Online salinity sensor
Measurement principle: To avoid electrode polarization, the sensor circuit generates a highly stable sine wave signal applied to the electrodes. The current flowing through the electrodes is proportional to the conductivity of the measured solution. The instrument converts the current into a voltage signal through a high-impedance operational amplifier, then after
After program-controlled signal amplification, phase-sensitive detection, and filtering, a potential signal reflecting conductivity is obtained; the microprocessor alternately samples the temperature signal and conductivity signal through switch switching, and after calculation and temperature compensation, obtains the conductivity of the measured solution at 25°C
value and the temperature value at that time.
Temperature compensation principle: The conductivity of electrolyte solutions is affected by temperature changes and requires temperature compensation. The temperature coefficient of weak aqueous solutions is 2.00%/°C; the higher the concentration, the smaller the temperature coefficient. For lower concentration (1µS·cm－1) solutions
The temperature coefficient does not use 2.00%/°C, but is set by the user, with a range of 0.00～9.99%.
