Hi,

I have an application of pressure transmitter at 410 deg C max. process temperature. Transmitter can withstand only up to 350 C at Atm pressure.
The original length of tubing for maximum working Temp of 310 C is shown in the attach file (Sketch B) and We are planning to extend the length of tubing
so the temperature will decrease from 410 C (process side) to 350 C or even to 310 C (at transmitter connection). Maximum ambient air temperature is 65 deg C. Maximum pressure we are measuring is 0.6 inH2O.
Is there anyone can help me to have the formula to calcualte the length of tubing, X in the attached sketch A?

Thank you.

Regards,
Edmund
