent sound signals are given priority among many sounds, so as to improve the detection and processing efficiency of the equipment for specific sounds.
The above is about the customization and adjustment of decibel threshold. If you have any questions about the use of acoustic imager, please call for advice.
