PH or mV Configurable Transmitters

DO9765T pH transmitters convert the output of a pH electrode, with temperature compensation, into a 4÷20 mA signal. The transmitter is completely configurable and for use on the field. Dimensions 122 x 120 x 57 mm with dual LCD (measurement + temperature), output 4…20 mA insulated with 2 wires passive or 4 wires active. Power supply in active mode 24 Vac, on request 230 Vac, in passive mode 10…35 Vdc. The pH electrode input circuit is galvanically insulated against the 4÷20 mA output signal. The LCD indicator allows viewing of the process signal value and of the various parameters.
