Abstract
A quartz pressure sensor that resonates in the thickness-shear mode can include a center resonator structure and first and second caps joined to the center resonator structure by bond joints. Each bond joint is comprised of a sealing glass having thickness less than 0.0012 inches (˜30 μm) and a melting point less than 573° C. The quartz pressure sensor can additionally include an inner diameter edge feature formed between the interior sidewall in the joint sidewall of the caps that reduces stresses at the bond joints and/or a high stress point in the cap bore.
