Valeport Ltd

Sound velocity sensors

Valeport is the world’s leader in providing Sound Velocity technology. Valeport’s MiniSVS Sound Velocity Sensors range offers pioneering digital time of flight technology with advanced material composites that results best in sound velocity accuracy.

Sonar, single beams, multi-beams, underwater positioning systems – they all use acoustic signals, and rely on accurate knowledge of the speed of sound for optimal performance. Our unique digital signal processing technique virtually eliminates signal noise, and gives almost instantaneous response; the digital measurement is also entirely linear, giving predictable performance under all conditions. A wide range of 1375 – 1900 m/sec with an accuracy of +/-0.002 m/sec and resolution of 0.001 m/sec can be sampled at a rate up to 60Hz. Units are available in a variety of titanium and acetal housed options with OEM versions to customer configurations.

Specifications:
 

• Genuine Accuracy of ±0.02m/s (Total Error Budget)
• Precision (peak to peak noise) of ±0.002m/s
• Operating range of 1375m/s to 1900m/s (covering all environments from fresh water to the Dead Sea and the Marianas Trench)
• Data rates up to 60Hz (instrument dependent)

As well as having a range of standard products, Valeport is able to offer customized solutions.
