US 12,140,605 B2 · Measuring device, sensor unit and method for determining at least one parameter of a medium

Abstract

A measuring device with a measuring tube is disclosed. The measuring device includes a sensor unit for capturing a parameter of a medium, a control and evaluation unit, and a deflectable measuring sensor with a cavity and a base unit. The sensor unit is at least partially integrated in the wall of the measuring tube. The measuring sensor is connected to the base unit via a spring element. The base unit is arranged outside of the measuring tube. A side of the measuring sensor is in contact with the medium during operation. The cavity is arranged on the side of the measuring sensor facing the medium. The measuring sensor is integrated into the measuring tube wall in such a way that it can be deflected at least in the plane of the measuring tube wall. The sensor unit has a means for capturing the deflection of the measuring sensor.
