DOTX-45 Dissolved Oxygen System Part 10– Troubleshooting

DOTX-45 57 -

While the sensor is disassembled for membrane changing, examine the condition

of the o-rings on both ends of the electrolyte canister. If the o-rings show any

signs of damage, replace them with new ones from the spare parts kit. It is good

practice to change these o-rings once a year, regardless of their condition.

9.31 Lead Anode Replacement

Galvanic D.O. sensors consume the lead electrode during normal

operation. As oxygen is measured, lead is converted to lead oxide, and

after a period of time, the lead is expended. The lead electrode in the

D.O. sensor cartridge can be easily replaced, and replacement should be

done automatically every 12 months.

The lead electrode is the thick lead wire wrapped around the sensor body.

It is connected through a stainless steel post with a nut and star washer.

To change the lead electrode, remove the nut and washer and unwrap the

old lead. Loop the end of a new lead electrode around the post and

replace the nut and washer. Tighten the nut firmly but do not over tighten

as damage to the sensing module can result. Wrap the remainder of the

lead around the sensor body. There is no need to secure the other end of

the lead.
