Second, capillary lines also serve the function of a cooling element in that a very hot or cold fluid equilibrates to a less extreme temperature as it travels through the line.<\/p>\n

As a general rule of thumb, a diaphragm seal will protect a measuring instrument from temperatures between -40\u00b0F and +300\u00b0F. A heat-sink type cooling element is typically added to the assembly at temperatures between +300\u00b0F and +500\u00b0F.<\/p>\n

A capillary line can be coiled and used together with a Diaphragm seal for measurement of processes at extreme temperatures above 500\u00b0F to 750\u00b0F.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
