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.
Fitted with Valeport’s digital sound velocity sensor, high stability conductivity sensor, high accuracy temperature compensated piezo-resistive pressure transducer, and fast response PRT temperature sensor.
Using the concept of distributed processing each sensor has its own microprocessor controlling sampling and calibration. Each is controlled by a central processor that issues global commands and handles all data. Consequently all data is sampled at precisely the same instant, giving superior quality profile data.
System is supplied with DataLog X2 Windows based PC software, for instrument setup, data extraction and display. DataLog X2 is licence free.
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:
2 wire power and comms up to 6000m of cable (cable dependent)
Fitted with 16Mb solid state non-volatile FLASH memory. Total capacity depends on sampling mode; continuous & burst modes have a single time stamp at the start of the file, trip mode (profiling) stores a time stamp with each reading.
