Product Description

The development of Valeport Mini SVP sound velocity meter aims to provide a cost-effective tool for collecting sound velocity information without affecting the quality of the data. MiniSVP is an ideal choice for ROV, coastal or small boat applications, particularly suitable for survey companies, military and academic communities, and similar institutions. It is simple to use and easy to handle.

sensor

The miniSVP is equipped with Valeport's digital time-of-flight sound velocity sensor, PRT temperature sensor, and strain sensor

Pressure sensor.

sound velocity

Range: 1375 to 1900m/s

resolving power: 0.001m/s

Accuracy: ±0.02m/s

temperature

Scope:- 5 ° C to+35 ° C

resolving power: 0.001°C

data acquisition

MiniSVP has multiple pre programmed sampling modes, covering many standard applications. Can operate between 1 and 16Hz

Sampling data within a certain range to make it suitable for rapid analysis or continuous measurement at a fixed point

Sampling mode

Continuous: All sensors output periodically at 1, 2, 4, 8, or 16Hz.

Analysis: Specify the amount of water column to record data when the device descends (or rises)

signal communication

The instrument will operate autonomously and communicate directly with a personal computer for setup and data extraction before and after deployment. It can also perform real-time operations, with optional communication protocols as standard configuration, and pin selection on the output connector:

RS232: Cable up to 200 meters long, directly connected to the serial port

RS485: Cable with a maximum length of 1000 meters

Baud rate: 4800 – 460800

Protocol: 8-bit data bit, 1-bit stop bit, no checksum, no flow control

Bluetooth: Bluetooth recorder and communication set for cable free data recovery (500 meter rated) memory

The miniSVP is equipped with a solid-state non-volatile FLASH memory that can store over 10 million rows of data (equivalent to 10000 analytical data to a resolution of 500-1 meters).
