PRESSURE SENSOR

摘要

The present invention relates to a pressure sensor that can visually figure out a certain level of pressure without using a complicated mechanical, electrical, and chemical device. A pressure sensor (100) includes a first member (110) that can be deformed by pressure of a fluid (200) in an object (300) of which pressure is measured, and a housing (120) that is placed opposite to the object (300), with the first member (110) being interposed between the object and the housing. The housing is formed in a dome shape and has a second hole on the surface thereof. The second hole is formed on the top of the housing.
