Pressure Transmitter- Temperature Rating
Pressure Transmitter- Temperature Rating
(OP)
I am installing Rosemount 3051S Pressure Transmitter on hot air duct. The air temperature is 400 deg C. I am using 3/8" impulse SS tubing. Pressure Transmitter temp rating is around 100 deg C. I know installing certain length of SS tubing will reduce temp. But how much, I do'nt know. Can anyone help me on this? Some book/white paper reference is appreciated.

If you find the white paper, please let me know.

The process world's 'manifold cooking' has better heat control through careful adjustment of the equalizing valve :')

Any tip or link you find let me know. Thanks

If condensate builds up in the line the other way, it will at the minimum introduce a zero error equivalent to the height of the condensate column in the sensing line. If it's pure water, it might freeze in there, and is it has dissolved substances, it could solidify -either way you lose the true reading and get a false reading. Could lead to a hazardous condition.

I have actually installed rosemount transmitters with direct mount kits directly above surface areas that contain well over 400C process. It is a matter of getting the right sized standoff.
