The invention relates to a measurement technique, in particular, to means of controlling the linear dimensions of parts from elastic and non-conducting materials in mechanical engineering, and is an improvement of the invention according to the author. St. N; 1522018.

The purpose of the invention is to improve the accuracy and stability of the control.

FIG. 1 shows a device for controlling the linear dimensions of elastic parts; FIG. 2 shows a measuring element with an electrically conductive plate and insulators attached thereto, and a contact element fixed in an elastically deformable element, side view, section view.

The device comprises a bar with a scale and a fixed measuring element 1 mounted with the possibility of movement along its axis. the movable measuring element 2 .. moving along

a rod and an electric contact indicator made in the form of two pairs of conductive plates 3 connected in pairs in an electric circuit, diametrically fixed in the lower part of measuring elements 1 and 2 and insulators 4 insulated from them, and two pairs also connected in pairs in an electric circuit fixed cantilever in an elastically deformable elemental under the arm to the working surface of measuring 1 and 2 contact elements 6, electrically insulated from them by insulators 7. A LED is mounted on the movable measuring element 2 d 8 for supplying light Gurr Nala touching the measuring elements 1 and 2 of the surface of the controlled object.

The device works as follows.

To control the linear dimension of the part, the measuring elements 1 and 2 with anti-VJ

opposite sides approach its surface. After the working surfaces of the contact elements 6 touch the surface of the tested part and the subsequent movement of the measuring elements 1 and 2 to it, the lower part of the contact elements b moves towards the electrically conductive plates 3 due to the elastic deformation of the element 5, and the distance between the upper part of the contact elements 6 and the working surface of the measuring elements 1 and 2 at their points of contact with the insulators 7 remains unchanged. At the moment of contact of the lower part of the contact elements 6 with the electrically conductive plates 3, the electric circuit of the device,
