Hello guys
Iam working in Washing plant sure washing water PH is very important to us we use only one dosing pump for SODA we change the dosing manually "L/H" we have no any automatic control for PH only by lab test we increase or decrease the dosing
I want to control it by the same way but using PH sensor and dosing pump which I can change the dosing automatically so I searched in this forum and after that I decided to use FU20 pH/ORP Combined Sensor from yokogawa where I want the sensor to measure PH from 2 to 12 and give me a signal 4-20mA I will use in PLC program then change the dosing this process will repeated every 5 mins
my questions
1- is my choice the best or there is a better sensor?
2- I know PH process is not linear so Is my process good or not?
3- from the attached Pics I can not know the terminal of PH signal?
I appreciate your help
