Pendulum Impact Tester
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, one of the classic material tests. In this way, quality can be tested and the fracture behaviour of different metallic materials evaluated. The unit is equally suited for use with non-metallic specimens. The notched bar impact work necessary to deform the specimen can be read off directly from the gauge on a large scale. A two-hand trigger increases the safety for the user. A protective cover for the working area and a PC data acquisition is also available. The educational advantages of the unit lie in its simple layout and direct visibility of all actions. Together with the other units in the WP range, this unit is part of a complete course on the fundamental principles of material testing.

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.

Sensor Supply Module
The sensor supply module is used to provide power to vibrations sensors. The module provides the necessary power and outputs the corresponding measured signals. Up to four sensors can be connected simultaneously using 7-pole DIN sockets. The analogue measured signals in the range from 1 to 9 Volts are output on 4mm laboratory sockets and can be displayed on a meter or an oscilloscope. The benchtop unit has a robust steel sheet housing with anti-slip rubber feet.

Shearing Force and Bending Moment Apparatus
This demonstration unit facilitates the experimental investigation of the progression of the bending moment and shearing forces on a bar subject to point loads. In addition, the section principle commonly used in mechanics can be demonstrated. Due to the use of a low friction joint with two degrees of freedom at 1/3 of the span and two dynamometers, the measurements can be recorded directly from the bar. The deflection of the bar as result of the travel of the dynamometers and the horizontal alignment can be compensated and regulated using two adjustment bolts. The bar is loaded with graduated sets of weights that can be attached at any point on the bar.

Shearing Force Apparatus
This demonstration unit facilitates the experimental investigation of the progression of the shearing force in a bar subject to point loads. Also the section principle commonly used in mechanics can be demonstrated. Due to the usage at 1/3 span of a low friction joint sensitive to shearing forces and a dynamometer, the measurements of shearing force on the bar can be recorded directly. The deflection of the bar as a result of the travel of the dynamometers and the horizontal alignment can be compensated and regulated using two adjustment bolts. The bar is loaded with graduated sets of weights that can be attached at any point on the bar. The support rollers are equipped with ball bearings

Static and Dynamic Balancing Apparatus
The main element of the benchtop unit is a smooth shaft to which four variable unbalance weights can be attached at any angle or distance. The rotor is supported horizontally in ball bearings and is driven by a speed-controlled motor. The speed is measured electronically and shown on a digital display. For determination of the unbalance weight by measuring the balance of moments the driving belt can be removed. Using different weights dragging on the pulley defined moments can be exerted to the shaft. They can be compared with those caused by the unbalance weights when rotating. The transparent hood prevents contact with the rotating parts and provides a good view of the rotor. Fastening of the supporting base with elastic elements neutralizes undesirable vibrations.

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.

Structures Table with Standard Roof Truss
This training unit is used to investigate loaded plane trusses and enables the member forces to be measured. A pre-assembled main truss is included. The trusses are assembled using joint discs to avoid bending loading. Seven of the members are equipped with full bridge strain gauges for the measurement of force. A strain gauge connecting box is included in which the offset error of the individual strain gauges is already compensated. The measuring amplifier FL 151 is required for measured signal conditioning. The loading device is mounted in bearings such that it can rotate, as a result it is also possible to apply forces at an angle. The unit is designed as an easy to operate table model. Another truss is available as an accessory, a laboratory trolley for storing the individual parts is also available.
