A solid frame made of anodised aluminium section forms the base for the unit. The bearings for the pulleys and gears are attached to the t-slots in the profile using clamping levers. This apparatus is used to demonstrate belt drives, wheel and disk drives, and gear trains. Basic terminology and relationships, e.g. the transmission ratio, direction of rotation reversal, reference circle and modulus, the function of intermediate gears, and so on can be clearly demonstrated. The size of the unit ensures that the experiment is clearly visible even for larger groups of students. These are easy to release and can be slid horizontally making a wide range of different set-ups possible. All experiments are carried out using manual power.

The flow rate is measured using a magneto-inductive flow sensor. In this way the system provides a whole host of measured data that permit students to perform experiments on the basic principles of a hydraulic circuit. The Trainer Centrifugal Pump Apparatus is a mobile system with a closed water circuit that is intended both for training in vocational colleges and also for laboratory experiments in higher education. Manometers indicate the pressure on the intake and delivery side of the pump. The system is equipped with a centrifugal pump and various transducers, e.g. the torque on the shaft of the speed-controlled pump motor is measured and indicated on the switch box, as is also the rotational speed, current and voltage.

The Oil Pump Supply Module is part of an equipment series that facilitates the investigation of a wide range of engines and machines. The flow is adjusted on a pressure valve and recorded using an oval wheel meter. Other sensors measure the temperature, intake and delivery pressure. Different oil pumps can be operated on the supply module and investigated in terms of their characteristic behaviour. The corresponding sensor connections and digital displays are located on the measuring equipment block. The pumps are connected into the experimental set-up using hydraulic hoses with quick action couplings.
