Pressure sensor e.g. optical pressure sensor for measuring operating pressure of hot process fluid, has heat conducting portion with high thermal conductivity, formed between pressure transmission element and housing

摘要

The sensor has separate measuring device arranged radially through annular gap (4) in housing (3). The measuring device has measuring element (52) arranged behind the pressure-transmitting element (51) in the printing direction. A sealing membrane (6) is formed in annular gap between housing and the pressure transmission element, to seal the gap against process fluid. A heat conducting portion (7) of a material having a high thermal conductivity is formed between the pressure transmission element and the housing as a layer on or in component such as sensing element biasing spring.
