Digital Echo Sounder

Listing ID #3606683

A Low cost portable echo sounder integrated with a GPS and a telemetry system was designed, developed and tested up to 80 m water depth off-chennai with endogenously made transducer.GPS interface and RF telemetry were provided in the echo sounder to enable the user to note the position of the vessel and water depth at any location in the boat and is given in above figure. The remote hand held display for the echo sounder makes it convenient for the fishing trawlers and small boats to see the depth and location of the boat during their voyage.Very few electronic components are directly exposed to the hydrostatic pressure exerted by the water column above them. Most of the components and PCBs are housed in either in pressure casing, which can withstand the pressure or in a pressure compensated chamber.
