The profiler has a built-in flash memory with the ability to store more than 10 million data lines (the equivalent is 10,000 profiles per 500 m, with a profile resolution of 1 m). The kit includes Windows-based software DataLog Express. The collected data is transferred to a personal computer using an RS 232 cable after the profiler has been lifted from the water. The profiler works autonomously (from the battery). In this case, the data recording takes place practically at each point, which, in the aggregate, forms the so-called sound velocity profile (sound velocity values during descent / ascent). ▪ Profile: Recording data at a specified frequency while plunging / lifting the device throughout the water column. ▪Ĝontinuous: Recording data at a frequency of 1, 2, 4, or 8 Hz The miniSVP prophyler is equipped with three sensors: a sound velocity sensor in water, a temperature sensor and a pressure sensor.el, to which is also fastened the rope cable necessary to lower the profiler into the water. To avoid damage during deployment, the device is placed in a protective mesh container made of stainless ste The profiler is convenient and easy to use and is considered one of the most accurate and reliable sound speed profilers in the world. Sound velocity profiler "miniSVP" suits for operation both on remotely operated underwater vehicles (ROV), and on launches or boats. company, UK) are uses by specialists of SE PMGE for determination the exact value of sound velocity. Sound velocity profiler “miniSVP” (produced by Valeport Ltd. The device can be powered from both internal and external sources.ġ00, 400, 1000 и 3000 nephelometric turbidity unitĠ,01, 0,01, 0,1 and 0,1 nephelometric turbidity unit
Upon registration with a time interval of 25 seconds or more, the device is turned off in the interval between sampling to conserve battery power.ĭata exchange with the device is performed using RS-232 or RS-485 connectors. The sampling rate is programmed by time (25 Hz for every 24 hours), by pressure (0.1 bar or more) or by the velocity of sound (0.1 m / s or more). The actual service life varies depending on the installed sensors. X" is able to register continuously for 2 days with fresh alkaline batteries.Additional ports of the Xchange sensor, up to five digital ports or up to 10 analog ports, can be added by the manufacturer on demand. X" device has one main port of the Xchange ™ sensor (conductivity or sound velocity), as well as two auxiliary ports of the Xchange ™ sensor (temperature and pressure).It is mainly designed to produce profiles at great depths using a winch. X" is a data recording device with several sensors of the X-series family.X" of the company "AML Oceanographic" (Canada).In its work, SV PMGE uses the sound velocity profiler "Plus
