First of all, sorry for my English and I am a starter in LOGO as well. How I going to trigger the alarm in LOGO when the pH sensors have detect the pH value of chemicals which is less than 11.1 and more than 11.4? The sequence of operation is when the chemical is in normal pH (between 11.1 till 11.4) then the sequence will go on normally. But without the range, it needs to send the signal to PLC thus the alarm will trigger. I have used the LOGO! AM2 expansion module to monitor the pH value. While the range of the sensors can be detected is 0-14. The output for the sensors wanna make it in 4-20mA. Besides I have no idea how to set the gain and offset for it. Any help would be appreciated. Thanks. AttachmentGF pH sensor.pdf (158 Downloads) |
