PRESSURE TRANSDUCER Russian patent published in 1994 - IPC

FIELD: pressure measurements. SUBSTANCE: pressure transducer has evacuated case 1 and cap flexible member 2 with two-layer dielectric 3 and resistance strain gauges fitted on end face. Thickness h of cylindrical part of cap flexible member is chosen from equation: h = H/Ln[(d+2h)/d]-d/2, where H - thickness of end face part of flexible member, and d - inner diameter of cylindrical part of flexible member. EFFECT: enlarged operating capabilities. 5 dwg
