摘要： PROBLEM TO BE SOLVED: To provide an accurate pressure sensor reduced in the sizes of the height and diameter.
SOLUTION: A high pressure and small-sized pressure sensor 10 has a cup-shaped housing 12 having an open end closed by a metal substrate 14. A raised stress isolation pedestal portion 14d is formed on the substrate that receives a stress isolation glass pedestal element 18 and in turn a silicon pressure sense element 22, all having closely matched CTEs to minimize temperature inducing stresses. A fluid passageway is formed through the substrate and glass pedestal and an O-ring 15 is placed around the passage on the lower side of the substrate. A flexible circuit having a slit tail formed with two lobes for receiving respectively in the housing and on the substrate allows easy access of a solder iron during assembly. Mounting flanges extend from the substrate to facilitate mounting of the sensor and minimize transfer of mounting stresses to the sense element.
