Ohmex

Knudsen

Knudsen Engineering Limited (KEL) building echosounders for most of its existence. Starting in the late 1980’s with the 320A, designed for helicopter surveys in the high Arctic, and continuing with the 320M, 320B and their derivatives, Knudsen echosounders are now used in more than 60 countries around the world. Known for their pioneering use of digital signal processing (DSP) technology, Knudsen sounders are used in a wide range of applications, from shallow-water hydrographic survey to full-ocean depth scientific research.

Knudsen Products:

Knudsen 320 series echosounders

These are currently used worldwide for precision measurement of water depths for a variety of applications, ranging from hydrographic surveys to oceanographic research. The original 320M Echosounder, a well known and respected workhorse of the survey world has recently been updated and replaced with 2 new models to better meet today’s technology requirements and take our customers into the next generation of survey needs.

Sounder and Chirp Echosounders

Knudsen latest developments are the new Sounder and Chirp series echosounders. These two new series are KEL’s first completely new design since the introduction of the successful 320 Series and represent a great leap forward in echosounder design. Based on the latest generation of 16-bit Digital Signal Processors from industry leader Texas Instruments, the Sounder and Chirp will become the new benchmark for performance and accuracy.

Digital signal processing is key to the performance of the new systems. The Sounder and Chirp systems digitize the entire incoming signal over an exceptionally wide bandwidth of 230 kHz, and extract the frequency of interest entirely with digital signal processing software. The digital filters implemented in the Sounder and Chirp systems provide stability and selectivity simply not achievable with analog components, and the TI DSP has the processing power to recover the signal from even the noisiest environments.

Sounder Series

The Sounder Series offers a variety of frequency agile echosounders for shallow water to mid ocean depth hydrographic surveys.
