The Computer Controlled Torsional Vibration Unit is an unit designed to study the torsional vibration, the torsional stiffness and the behaviour of a torsional vibration system with two and three torsional weight vibrator.
Vibrations are transmitted into the torsion bar by means of an electrical motor, which speed is computer controlled. The bar is supported by the base with movable pillars.
An adjustable damper can influence in the vibrations. Shaft encoders on the chucks provide the amplitude of vibration as an electrical signal.
Rigid weight discs, of several diameters and inertia, and pivoting bearings can be located at unlimited positions along the bar.
To facilitate the theoretical comprehension, the exercises are made with a metal torsion test bar, the main element of the unit.
Weight discs can be fixed to the bar with the aid of chucks and flanges; this way, it is possible to assemble torsional vibration systems with one, two or three weights.

The designed for training in ventilation engineering. The individual components in the ventilation system are fitted with pressure measuring glands. The power consumption of the fan is indicated on the switch cabinet using a voltmeter and an ammeter. For this purpose, an inclined tube manometer with 2 measuring ranges and a digital handheld unit for the measurement of the air velocity are included, along with numerous other components. Once the trainee has built a ventilation system independently, the effects of bends, branches, regulator flaps on the airflow rate, the air velocity, as well as the pressure loss can be investigated. The components are the same as those used in ventilation engineering.
