About Salinity Sensor:
DEC-221 is an electrodeless induction-based salinity sensor that uses a generator to generate an alternating magnetic field in the primary coil to generate an inductive current in the medium. The intensity of the inductive current depends on the ion concentration in the medium. The inductive current generates another magnetic field in the secondary coil. The receiver measures the inductive current on the coil to determine the salinity of the medium.
Features:
1. Digital sensor, direct output of Rs-485 digital signal, support MODBUS/RTU
2. Built-in temperature sensor for automatic temperature compensation
3. No electrode, therefore no polarization reaction
4. Measurement and media are completely electrically isolated, can be used for high-precision measurement of heavy and easy to precipitate media or solution, low maintenance costs
5. Low sensor power consumption, internal circuit anti-interference design
Scope of application:
Ocean, industrial wastewater, pharmaceutical, biotechnology, industrial manufacturing and other online whole process monitoring.
