CHAPTER 1 Short Description and Specifications
The Oxygen Optode is an optical sensor that does not consume oxygen. The measurement principle is
based on fluorescence quenching see appendix 1, while traditional polorographic oxygen sensors, often
called Clark sensors, based on electrochemical principles consume oxygen.
The optical oxygen sensors described herein belong to the Aanderaa series of smart multi-parameter
sensors.
Apart from a high quality temperature channel which is almost always included for automatic
compensation in all of Aanderaa's series of smart sensors; Aanderaa produces other smart sensors to
measure water Currents, Conductivity, Wave/Tide and Pressure.
Features common to these sensors include:
•
Internal Digital Signal Processor (DSP) to optimise data acquisition and improve accuracy,
resolution and stability
•
Multi-parameter outputs measured/calculated/presented within the sensor e.g. for oxygen O
µM, O
in % saturation, Temperature and Raw data
2
•
Calibration coefficients stored in sensor and unique sensor identification number
•
Autonomous sampling, 1 second to 4 hour sampling interval
•
AiCaP (CAN bus) communication which means that up to 20-25 sensors can be "plug and play"
connected to Aanderaa SEAGUARD
and recognizes the sensor.
•
RS232 serial communication so that these sensors can be connected directly to computers or
third party platforms e.g. data loggers from other manufacturers, gliders, floats, buoys, landers,
cable operated and autonomous vehicles,
•
Optional Analog 0-5 V, 4-20 mA adaptors available for 4330 and 4835
.
