Logger version 2-D electro-magnetic current meter for deep ocean

INFINITY-Deep AEMD-USB - JFE Advantech Co., Ltd.

INFINITY-Deep is an autonomously deployable data logger for current speed measurements in the deep oceans. The currents in the deep oceans are very weak. It is too hard to accurately measure the deep water currents by some ADVs (Acoustic Doppler Velocimeters) that detect the Doppler-effect by scatter with the suspended particles in the water, because the concentration is very low. INFINITY-Deep measures 2-D current data through a magnetic field according to Faraday's law. Therefore, even if the suspended particles do not exist around the sensor, it can provide the accurate current data. The depth rating is 6,000m. Compared to INFINITY-EM, the instrument has a depth and a tilt sensors to monitor mooring status. Also, the battery capacity doubles for long-term current velocity measurements.
