Replacing Valeport’s renowned Model 650 Mk2 Sound Velocity Profiler, it features titanium construction and a large memory. As well as using the world leading digital time of flight sound speed sensor, the instrument has a ±0.01% pressure sensor, and features Valeport’s synchronised sampling technique to guarantee that all sensors are sampled at exactly the same point during a profile.
The MIDAS SVP is fitted with Valeport’s digital time of flight sound velocity
sensor, a high accuracy temperature compensated piezo-resistive pressure
transducer, and a fast response PRT temperature sensor.
The MIDAS SVP uses the concept of distributed processing, where each sensor
has its own microprocessor controlling sampling and calibration of readings.
Each of these is then controlled by a central processor, which issues global
commands and handles all the data. This means that all data is sampled at
precisely the same instant, giving superior quality profile data.
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 & comms up to 6000m of cable (cable dependant)
The MIDAS SVP is 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. A single line of SVP data uses 8 bytes, and a time stamp
uses 7 bytes.
System is supplied with DataLog Express Windows based PC software, for
instrument setup, data extraction and display. DataLog Express is license free.
Designed for coastal, harbour and inland hydrographic survey use, the SWiFT SVP makes a seamless workflow a reality in a compact, robust and portable package.
Rapid collection of sound velocity profiles with no compromise in the quality of the data is the rapidPro SVT’s great party trick.
