DULCOMETER® Signal Converters 4 - 20 mA


DULCOMETER® Signal Converters are compact 2-wire measurement transmitters used for operation with pH, Redox, Temperature and Fluoride sensors. They can easily be connected to programmable logic controllers via a 2-wire connection. DULCOMETER® measurement and control devices grant highest process safety in a comprehensive application spectrum.

Advantages

  • Safe transmission, even over long distances
  • Disturbance free standard 4...20 mA signal
  • Easy installation directly on the respective sensor

Application Areas

Reliable long distance transmission of sensitive measurement parameters (e.g. pH, Redox) in connection with measuring/control devices type D1C, D2C or direct connection to PCs or PLCs.

  • Drinking water treatment
  • Wastewater treatment
