The unit includes a metal bar with additional sliding weights as a rigid pendulum. The suspension point can be adjusted at the knife edge bearing of the pendulum. The length of the thread pendulum included can be easily varied using a clamping device. The model is used to investigate the oscillation of pendulums. During this process a physical pendulum is compared with a mathematical pendulum. The model is suitable for student experiments. The components of the experiment are attached to a base plate intended for wall mounting.

The unit itself includes the electric drive motor with speed control, 2 pressure vessels for the compressor experiments, a measuring tank and a supply tank for the pump experiments and a protection cover. The intake and delivery pressure, temperature, motor speed and power are measured and displayed digitally. The modular system allows the investigation of different machines (reciprocating machines and turbo machines). The corresponding flow is measured indirectly and transferred to the PC data acquisition software. Each machine is mounted on a base plate, which can easily be fitted into the unit. It is powered by a belt drive. Hoses with quick-action couplings provide the supply lines.

Pressure variations are made by the rotary vane pump which is provided with needle valves at entry and discharge. A further valve is incorporated at the pump outlet with pressure tappings either side of it to enable differential pressure measurements to be made and plugs are supplied to blank off any connections not in use. The apparatus consists of a series of pressure/vacuum measuring instruments mounted on a wheeled bench with an electrically driven rotary vane pump to provide the necessary pressure and vacuum. The bench also includes a microprocessor based portable digital pressure calibrator for pressures between -1 and 10 bar. The measuring instruments include a sloping, liquid filled manometer reading pressure from 0 to 75mm of water, a vertical manometer reading from 0 to 200 mm of water, a manometer reading from 0 to 760 mm, a pressure transducer with analogue readout and a Bourdon tube gauge scaled - 1 to 2.5 bar for reading both pressure and vacuum.

The dialogue between the semaphores of the two roads allows the alternation of the green signal as a function of the traffic intensity, while the pedestrian crossing is on request. The automatic control of the semaphore system is performed through PLC not with the normal cyclic timing: only the presence of at least one car determines the green signal of the relevant semaphore, allowing the transit of all the cars between the two detecting sensors. Smart Traffic Lights Simulator system represents a crossing between two one way streets, each controlled by a semaphore and provided with three pedestrian crossings with semaphores, too. The present cars are displayed through LED, whose control is assigned to an electronic circuit separated from the PLC.
