The sesnor is a 'cheap & nasty' way of measuring the temperature of the LNG. When the Cryogenic lines on an LNG terminal are not being used they have to be constantly cooled so that they don't expand and contract every time they are used (i.e. every time an LNG ship exports LNG to the terminal)...
I am looking for information on the installation details of an RTD surface mount pad to measure temperature on crogenic lines. As the gas is liquid the obvious choice would be on the bottom of the pipe but someone has told me there could be the possibility of condensation running down the pipe...
