Ozone concentration detector.It is able to ensure that the pure water ozone produced by so designing the monitoring point obtained
Concentration value meets requirement.
As preferably, described monitoring point is provided with sampling valve and probe tube, wherein samples the size of valve
With the consistent size of probe tube, sampling valve is connected with ozone concentration detector by probe tube, and logical
During the sampling of over sampling pipe, slowly open sampling valve.Sampling valve and the size design of probe tube so that ozone
The detection of concentration value is the most accurate, and the opening ways sampling valve makes the ozone concentration value that detects more
Precisely.
As preferably, in step (2), ozone concentration detector by the ozone concentration value that detects with electricity
The form of stream signal is transferred to PLC, PLC by calculating actually detected numerical value.Pass through current signal
Design make to transmit safer reliably.
As preferably, in step (3), by the actually detected numerical value in step (2) and PLC
Setting value compares, and calculates a current signal by PID controller.Pass through current signal
Design make to transmit safer reliably.
As preferably, in step (4), step (3) will calculate gained current signal transfer to smelly
Power regulation circuit plate on Oxygen Generator, power regulation circuit buttress is sent out to regulate ozone according to the current signal accepted
The Power Regulation power of raw device, thus regulate the ozone concentration value of ozonator output.By power regulation circuit plate
Adjust Power Regulation power to facilitate the control of ozonator, easy to operate.
The invention has the beneficial effects as follows: can real-time monitoring ozone concentration automatically, reduce working strength,
Improve work efficiency, effectively reduce production cost, easy to operate, detection is precisely, safe and reliable.
