0.0~200.0mS/Cm RS485 Conductivity Electrode For Waste Water Online Detecting
Conductivity sensor technology is a very important field of engineering technology research. It is used to measure the conductivity of liquids and is widely used in human production and life. An indispensable detection and monitoring device in production and technology development. The conductivity sensor mainly measures and detects industrial production water, human domestic water, seawater characteristics, electrolyte properties in batteries, etc.
Conductivity sensors can be divided into electrode-type conductivity sensors, inductive-type conductivity sensors, and ultrasonic conductivity sensors according to different measurement principles and methods. The electrode type conductivity sensor adopts the resistance measurement method according to the principle of electrolytic conduction.
To measure the conductivity, the conductivity measurement electrode is a complex electrochemical system in the measurement process; the inductive conductivity sensor realizes the measurement of the conductivity of the liquid according to the principle of electromagnetic induction; the ultrasonic conductivity sensor changes in the liquid according to the ultrasonic wave To measure the conductivity, the first two kinds of sensors are the most widely used.
