Said deformation measuring element (3) one end region is mounted in a holder (1), which is provided with edge guides (2) of the elongated formation, whereby said deformation measuring element (3) is provided with the elongated formation central guide (32). The holder (1) and the deformation measuring element (3) are formed by flat bodies, whereby said deformation measuring element (3) is situated in said holder (1) plane extending in the direction of the holder (1) length, whereby said elongated formation central guide (32) is mounted from at least one side of the sensor and parallel to said transversal through cavity (20) in the deformation measuring element (3) and on the same sensor side there are mounted in said holder (1) and on both sides of said elongated formation central guide (32) and parallel thereto the elongated formation extreme guides (2).
