Patent attributes
A pressure pickup comprises: A diaphragm seal module having a diaphragm seal platform and a separating diaphragm, which is secured to the diaphragm seal platform to form a pressure chamber; a temperature sensor for registering a diaphragm seal temperature; a sensor module having a pressure measuring cell; a pressure line between the pressure chamber and the measuring cell, for loading the measuring cell with the pressure being measured; a housing, which is spaced from the diaphragm seal module and has a housing chamber in which an electronic circuit is arranged, which has inputs for signals of the pressure measuring cell and of the temperature sensor; and a canal, which extends between the housing chamber and the temperature sensor, wherein at least one electric line runs through the canal for coupling of the temperature sensor with the circuit, wherein the canal and the housing chamber form an enclosed volume, which is explosion-protected relative to the environment.
