| 发明名称 | Thermal protection element for a pressure sensor | ||
| 摘要 | The invention relates to a thermal protection element (1), which is arranged on the front side for protecting a diaphragm (11) of a pressure sensor (10) to which pressure is applied. According to the invention, the thermal protection element (1) has, in the region of the sensor diaphragm (11), lamellae (2) which run parallel or are configured as circular arc segments (8) and cover 40% to 60% of the diaphragm surface, with the ratio between the cross-sectional height (h) of the lamellae (2) and the cross-sectional width (b) thereof being 8:1 to 12:1. | ||
