Abstract

A simple salinity sensor for various concentrations of sodium chloride (NaCl) in de-ionized water is proposed and demonstrated. The beam-through technique is used to obtain output voltages of various sodium chloride solution concentrations. The concentrations of the sodium chloride solutions are measured in volume %. For a concentration change of sodium chloride from 0 to 12 % in de-ionized water, the output voltage increases linearly with a limit detection of 1.44 %. The fiber optic sensor is a promising alternative to other well-established methods for the measurement of sodium chloride solution concentration due to its simplicity of design, linearity, non-contact sensing, ruggedness and low fabrication cost.
