The Radial Heat Conduction accessories have been designed todemonstrate the application of the Fourier rate equation to simple steady-stateconduction radially through the wall of a tube.
Hardware Description:
The accessory comprises a soliddisk of material, which is heated at the centre and cooled at the periphery tocreate a radial temperature difference with corresponding radial flow of heatby conduction.
Six K-type thermocouples arepositioned at different radii in the heated disk to indicate the temperaturegradient from the central heated core to the periphery of the disk.
The arrangement, using a solid metal disk with temperature measurementsat different radii and heat flow radially outward from the centre to theperiphery, enables the temperature distribution and flow of heat by radialconduction to be investigated.
The heater power and the cooling water flow rate are controlled via,either from the front panel or from the computer software. These are controlledmanually.
A control valve permits the flowof cooling water to be varied, if required, over the operating range of 0-1.5l/min.
The cooling water flow rate ismeasured by a turbine type flow sensor .
An optional cooling water flowrate sensor Set 2 is available upon request for the connecting directly intothe service unit.
The radial distance between eachthermocouple in the disk is 10mm.
Quick-release connectionsfacilitate rapid connection of the cooling tube to a cold water supply. Apressure regulator is incorporated to minimise the effect of fluctuations inthe supply pressure.
The unit provides different configurations of control gears, which serve as an introduction togear engineering. The unit focuses in particular on the practical assembly ofgear components. The exercise system can be used to configure six differentgears in various combinations. Control gears are also known as variable or change gears.They are characterised by the fact that the speed is transferred differentlyvia various pairs of gear wheels. The most famous example is the transmissionin a car, which has one pair of gear wheels for each gear. The setup of the components is flexible so thatyou can configure your own ideas and try out different gears. The unit is driven by a handcrank. A solid frame made of square steel tubes and various bearings ensuressufficient accuracy to be able to set precise tooth interlocking. Allcomponents of the exercise system are ready at hand and securely housed in astorage system. Individual activities such as understanding the task and reading the drawing, assemblingthe components, adjusting, calibrating and checking the gear, and performingcalculations are performed one after the other.

The apparatus has two transparent tanks, mounted one above the other. A variable-speed pump transfers water from the reservoir (in the base of the unit) into the upper tank. PLC Process gives students and engineers practical experience of the principles and application of programmable logic controllers (PLCs). The object is to connect and program an external, programmable logic controller to monitor and control the level and flow rate of water in a two-tank system. The pump control is on or off, but a manual control allows the user to set the speed. A float switch in the reservoir monitors the level of water. The water can drain down to the lower tank and then back into the reservoir. Solenoid valves may be individually opened or closed to control and redirect the movement of the water.

The DC motor speed controller is built with a single phase semi-controlled thyristor bridge suitable for the control of the speed of independently excited DC motors by regulating the conduction period in open and closed loop. The DC motors are used in a wide variety of industrial drives, such as robots, machine tools, oil drilling rigs, mining, automotive systems, etc. The controller consists of three control loops: speed, current and armature voltage. Their speed can be easily adjusted in very fine increments ranging from standstill to rated speed and even above and their construction is made rather complex than their AC counterparts by the fact that they need acommutator, which reverses the direction of current and fluxes to produce a net torque.

This experimental unit forms part of a series of teaching systems developed in collaboration with the Department of Automation and Information Technology at the Harz University of Applied Studies and Research. A rotary encoder determines the position of the vehicle from the rotation of its wheels. This in turn activates an actuator, the drive motor on the vehicle. A vehicle with an inverted rod pendulum acts as a mechanical multi-variable system. A fuzzy control moves the rod pendulum to the centre position, where it is held in position, and at the same time controls the position of the vehicle. A joystick can be used to control the system manually. This allows the degree of difficulty of the control process to be estimated very accurately. The control process is made more difficult by the fact that the vehicle can only move to a limited extent from its original position.
