Stand-Alone Doppler Current Profiler Sensor
The Aanderaa Current Sensors are available in a profiling and a single-point version with three depth ratings. We offer Doppler Current Profiler Sensor, Doppler Current Sensor and the In-line ZPulse Doppler Current Sensor.
The Doppler Current Profiler Sensor (DCPS) is a medium-range, 600kHz current profiler smart sensor. It offers high-quality ocean current measurements and is ideally suited for cabling directly to various systems or dataloggers via serial or AiCap bus. With its integrated compensation for tilting and movement, the sensor is commonly used to measure current from buoys and other moving platforms.
The 5400/5400R version of the current sensor is 300m depth rated, the 5402/5402R version is 4500m depth rated, and the 5403/5403R version is 6000m depth rated and intended for commercial as well as research use. It comes with an integrated temperature sensor that can be calibrated on request.
As an extension to the DCPS, we now offer the current profiler with an integrated pressure unit called the 5400P. This version enables acoustic wave measurements in addition to profiling currents. Ideal for small observatories, the DCPS sensor is the market's lowest-cost current and wave sensor.
The Aanderaa Doppler Current Sensor is a rugged, true vector averaging current sensor for measuring current speed and direction in the sea. The sensor has built-in compass and tilt sensor and may also output sea temperature. The speed range is 0 to 300 cm/s. Low current drain and flexible sampling schemes. New multi-frequency (DCS) with ZPulse technology achieves better performance using only half the power than previous models. The new, fast response compass and tilt circuitry has no moving parts achieving excellent performance in unstable areas such as in the wave zone close to surface.
The inline ZPulse Doppler Current Sensor has been designed in order to easily integrate into systems offering a compact and elegant solution. The ZPulse sensor is based on a modified version of the ZPulse DCS 4520. The unit connects to a combined mooring and signal cable in one end and allow for connection of a continuation cable at the opposite end. The inline ZPulse current sensor can hold a load of up to 1300 kg. It has been developed to replace the previous Aanderaa DCS 4100 using newer technology and extending capabilities.
