The utility model belongs to the technical field of mechanics displacement measurement, in particular to novel displacement measurement device contains the casing, and locates the measuring mechanism in the casing, the measuring mechanism contain spheroid, pressure sensor, known object no. 1 and location object no. 2, inlay between casing and the spheroid and be equipped with a plurality of balls, known object no. 1 sets up in spheroid inner chamber middle part, pressure sensor lays at spheroid inner chamber side and known object between one, location object no. 2 sets up in the spheroid inner chamber bottom. The utility model relates to an it is novel, reasonable, realize simply that under the action of gravity, location object no. 2 makes spheroidal bottom be in bottom all the time to because ball effect makes the relative rotation between spheroid and the shell not receive to influence each other, guarantee that the dynamometric orientation of pressure sensor keeps invariable in the measurement process, carry out the displacement that the object was obtained in the integrated treatment through the pressure sensor measured data to obtaining, convenient to use, the suitability is strong, easily promotes implementation.
