Delta Ohm DO9765T 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. The accurate design and choice of components make the instrument precise and reliable for a long working life. The instrument works with a pH electrode or Redox and a temperature probe (Pt 100 sensor, 100 Ω at 0°C).
