FIELD: measuring equipment.
SUBSTANCE: proposed pressure sensor comprises a sensor body (2) made at least partially of an electrically insulating material with a first surface (2a) and a second surface (2b) located opposite to each other and a cavity (3) closed on at least its one axial end by a membrane part. The pressure sensor (1) comprises a circuit device (5) supported by the sensor body (2) and including: an arrangement of a first electric circuit containing corresponding tracks made of electroconductive material applied on the first surface from its external surface with respect to the cavity, wherein a plurality of components of the first circuit are connected to the first electric circuit including detection means for detecting bending or deformation of the membrane part; an arrangement (7) of a second electrical circuit comprising corresponding tracks (10, 11) made of electrically conductive material applied to the area of the second surface (2b), at that the arrangement (7) the second circuit is connected to at least one component (8; 8') of the second circuit having an active part (8) intended for fluid action and at least one first connection output (8b) and one second connection output (8B); and connection means electrically connecting the arrangement of the first electrical circuit to the arrangement (7) of the second electrical circuit and extending in the axial direction of the sensor body (2). The tracks (10, 11) of the arrangement (7) of the second electrical circuit include at least one first track (10) forming a plurality of first contact pads (10a) and one second track (11) forming a plurality of second contact pads (11a) for connecting the first output (8b) and the second output (8b) of the second circuit component (8; 8'), respectively. The first and second tracks (10, 11) are prepared in advance with provision of possibility of connection of the first output (8b) and the second output (8b) component (8; 8') of the second circuit with any of the first contact pads (10a) and with any of the second contact pads (11a), respectively, and/or to the first pad (10a) and to the second contact pad (11a) of any of the plurality of pairs of the first and second contact pads (10a, 11a), respectively.
EFFECT: creating a sensor having flexible structure that does not maintain residual deformation under the action of controlled medium.
