Ceramic pressure measuring cell with at least one temperature transducer and pressure measuring transducer with such a pressure measuring cell
2015
A pressure measuring cell comprising: a ceramic counter-body (3); a ceramic measuring diaphragm (2) which is joined to the counter body (3) to form a measuring chamber between the counter-body (3) and the measuring diaphragm (2) by means of a revolving joint (4) pressure-tight manner, wherein the measuring diaphragm deformable by a pressure to be measured is; an electrical transducer for converting a pressure-dependent deformation of the measuring diaphragm into an electrical signal; and a temperature transducer for providing at least one dependent on a temperature or a temperature gradient of the pressure measuring cell electrical signal, characterized in that the temperature transducer comprising at least a first thermocouple comprising a galvanic contact between a first conductor, a first electrically conductive material (14) and having, a second conductor of the at least comprises a second electrically conductive material.
