Abstract

Disclosed is a pressure measuring device, whose pressure sensor is protected against thermomechanical stresses, comprising a carrier, a support body arranged on the carrier, a pressure sensor arranged on the support body, a first joint including a joint material connecting the support body with the pressure sensor, and a second joint including a joint material connecting the support body with the carrier. The support body has on a face opposite the pressure sensor a first groove configured such that the first groove surrounds a joint area of the support body. The joint area of the support body and a footprint of the first joint are essentially equally large and significantly less than a base area of the pressure sensor opposite the first joint.
