China Deep Sea Echosounder

The HY1690 is a digital echosounder ideally suited for offshore survey in deep water down to 10000 meters water depth. It is composed of a mainframe and two transducers of which frequency is 10.5 kHz and 25 kHz respectively. The mainframe, consisting of an industrial control computer system and two transceivers which work standby for each other, is responsible for the data acquisition and processing. The HY1690 realizes the intelligentized operation and control by adopting the technology of digital signal processing (DSP) and computer graphics display.
