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
