Unlocking Precision: The Power of the UL-CTD Sensor

Introducing the UL-CTD: A Breakthrough in Low-Power Sensing Technology

The UL-CTD stands out in the market for itS exceptional accuracy and depth capabilities, paralleling the performance of D-2’s hybrid CTD while consuming only 50 mW of power. This makes it one of the most energy-efficient closed-field CTDs currently available. By integrating both electrode and inductive sensing methods, this sensor boasts a compact design and enhanced precision, allowing for free-flushing without the need for a pump in most scenarios.

Unmatched Features for Deepwater Applications

the UL-CTD is equipped with an extensive array of features that surpass any other deepwater CTD sensing solution on the market. Users can select sample rates of either 1 Hz or 2 Hz, and it supports the integration of various third-party sensors thru A/D and serial interfaces. Data transmission options include USB, RS-232, and RS-485, as well as wire line dialog using widely available telemetry systems.

Durable Design for Diverse Environments

With options for aluminum, stainless steel, or titanium housings, the UL-CTD is designed to meet various depth and environmental challenges. Its compact dimensions and low power requirements make it especially suitable for SWaP-constrained systems, including small Unmanned Underwater Vehicles (UUVs), ocean gliders, and USV-towed arrays.
