An arrangement for measuring a fluid pressure, comprising a pressure sensor portion (10), which is devised for accommodation in a recess (12), which is open at least at one end, wherein the pressure sensor portion (10) in relation to the recess (12) is to be dimensioned in such a way that the pressure sensor portion (10) is surrounded by a gap (14) for receiving fluid, wherein first and second surfaces (16a, 16b, 18a, 18b), which are situated on the pressure sensor portion (10) and in contact with fluid, are so dimensioned and aligned that forces, which are exerted by the fluid pressure on the first surfaces (16a, 16b) and push the pressure sensor portion (10) in the direction of the open end of the recess, are equal to or lower than the forces, which are exerted by the fluid pressure on the second surfaces (18a, 18b) and push the pressure sensor portion (10) away from the open end of the recess (12).
