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.
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.
1375 - 1900m/s
-5°C to +35°C
10, 30, 100, 300Bar
RS232 & RS485 output, selected by command code. RS232 data may be taken
directly into a PC over cables up to 200m long, whereas RS485 is suitable for longer
cables (up to 1000m) and allows for multiple addressed units on a single cable.
19200 - 115200
8 data bits, 1 stop bit, No parity, No flow control
8 – 30V DC Isolated
5 kg (in air)
Housing & Bulkhead:
· 0.5m interface cable
· Operation manual and transit case
XX denotes pressure transducer range.
Select from 10, 30, 50, 100, 300, or 600Bar
Some users need the superior Sound Velocity data from an SVP with the Salinity and Density data from a CTD. So Valeport has come up with the unique MIDAS SVX2 that combines both technologies to give the best of both worlds.
