The paper describes an automated setup for measurement of magnetostrictive strain in ferromagnetic plates and films. The setup uses standard foil strain-gauges and allows the strain measurement in the range 1–2000 ppm at magnetic field up to 2 kOe. Temperature of the sample under test is stabilized with 0.05$^\circ$С accuracy and can be varied from 10$^\circ$С to 80$^\circ$С. The sample can be rotated, settling the angle between its axis and magnetic field direction in the range 0$^\circ$–90$^\circ$C. The setup was used to measure magnetostriction vs. magnetic field dependences for metglas, nickel, and permendur plates. The magnetostriction over field derivatives were calculated, which are important for study of magnetoelectric effect in composite structures.
