Patent abstract
The invention relates to a pressure transmitter for an overload-proof pressure gauge, comprising a base body, a separating membrane disposed on a pressure-sensitive side of the pressure transmitter and subjectable to a pressure to be measured, a communicating chamber located inside said base body, which receives a pressure transmission medium, said chamber being closed on the pressure-sensitive side by the separating membrane, wherein the coefficient of thermal expansion of the pressure transmission medium is established in such a way that a temperature-induced change in the volume of the communicating chamber equals a temperature-induced change in the volume of the pressure transmission medium.
