Sensors -- Strain and displacement
			Strain and Displacement Transducers for Material Testings   Ensuring maximum utilisation of the materials employed in various designs and constructions has been a priority objective since the constant increase in the costs of energy and raw materials. This calls both for more precise assignment of material characteristics incorporating the latest findings in the area of material sciences and, as far as possible, practical simulation of the subsequent conditions of material use. In this context the measurement of strain and displacement has assumed special significance as it serves to establish fundamental values in terms of material characteristics. The measured data should be available in a suitable form for controlling the test test equipment and largely automated processing of these variables. Strain Transducers: Type A2.x    Example Displacement Transducers: Type WAB  Type WAC   Type WAD  Type WAE These requirements are met by the strain and displacement transducer system presented here, featuring a measuring element which operates on the basis of a foil strain gauge. It has a wide range of applications and is readily adaptable to the test requirements.
