Abstract

A pressure measuring sensor having a ceramic pressure sensor includes a temperature transducer to provide a thermovoltage dependent on a temperature gradient. The temperature transducer includes two series-connected thermoelements, each of which has a galvanic contact between a wire of the thermoelement and a connecting conductor connecting the galvanic contacts of the two thermoelements to one another. The temperature transducer enables the compensation for a measuring error caused by a temperature gradient occurring along the pressure measuring sensor.
