Process pH controller
pH/mV digital industrial transmitter
The pH transmitter converts the output of a pH electrode, with temperature compensation, into a signal at 4÷20 mA.
The pH or Redox electrode input circuit is galvanically insulated against the 4÷20 mA output signal.
An 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 or Redox electrode and a temperature probe (Pt100 sensor, 100 Ω at 0°C).
