I am developing a monitoring system for a plating line. I have pH sensors going into a fieldpoint analog input module. I get a reading in volts but I am not sure how to transfer that into an actual pH reading. What do you think? Thanks for your help, john
Once you get your voltage reading you can convert that reading into pH with some math or using a formula node. For example, I have seen that the specs for pH sensors will have an output parameter of XX.X mV/pH so you could simply divide your voltage (in mV) by XX.X which will give you pH.
