摘要： A pressure sensor includes a sensor body with a sensor chamber in the interior, at least a first separating membrane, forming a first separating membrane chamber connected with the sensor body. A measuring membrane divides the sensor chamber into two chamber portions. A pressure transfer liquid, with which the first separating membrane chamber, the first chamber portion and a channel therebetween are filled, in order to transfer a pressure to the measuring membrane; wherein the pressure sensor is specified for a temperature range between a minimum temperature and a maximum temperature, as well as for a pressure range. At the minimum temperature, the pressure transfer liquid volume in the first chamber portion, the first channel and the first separating membrane chamber is sufficient over the total pressure range to transfer the pressure to the measuring membrane, without the first separating membrane coming to rest, and that when, in the case of overload at maximum temperature, the entire pressure transfer liquid volume moves out of the first separating membrane chamber into the first chamber portion, and is accommodated by the measuring membrane, the measuring membrane experiences no plastic deformation.
