Salinity sensor

Automatic temperature compensationNonpolarizing reaction
The salinity sensor based on electrodeless inductive measurement uses a generator to generate an alternating magnetic field in the primary coil, and an induced current is generated in the medium. The intensity of the induced current depends on the ion concentration in the medium.
The induced current generates another magnetic field in the secondary coil.
The receiver measures the induced current on the coil, thereby determining the salinity of the medium.
At the same time, the built-in temperature sensor can automatically compensate the temperature, which is suitable for online long-term monitoring environment.
