The transmissions in the individual gear steps are not implemented with planetary gear trains, but with spur gears. In the cutaway torque converter, one sees the pump and turbine wheel, the free wheel and the converter lockup clutch. A very extensive description of the function is supplied. The shifting processes are initiated electronically, with the gears being shifted by hydraulic clutches via theelectro-hydraulic control unit.

The trainer enables the measurement of air humidity with four different instruments which can be directly compared to each other: two different hygrometers, a capacitive hygrometer and a psychrometer. There are different measuring methods to determine humidity. Psychrometers operate based on the principle of evaporation cooling and compare the ambient temperature with the wet bulb temperature to determine the humidity. The measurement of the air humidity plays an important role in many branches of industry, e.g. during drying or in the air conditioning of buildings and vehicles. Hygrometers utilise the property of specific fibres, e.g. hair, to expand with increasing air humidity. The core element of the trainer is a climatic chamber with transparent door. In the capacitive sensor the dielectricity constant of a layer and with it its capacity changes due to the water molecules absorbed. This chamber can be humidified and dehumidified and contains the four instruments.

Industrial Machines Control Assembly Training Stand Kit
....
The two-stage gear unit kit contains all the parts required to construct the gear unit. All parts are clearly laid out and well protected in a sheet-steel tool box. Small parts are supplied in a box with a transparent lid. This assembly exercise permits wide-ranging and, above all, interdisciplinary work to be carried out by the students. It consists of a spur gear stage as its input, with a downstream worm gear stage (multistage gear combination). The fit seatings of the gear unit are designed to allow the complete assembly process to be carried out by hand. This, in conjunction with students working in an independent capacity, as well as developing team working skills, ensures that the unit serves as an excellent learning tool. The project unit is particularly well suited to action-based teaching.
