Rosemount Transmitter water intrusion
Rosemount Transmitter water intrusion
(OP)
Hello I have a Rosemount transmitter used for flow (0-250" H2O). It is getting water inside of the 4-20mA module side only. It gets about a teaspoon/tablespoon of water in it. Eventually it shorts/corrodes the module and I have to replace it. I have tried absolutely everything! I have replaced the transmitter, sealed it completely with and without the conduit/flex sealed. Placed a housing over the top. Covered it with insulating fabric and duct tape... We have redundant units only one transmitter does this. Any suggestions would be great! Thanks in advance!

What stream are you measuring?
What quantity are you measuring?
What is the range, and units?
What model transmitter?
Is there a water source outside the measured stream?

Try drilling a hole to let the water out.

Bill - My next step was to drill a seep hole, BUT my inquiring mind wants to know a cause for the water intrusion. Condensation is the only thing I can think of and that still doesn't seem to make sense because it is a lot of condensation in a little area.
Thanks for the info.

Mike - I am with you and it is indeed sealed. This one is a true stumper!
Thanks for the feedback.

My operating hypothesis here is that some stranded wire includes anti-wicking treatment, and some does not, and you got some that wicks, and it has a water source somewhere.

Thealanator - No and no. The conduit comes up, I have even went as far as disconnecting and pointing the flex down to eliminate theory of the underground conduit filling with water.
