The analog sensor for the EX measuring point come with open cable ends and can be connected to the respective monitor quickly and easily. There are monitors with one or two analog outputs available for both parameters. The monitor itself is connected to a isolated amplifier installed outside the EX area. Depending on the power supply and the data transfer, there are isolated amplifiers with 230 V or 24 V voltage supply or with HART® option available here.

You can install specific electrodes into the SensoLyt® 650-7 EX fitting, depending on the measuring and application range. The TetraCon® 700-… EX is a 4-electrode measuring cell with the highest linearity and insensitivity to contamination.
