uvSVX

uvSVX - Sound Velocity, Temperature and Pressure with calculated Salinity & Density for an Underwater Vehicle

Designed for underwater vehicles where space is at a premium, the compact uvSVX features Valeport’s Time of Flight technology that delivers SVP with calculated salinity and density data.

Accuracy

Interchangeable Pressure Sensors

High accuracy data is assured with the addition of Valeport’s uniquely interchangeable pressure module that allows users to maximise operationally specific depth requirements.

This advanced, calibrated pressure module, is quickly and easily changed whilst in the field, using the Valeport supplied adapter and without opening the instrument. Delivering accuracy to 0.01%, the interchangeable pressure transducer is available in 10, 20, 30, 50, 100, 200, 300, 400 and 600 Bar variants.

Using the latest developments in digital sensor technology the new uvSVX is lightweight, housed in titanium with a depth rating of 6000m and delivers reliable, accurate performance under all conditions.

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.
