  Strain Gauge Training System

  Strain gauges are used extensively in sensor systems to detect forces, moments and deformations. The FL 100 experimentation system provides a comprehensive introduction to the fundamentals of strain gauges. Three test specimens for tension, bending and torsion are each fitted with three strain gauges. The strain gauges are wired into a full bridge configuration. A defined load is generated with the aid of weights, and the elongations can then be recorded. The specimens under test can be inserted quickly and precisely into the mounting frame. The strain gauge application area is protected by a Plexiglas cover, which also makes it clearly visible for inspection purposes. The measuring amplifier unit delivers the bridge supply voltage, and displays the load-dependent output voltage. The digital display is programmable, to provide readouts conforming to the variables being measured. It also features a tare function to exclude the influence of preloads. All detachable test components are clearly laid-out and well-protected inside a storage box.
  The well-structured instructional material outlines the technological fundamentals and provides a step-by-step guide through the experiments.

  Universal Material Tester

  This material tester is a benchtop unit for training purposes. Simple operation and robust construction make the unit suitable for student experiments. The test spectrum for the basis unit covers tensile tests, and also Brinell hardness testing. Using the accessories that are also available, additional bending, shear, cupping and compressive tests can be performed. PC data acquisition and evaluation is also possible. The basic version of the unit does not require any additional sources of power. The test load is generated using a hand operated hydraulic system. The test load is displayed using a large gauge and a trailing pointer. The elongation of the test specimen is recorded via a mechanical gauge. The unit features a clear layout and the rapid changing of accessories.

  Experimental Set Portal Frame

  The set is intended for use with the universal test frame and demonstrates the elastic deformation of loaded frames. The test specimens are a U-shaped and and S-shaped frame made of steel with a square cross-section. These are subjected to varying loads using sets of weights and the resulting deformation measured. For this purpose, the set includes two precision position measurement gauges. The bearings can be either fixed or free enabling the frames to be evaluated as statically defined or undefined systems. The experimental set-up is quickly and securely assembled using special clamps.

  Transmitted Light Polariscope

  Using this transmitted light polariscope, photoelastic experiments can be performed. This process exploits the fact that the refractive index of photoelastically sensitive materials changes under mechanical stress. Transmitted polarised light experiences a rotation of its plane of polarisation, this results in lines in the material subject to the same stress being of the same colour. The distribution of the stress in the model can thus be clearly seen. The polariscope can either generate coloured stress diagrams using white light or, using monochromatic light, light-dark diagrams. The filters, which have angular scales, can be rotated in a holder mounted on rollers. On the side is a pointer using which the angular position can be read off. Light sources, polarisation filters and load frames are separate components on this unit. Thus it is possible to realise flexible experimental set-ups also with own models.
