A device for measuring stresses is known, which contains an elastic element with strain gauges connected by a bridge circuit and a recording device {ij. The disadvantage of this device is the impossibility of simultaneously measuring stresses in an elastic element and registering the moment of destruction of a material. It is also known a device for measuring mechanical characteristics during f fatigue tests, containing an elastic element with a vacuum concentrator, on which the strain gauges in the breakdown detectors, turned on in the shoulder of the bridge circuit. destroy the material, but it has a number of disadvantages. First, it is imperative that you should have a resistance greater than that of a strain gauge, which is not always achievable and inconvenient in practice. Secondly, with the destruction of the detectors, only a small change in resistance occurs, which makes it difficult to register the moment of destruction. The purpose of the present invention is to increase the output signal with pa; crushing materials. The LAI of this destructive signaling device is made in the form of a low-resistance wire, the resistance of which is in the order of resistance to the strain gauges, and the strain gauge in the destruction signaling device is included in the shoulder of the bridge, respectively.
