- AS118 Sensor
The AS118 sensor is suitable for measuring sulfuric acid in the concentration range of 0% to 5% and 96% to 100%, and can also measure the concentration of lye and saline solutions up to 500 to 2,000,000uS/cm, especially suitable for the concentration of concentrated sulfuric acid in high temperature environments and easily crystallized clog solutions. The sensor is designed based on the principle of electromagnetic induction and consists of a pair of electromagnetic coils. During the measurement process, complete isolation is achieved between the induction element and the measured medium. Of this pair of coils, one acts as the transmitter and the other as the receiver. When the coil is energized, the conductivity of the electrolyte solution generates an induced current, and the strength of this current is proportional to the conductivity of sulfuric acid. The receiver coil then detects the magnitude of this current and calculates the conductivity value of the sulfuric acid.
