The UL-CTD provides the same market-leading precision and depth performance as D-2's Hybrid CTD but with a power draw of just 50 mW, making it one of the lowest-power closed-field CTDs available. Combining the advantages of both electrode and inductive sensing techniques, the sensor features a smaller footprint and improved precision, and can be free-flushed with no pump required for the majority of applications.
The UL-CTD offers a rich suite of features that is unmatched by any other deepwater CTD sensing solution on the market. It features user-selectable sample rates of either 1 or 2 Hz, and a variety of third-party sensors can be integrated 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.
Available with aluminum, stainless steel or titanium housings to suit different depth and environmental requirements, the sensor's compact size and low power consumption make it ideal for SWaP-limited systems such as small UUVs, ocean gliders and USV-towed arrays.
