D-2's Hybrid CTD sensor utilizes a novel conductivity measurement approach that combines the advantages of electrode and inductive sensing techniques, offering excellent accuracy and precision at depths of down to 11,000 meters. In addition, it incorporates a high-resolution strain-gauge pressure sensor, cutting-edge solid state electronics and signal processing, and a choice of industry-standard or best-in-class temperature sensors.
The sensor's proprietary technology enables a more compact and lightweight design that makes it ideal for AUVs and underwater robotic vehicles, and also allows the sensor to be free-flushed with no pump required for the majority of applications.
The Hybrid CTD offers a rich suite of features that is unmatched by any other deepwater CTD sensing solution on the market. High-speed sampling capabilities enable the user to select rates of up to 25 Hz, and additional third-party sensors can be connected via A/D and serial interfaces. Data can be output via USB, RS-232 or RS-485, and can also be transmitted via a wire line using commercially available telemetry systems.
The rugged sensor can be provided in aluminum, stainless steel or titanium housings to meet different depth and environmental requirements. Specialized custom and OEM variants are also available, allowing you to tailor a bespoke solution to your specific underwater vehicle.
