CTDs for gliders and AUVs: low power, high accuracy
Power efficient, high accuracy, easy to integrate
Our RBRlegato⁴ and RBRcentauro³ CTDs offer a new world of measurement opportunities for gliders and AUVs, power efficient and optimized for flow dynamics with no pump required for fine structure measurements.
Available on gliders and AUVs from leading manufacturers
Designed to integrate simply on any vehicle, the RBRlegato⁴ and RBRcentauro³ CTDs draw 90% less power than comparable instruments — a result of modern electronics and no moving parts. Both instruments can also expand their sensing capability by connecting and controlling additional sensors, including the RBRcoda³ T.ODO, RBRtridente, and RBRquadrante.
