Abstract

Sensor structure of a flow body protruding into a current for carrying out measurements of flow states, containing a structural part (1) with at least two measuring orifices (5), to which transfer lines (7) are coupled, which guide the flow medium from the measuring orifices (5) to a pressure converter system (13) for the purpose of determining the flow states. The outer shell (3) of the structural part (1) contains two areas (21, 22), which are arranged behind each other viewed in the direction of flow, wherein the first area (21) has greater thermal conductivity than the second area (22). Within the first area (21) heating elements (31) are arranged on the structural part (1), and are connected with a temperature control circuit with the temperature on the surface of the first area (21) as a control variable.
