| 摘要 |
The invention relates to a sensor unit comprising a measuring cell (1) having a surface which is heat-conducting at least in parts, a housing (3; 4, 5, 6, 7) in which the measuring cell (1) is largely contained, and at least one access channel (2) to the measuring cell (1). Said sensor unit is characterised in that is has a cavity (8) which is mostly defined by an outer surface of the measuring cell (1) and by a wall of the housing (3; 4, 5, 6, 7) which is oriented to the surface of the measuring cell (1), said cavity (8) being closed therein. |
