The sensor, intended to detect de pressure of a medium, employs at least one element modifying its resistance value under the effect of a pressure. Said element is an ordinary resistive element, preferably a coal layered resistance, a thin layered resistance or a thick layered resistance. The elements (21) are preferably arranged in a bridge circuit wherein, in order to compensate for the temperature influences and to increase the pressure-dependent signal, resistive elements are used which have different temperature and pressure coefficients. The resistive elements are further arranged in a support (32) which may be resiliently deformed under the effect of the pressure, so as to obtain an increase of the signal by the conjugated effect of the pressure and an expansion, respectively of a deformation of the resistive element. |
