Valeport miniSVS: Sound Velocity Sensor

Availability: , ,

The Valeport miniSVS uses 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.


Each sound velocity measurement is made using a single pulse of sound travelling over a known distance, so is independent of the inherent calculation errors present in all CTDs.

The unique digital signal processing technique virtually eliminates signal noise, and gives almost instantaneous response.

There is a choice of data formats to allow an interface to pre-existing systems.


Sound velocity range: 1375 – 1900 m/s

Sound velocity resolution: 0.001 m/s

Baud Rate: 2400 – 115200 (NB. Low baud rates may limit data rate)

Data output protocol: 8 data bits, 1 stop bit, No parity, No flow control

Voltage: 8 – 30 V DC
