How to wire a Rosemount PH electrode?
Thread Content
The company is upgrading its environmental protection equipment and needs to measure the pH levels for desulfurization and denitrification processes. A new device has been added, but it’s not clear how to connect it; therefore, I’m seeking help from experts. The instrument model is Rosemount 1056, while the pH electrode model is Rosemount 396R-10-21-54.
You have 9 wires, while the wiring diagram shows 5; therefore it’s possible to cause a short circuit, so avoid doing that. I can only speak from my experience. Red, blue, white, and white represent a four-wire thermistor, corresponding to 1, 2, 3, and 4; use a multimeter to determine this specifically. Brown is connected to 8; its shield is connected to 7. Black is connected to 10; its shield is connected to 9. Yellow followed by 7
