DULCOMETER® Shaft Transmitters

DULCOMETER® Shaft Transmitter are compact 2-wire measurement transmitters without display and operation for pH, Redox, Temperature and Fluoride measurements. The transmitters may easily be combined with 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 insensitive non-calibrated 4...20 mA signal.
Easy installation directly on the respective sensor

Application Areas

Measurement signal transfer over long distances or at transmissions of disturbance sensitive measuring signals (e.g. pH, Redox) in connection with measuring/control devices type D1C, D2C or direct connection to PCs or PLCs.
Drinking water treatment
Effluent water treatment
