UV-SVP

Sound Velocity, Temperature and Pressure for Underwater Vehicles.

Designed for Underwater Vehicles where space is at a premium, the UV-SVP is based on the Valeport miniSVS. Incorporating Valeport’s class-leading time of flight sound speed sensor, a PRT temperature sensor and a 0.01% pressure sensor in a compact package weighing just 750 grams (in air), the lightweight titanium housing gives a depth rating of 3000m. A wide range (9-30V DC) isolated power supply and RS232 communications complete the package.

Technical Specifications

Sensors

Each sound velocity measurement is made using a single pulse of sound traveling over a known distance, so is independent of the inherent calculation errors present in all CTDs. Our unique digital signal processing technique virtually eliminates signal noise, and gives an almost instantaneous response; the digital measurement is also entirely linear, giving predictable performance under all conditions.
