Composite sensor for temperature and pressure measurement and manufacturing method thereof

摘要

It relates to a complex sensor for temperature and pressure measurement that is installed in a flow path and can measure temperature and pressure of a fluid at the same time. The complex sensor for temperature and pressure measurement includes an outer housing having an installation space therein; provided as a single part and coupled to the installation space of the outer housing, at least one fluid inflow passage is formed between the outer circumferential surface and the inner circumferential surface of the outer housing when combined with the outer housing, and communicates with the inflow passage therein an inner housing in which a connection pipe is formed; a temperature sensor unit provided in the inner housing to measure the temperature of the fluid; and a pressure sensor provided in the inner housing to measure the pressure of the fluid passing through the connection pipe.
