The basic module includes the electrical equipment and the components for the Level control. The Modular Process Control Trainer system is a modular and low cost trainer based on Personal Computer and suitable to study the Process Control techniques. It is possible to carry out the laboratory activity in an extremely productive way using the potential of a Personal Computer. Some additional kits allow to fulfill the Flow, Pressure, Temperature, pH and conductibility control by using most of the basic module components.

Main metallic elements in stainless steel.
The unit consists of three members, three node discs and a set of weights with a weight holder. Each member is formed by a longitudinally bar, a spring and a dial gauge. These bars can form numerous simple bar structures with different angles. The bar forces occurring during the exercises are measured by the deformation of the springs situated in the middle of the bar with the dial gauges.
The Unit for studying Forces in a Simple Bar Structure represents a simple bar structure that allows the measurement of bar forces and the comparison of the experimental results with the calculations and the graphical method.
The set of weights and a weight holder are used to apply external load in the upper disc of the simple bar structure.
The method of joints and the calculations are used to determine the bar forces in the different bar structure to compare with the experimental results.
The members are joined by three node discs such that the joints can move freely. Snap-locks allow to engage the bars in the discs. Two of the discs also form the support of the simple bar structure, it can move freely and is fixed to the section base of the unit.
The Area Moment Method Computer Interface set has the same accessories as Moment Supports are replaced by Moment Load Cells.
Computer interface unit and software are included.
A mark on the Simple Flywheel Apparatus and a pointer on the bracket enables the revolutions to be counted and timed with the stop watch supplied. From the timings of a known number of revolutions, students can then verify the expeirmental capabilities of the apparatus. A steel disc Ø250mm diameter and 30mm thick is mounted on a shaft running in precision bearings housed in a substantial wall bracket. A cord, load hanger and set of weights are provided to start the flywheel rotating.
Experimental Capabilities:
To compare experimental and calculated moments of inertia of a disc
To study the energy transformations and to demonstrate that a flywheel can be used to store energy
To verify the second law of motion applied to a flywheel, ie the relationship between torque and angular acceleration
A Double-Compressor Air Conditioning Cycle Training Bench for studying the theoretical and practical aspects of the air conditioning cycle and the control of two compressors operating at different powers.

A dye injection system allows four dye lines to be generated which highlights visualisation of flow lines and allows flow nets to be drawn for seepage analysis. Scales on the front panel assist in the preparation of models. Permeability Apparatus consists of a framed glass tank, of internal dimensions 1900 mm long by 530 mm high and 130 mm front to back. The base of the tank incorporates fourteen pressure tappings at 100 mm pitch, the tappings are specially designed to prevent the ingress of sand particles. Flexible tubes connect the tappings to two multitube manometer banks scaled 0 to 500 mm, for measure-ment of the water table height along the tank. The tank is mounted on a fabricated steel frame fitted with castors and levelling feet. The front, back and ends of the tank are of clear toughened glass giving scratch free visibility without the risk of abrasion of the inner surfaces by the permeable medium. Scales on the front panel assist in the preparation of models and in the prepara-tion and recording of flow nets. Washed silica sand graded 0.2 mm to 1.0 mm should be used as the permeable medium which must either be ordered separately from supplied by the end user. Coarser material may also be used. An activated carbon decolourising filter is provided in the sump tank to prevent the progressive dis-colouration of the water by prolonged use of dye.
