Right. In attachment the datasheet of the cell. We have other options but this is apparently more adequate for our application. AttachmentEMEC-ECDI-Probes-PVDF-body-SS-Electrodes-Data-Sheet-R1-07-10.pdf (247 Downloads) |

I found transmitters that emit a 4-20mA signal but that significantly alters the costs. Another option I found via aliexpress but these Chinese products do not bring me any solid documentation, dubious quality and no guarantees. This weekend I sent e-mails to companies that work with isolating amplifiers, I will probably only receive a reply next week. With these modules I intend to convert the electrical resistance of the cells to a 4-20mA signal. One other way is to use a Burket cell (no cheap but could be one alternative) there more inforamtion on the datasheet. Could tell if there solutions for LOGO using this cell model?

Hello, I found a conductivity cell that is compatible with our idea, it seems to me that there is no LOGO module that converts the electrical resistance of the cell into a 4-20mA or 0-5V signal. However, I would like to know if for Siemens there would be any other PLC model that could have a module that would make this conversion. Could you tell me?
