Baumer strain sensors usually consist of a strain body and strain gauges. The strain sensor is screwed to a machine structure with screws. This machine structure deforms under the effect of force and this deformation is picked up by the strain body through friction, so that strains occur on the material surface. This strain is tapped by means of strain gauges applied to the surface of the measuring body. The strain gauges convert the mechanical strain into an electrical resistance change and act as a mechanical-electrical converter. By intelligently connecting the individual strain gages to form a Wheatstone measuring bridge, even the smallest strains can be detected. These strains measured with the aid of the strain gages thus generate a stress change proportional to the strain which can be easily evaluated with the aid of the integrated amplifier electronics.
