Tetrapulse is the world’s most compact subsea electric sensor, and is based on ELWAVE’s proprietary CEDAR technology, which draws inspiration from the electrical sensory perception of tropical freshwater fishes. Utilizing an array of up to four electrodes, the modular system can be provided with cables ranging from 1.5 to 7 metres in length, and is ideal for a wide range of underwater vehicles and platforms as well as fixed-site installation.
The sensor provides highly effective detection, localisation and classification of metallic and non-metallic objects and surfaces, as well as buried objects at depths of 1 to 2 metres. Rated for depths of down to 300 metres, it provides robust performance in water or in air, and in highly noisy environments.
The export restriction-free Tetrapulse is provided as a complete kit comprising the sensor pod, up to four electrodes and cables, and all necessary firmware and user interface software.
