Sound Veloocity Sensors and Profilers

Sound Velocity Sensors & Profilers

 

Sound Velocity Sensors and Profilers from Valeport, the world leaders in Sound Velocity technology – a position achieved by both innovative development and meticulous attention to detail throughout the design, manufacture and especially calibration processes. Having been established at the forefront of this field nearly a decade ago with Digital Time of Flight technology, Valeport have now made a series of incremental changes to reinforce that position, ensuring that Valeport SV sensors offer levels of performance that are demonstrably far in excess of even the latest offerings from our competitors.

  • 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, we are also able to offer customised solutions, thanks to our in-house design and manufacture capability.

UV-SVP
Based on the Valeport miniSVS, the UV-SVP offers a form-factor designed for Underwater Vehicles where space is at a premium. 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.

MIDAS SVX2 Combined CTD/SVP
The MIDAS SVX2 is the latest version of Valeport's unique instrument. Recognising the conflict faced by users requiring the superior Sound Velocity data from an SVP, but still needing the Salinity and Density data from a CTD, the MIDAS SVX2 combines both technologies to give the best of both worlds. Now fitted with a 0.01% pressure sensor as standard, the SVX2 also uses synchronised sampling to ensure perfect profiles, and since the digital time of flight SV sensor is the most accurate in the world, it's also possible to compare the true sound velocity data with that generated by commonly used equations.

MiniSVS Sound Velocity Sensors
The miniSVS Sound Velocity Sensors use state of the art digital "time of flight" technology to provide the lowest noise, highest accuracy, best resolution sound velocity data available. Small size and a choice of sensor lengths down to just 25mm make the sensor suitable for a variety of applications, and the optional pressure or temperature sensor adds versatility. There is a choice of data formats to allow interface to existing systems. We will also consider OEM and custom designs. More Info

Soundbar 2 Digital Bar Checker
The SoundBar 2 Digital Bar Checker offers a convenient, quick and safe method of obtaining sound velocity data for calibration of echosounders and other acoustic devices. Developed from the acclaimed miniSVS sound velocity sensor, the SoundBar 2 uses a digital time of flight technique that gives the most accurate sound velcoity data in the world. Coupled to a pressure sensor in a durable titanium housing, the SoundBar 2 is lowered through the water column, measuring the sound velocity as it goes. The display unit records this data and presents the mean sound velocity value over the profile, which may then be output in a variety of industry standard formats to the echosounder. More Info

OEM SV
Valeport “Time of Flight” sound velocity technology is available in a number of standard instrument packages, which we believe cater for the majority of applications requiring the ultimate in SV measurement. However, our in-house design and manufacture capability means that we are able to provide customized versions of this technology to suit less mainstream or emerging applications, or for integration into third party systems. Please contact us to discuss your requirements. More Info

Thru-Hull SVS
A specific configuration of Valeport’s MODUS SVS sound velocity sensor, allowing the probe to be deployed through the vessel’s hull and safely recovered for cleaning and maintenance without requiring docking. It is particularly useful for multibeam applications where knowledge of the sound velocity adjacent to the multibeam transducer is necessary. The probe is also available with an optional PRT temperature sensor. More Info
