Abstract

The invention discloses a digital on-line water quality analysis sensor which comprises a shell, a water quality analysis electrode and a signal processing module, wherein the water quality analysis electrode is arranged at the top end of the shell; the signal processing module is arranged in the shell, is connected with the water quality analysis electrode through a signal output wire and is used for converting a signal acquired by the water quality analysis electrode into a digital signal and then outputting the digital signal. An original analog signal of the sensor is converted into a standard digital signal, so that the standard digital signal is difficultly interfered by the outside when being sent to an instrument; a remote sending distance is longer than 200 meters; the digital on-line water quality analysis sensor is suitable for a use environment having a special requirement on mounting; mistake signals generated by outside interference are actively filtered out through a program in a signal conversion module, so that measurement mistakes are avoided.

Description

technical field [0001] The invention relates to a water quality analysis sensor, more precisely a digital online water quality analysis sensor. Background technique [0002] The online water quality analyzer sensor is used for the original signal detection of water quality indicators, including pH value of water quality, oxidation reduction potential value ORP, conductivity, dissolved oxygen, residual chlorine, turbidity, ion concentration, suspended solids concentration, etc. The current sensors directly sense and output the original signal through physical or chemical methods. In practical application, there are several problems: first, the signal transmission process is easily disturbed; second, the signal transmission distance generally cannot exceed 30 meters; The third is that the wrong signal cannot be filtered out automatically. Contents of the invention [0003] Due to the above-mentioned shortcomings of the prior art, the present invention proposes a digital onl...
