Aanderaa’s roots were formed in the need to make reliable measurements in the earth’s most harsh environments. Founded in the early 1960s by Ivar Aanderaa, the Aanderaa name quickly became synonymous for robust and reliable instrument solutions for oceanographic and other environmental measurements. Now as part of Xylem, Inc., the Aanderaa reputation continues to serve the global need to have better, smarter, and more robust sensor and systems solutions. Aanderaa actively collaborates with other companies within the Xylem Analytic family giving it a global access to its customer base and systems integration capabilities in remote parts of the world.
Aanderaas’ latest innovative environmental  products such as the new in-line ZPulse DCS for easy system integration, the Doppler Current Profiler Sensor Sensor as a stand-alone product as well as the SeaGuardII DCP with Dual Head , marks a turning point in distributed instrumentation for underwater measurements of Hydro Acoustic, Electro-Optical, Electro-Chemical, Pressure, Temperature, Meteorological data in observing networks and self-contained instrumentation. At the core of the system is the CANBus based AiCaP protocol, which enables self-detection of connected sensors and dynamic setup of configuration menus. This protocol was developed by Aanderaa in order to achieve the extreme low power requirements of the Underwater Observatories. The master-slave protocol extends the CANBus protocol with extra signaling to efficiently wake up sensors or datalogger to receive data when necessary. Sensors on the bus perform their own measurements at the required intervals and send collected data to the SeaGuard or SmartGuard logger. These dataloggers assemble the datasets and package them to ensure safe communication of data to a receiving station utilizing the Real-Time communication system. Sensors on the AiCaP bus are utilizing Smart Sensor technology and can operate both in the bus configuration and as stand-alone entities. In the latter mode, they can be interfaced to any computer or logger using the RS-232 port and can be programmed to varied modes of operation.
