| Abstract: | The working principles and internal structure of a residual chlorine sensor and residual chlorine online measurement system have been investigated, and the design of the hardware circuits, the polarization voltage circuit, the signal transduction of weak current to voltage signals, the secondary signal amplifier, and the data processing circuit are described in detail. Experiments with zero residual chlorine values and comparison with a commercial PLC 3200 chlorine analyzer were used to determine the calibration curve and confirm the reliability and stability of the system, which can be used for the detection of residual chlorine in daily domestic water. |
