Zusammenfassung:The invention relates to a sensor (10) for sensing at least one property of a fluid medium (12) in at least one measurement space (14). The sensor (10) comprises a sensor element (18) having at least one heatable membrane (20) and an electrical measuring bridge (48). The diaphragm (20) is connected to the electrical measuring bridge (48). The sensor (10) is also designed to sense a resistance of the measuring bridge (48). The sensor (10) is further designed to sense a pressure of the fluid medium (12) on the basis of the sensed resistance of the electrical measuring bridge (48). 提出一种用于感测在至少一个测量空间(14)中的流体介质(12)的至少一个特性的传感器(10)。所述传感器(10)包括具有至少一个能加热的膜片(20)和电测量桥(48)的传感器元件(18)。所述膜片(20)与所述电测量桥(48)连接。所述传感器(10)还构造为用于感测所述测量桥(48)的电阻。所述传感器(10)还构造为用于基于所述电测量桥(48)的感测到的电阻来感测所述流体介质(12)的压力。
