Fiber optic salinity sensor: temperature influence on salinity measurement

The temperature influence on salinity measurement by optical fiber salinity sensor has been investigated. Study of the sensor sensitivity with temperature change in range of temperatures 20 - 80 degree(s)C is presented. The construction of the sensor has followed the example of differential refractometer. As a result of this construction and high sensitivity of sensor on salinity, temperature changes have not deformed salinity measurements with the use of this sensor.
