Valeport Releases White Paper on Midas SVX2

Valeport, manufacturer of hydrographic and oceanographic instruments, has released a white paper on the Midas SVX2.

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.

The Midas SVX2 is fitted with Valeport’s digital time of flight sound velocity sensor, high stability conductivity sensor, a high accuracy temperature compensated piezo-resistive pressure transducer, and a fast response PRT temperature sensor.

The instrument will operate autonomously, with setup and data extraction performed by direct communications with PC before and after deployment. It also operates in real time, with a choice of communication protocols for a variety of cable lengths, all fitted as standard and selected by pin choice on the output connector.

The Midas SVX2 is also fitted with 16Mb solid state non-volatile flash memory. Total capacity depends on sampling mode. Continuous and burst modes have a single time stamp at the start of the file, trip mode (profiling) stores a time stamp with each reading. A single line of SVP data uses 10 bytes, and a time stamp uses 7 bytes.
