TERMINOLOGY
|
Process Connection |
External means to connect protection tube to process system. Tubes can be threaded, bolted (to matching flange), or welded in place. |
|
Instrument Connection |
Means to connect temperature instrument to protection tube. Typically male pipe threaded. |
|
“U” Dimension |
Length of protection tube immersed into process system. Measured from the base of the process connection to the end tip of the tube. |
|
“H” Dimension |
Also called “head length”. Measured from the base of the process connection to the face of the instrument connection. |
|
“S” Dimension |
Instrument insertion length into protection tube. Equal to bore length. |
|
“D” Dimension |
Outside diameter of protection tube. |
|
Bore Diameter |
Inside diameter of protection tube. |
