  Forces in Various Single Plane Trusses

  This set enables the distribution of the forces in various plane trusses to be investigated using the universal test frame . A useful range of member lengths saves time-consuming adjustment. The members can be quickly and sturdily connected to joint discs using special snap action connectors. For the measurement of the force, all members are equipped with strain gauge bridges. The measuring amplifier is required to display the forces in the members and to further process the measured values on a PC. A set of cables to connect strain gauges and the amplifier is included. The trusses can be loaded using a spindle drive with a ring dynamometer and strain gauge.

  Cam Analysis Apparatus

  The allows the dynamic investigation of cam mechanisms, as used in motors for actuation of the valves. The cam mechanism consists of 4 interchangeable cam plates and 2 different tracers. A mass and a spring are used to simulate the valve. In order to demonstrate the so-called “valve wobble”, the spring rate, mass and speed are adjustable within broad limits. A plotter allows the actual lift curves to be recorded. The open design allows the observation of every detail of the movement process. A stroboscope (not supplied) can be used to provide a particularly impressive view of the movement process and lift. The unit is intended for demonstration purposes in technical education. It is not suitable for use as a test stand for fatigue testing.

  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.

  Pendulum Impact Tester 300Nm

  The pendulum impact testing machine is a solid unit specially designed for engineering lectures. It is used for performing the notched bar impact bending test with increased impact energy up to 300Nm. Two impact energy settings are available using an additional weight on the hammer. With this unit, a quality test can be performed on different metallic materials. The unit can, however, also be used for non-metallic specimens. The notched bar impact work required to deform the specimen can be read off directly from a trailing pointer on a large scale. An electromechanical two-hand trigger increases safety for the user. As an accessory, the system can also be equipped with an electronic goniometer, a measuring amplifier and software so that measured values can be read out on a PC and evaluated there.
