Wiring the dissolved oxygen (DO) sensor

The input module for DO measurement is suitable for different types of DO sensors:

i. Galvanic sensors like model DO30G
ii. Polarographic sensors like HAMILTON’S Oxyferm and Oxygold

The connection is as follows:

11 TC +

TC -

+ anode galvanic

- cathode galvanic

+ anode polarographic

shield

- cathode polarographic
