Claims

The goal is achieved by the fact that the electrocontact amplitude converter is equipped with a friction pair of brackets installed in a housing that can move parallel to the axis of the rod and form its middle part with the housing, one of the contact elements is fixedly movably fixed on one end of the contact and the other contact element. The drawing shows a diagram of an electric contact amplitude transform of bodies. The converter includes a housing 1 mounted in it a measuring rod 3 spring-loaded by means of a spring 2, a T-shaped bracket t rigidly fixed on it, the transverse part 5 of which has contact areas 6 and 7, a plunger 8 with tips 9 and 10 and the bracket 11, at one end of which the contact element 12 is installed and movably fixed, and the other contact element 13 is rigidly fixed on the other side. The converter works as follows. In the initial state, when the part T is controlled, is stationary, the spring 2 presses the measuring rod 3 to part N. The contact pads 6 and 7 are closed, respectively, with the tip 9 and with the contact element 12. The contact element 12 is moved in the axial direction to the position at which the gap between the tip 10 and the contact element 13 corresponds to the permissible value of the monitored parameter. During the measurement, the part 14 is driven into rotation and the measuring rod 3 transfers to the bracket 4 linear movements, which through the contact pad b cause the movement of the clamp 11, and through the contact pad 7 to the plunger 8 in the opposite direction. In the event that the actual value of the monitored parameter exceeds the allowable, then the tip 10 is closed with the contact element 13 and remains in this position until the end of the measuring cycle. If the actual value of the monitored parameter does not exceed the allowed one, then the closure of the tip 10 with the contact element 13 does not occur. The proposed converter has only two electrical contacts and ensures that the controlled parameter is memorized by closing the tip O with contact element 13, which increases the reliability of operation, simplifies the electrical circuit and provides a certain economic effect when implemented in production.
