Aanderaa SeaGuard IIDCP Doppler current profiler

Seaguard II DCP is a brand new series of acoustic velocity profiling instruments in the Ocean Guard series. It greatly improves the acoustic profiling capability and further enhances the ability of the anchor system to collect high-quality ocean current data when moving or tilting.

It can be used for both self-contained measurement and real-time online monitoring, meeting different measurement needs of users. SeaGuard II is an intelligent data acquisition and control center, which is composed of SeaGuard electronic components and Andra's advanced management software SmartGuard.

The working frequency of Seaguard II DCP is 600kHz, and the equipment can measure ocean currents while also measuring multiple parameters of water quality. In order to meet the special requirements of monitoring the upper ocean environment, many innovations have been made in product design, such as extending the deployment time and optimizing the flexibility of configuration.

This device can be equipped with multiple different Aanderaa smart sensors, such as temperature, pressure, conductivity, dissolved oxygen, waves, tides, and turbidity. The Seaguard II has four analog interfaces and two serial interfaces for external power supply and real-time data transmission.
