Pressure sensor without cooling

摘要

The pressure sensor has a housing (6) containing a measuring device separated from the housing by a radial gap. The measuring device includes a pressure transfer part (2), a measuring part and e.g. tubular springs for applying axial tension to the measuring part. The sensor also has a seal membrane which provides a sealed, rigid connected between the housing and the pressure transfer part. At least one heat conductor (7,8) is arranged between the pressure transfer part and the housing, and has high heat conductivity and large conducting cross- section. The heat quantity falling in the region of the pressure transfer part is mostly fed out via the heat conductor to the housing. The heat conductor acts as a bending or rolling part on axial movement between the pressure transfer part and the housing. This is weak in the axial direction w.r.t. force transmission.
