The unit consists of two vessels connected by a large bore pipe and valve together with an integral air pump. A small scale bench top accessory designed to allow experimental investigation of the first law of thermodynamics using the perfect gas law and the expansion of air. Additional valves allow the vessels to be used in isolation; venting to or from atmosphere and in a combined arrangement where the pressurised vessel can vent into the evacuated vessel. The pump can be used to both pressurise one vessel and evacuate the other.
Experimental Capabilities:
Observation of the transient responses to different rates of change in a process.
Observation of the Pressure, Volume, Temperature Relationship for Air.
Investigation of the First law of Thermodynamics.
The second Law of Thermodynamics and its Corollaries
The sides of the tank are supported and sealed by a well proven method which allows free access to the interior and results in minimum sight obstruction. The bed of the tank is made from painted mild steel. The ends of the tank are made of steel plate. One side is of toughened glass to give good scratch-free visibility over a long period of use while the other is made of aluminium which permits the insertion of pressure tapping points as required.
The equipment is self-contained, requiring only an initial fill with cold water and connection to the electricity supply. The sump tank can be emptied to a laboratory drain. These may be lowered to a position close to the bed of the tank for some experiments to provide sub-soil drainage. Adjustable overflows are provided close to each end of the tank so that constant water levels may be maintained in each half of the tank.
These measuring devices, along with a set of precisely-machined components, are used to complete skills, such as measuring length, taking accurate measurement of inside and outside dimensions, and collecting process data. This Portable Precision Gauging Learning System features calipers, micrometers, and a variety of gauges within a flexible, convenient product for situations where space is too limited for a full-size trainer or when a trainer is needed in multiple environments. Customers can additionally purchase the, which features a snap gauge.
Measurement is a cornerstone of all technical career paths and a major part of quality assurance, which helps to keep product quality high and costs low. Portable Precision Gauging Learning System covers the fundamentals of basic measurement, precision measurement, direct gauging, indirect gauging, and dimensional measurements using both the customary system and the SI metric system all within a mobile, highly durable product.

The plant includes a cabinet where switches and other electric control elements and rotections necessary to ensure the safety of people and equipment in accordance with current electrical regulations are installed. All the elements of the Plant For The Study Of Erosion Corrosion are mounted on a structure of about 1 m. (W) x 3 m. (L) x 1 m. (H), made of 40x40square tube in stainless steel, provided with selflocking wheels for easy movement and location.
Operation of the Plant For The Study Of Erosion Corrosion
Plant For The Study Of Erosion Corrosion tank is complete with stirring to keep the mixture in suspension, a heater for heating the fluid, a sensor, and a digital controller for controlling the parameters in the tank.
Water with suspended material is stored in a tank of 1000 L capacity made of stainless steel with drain valve and manhole for filling.
The suspension is driven by a second centrifugal pump of stainless steel with similar characteristics to the previous one through a pipe of about 65 mm. diameter, U shaped, built in plastic material or stainless steel and is returned back to tank, thus creating a closed circuit.
The recirculation flow of the liquid to the tank is controlled through a valve that regulates the flow of water driven to the pipe. The flow driven by the pump can be displayed on a rotameter.
The Plant For The Study Of Erosion Corrosion tank is thermally insulated to prevent heat loss. In order to fill the tank there is a centrifugal pump in stainless steel that gives a maximum flow of 45 m3 /h with a power of 1.5 kW.

Servo systems are closed-loop control systems. In many industrial applications it is often required to convert small mechanical motions into a different motions with increased force. The displacement of the carriage is established using a potentiometric position sensor and compared against the reference variable. The control deviation is processed in a separate servo amplifier. Hydraulic systems are particularly suitable for applications where large actuation forces are required. The unit allows the operation of a hydraulic servo system to be investigated in detail. A carriage with a mass of 50kg is moved by a hydraulic cylinder. Additional springs and an adjustable hydraulic damper permit static and dynamic loads to be simulated. The trainer is a mobile unit. Measuring devices can be housed in the built-under cabinet unit. Depending on the direction of the deviation, a control valve is activated in forward or reverse direction, which in turn produces a corresponding movement of the hydraulic cylinder and the carriage.

Heating and condensing takes place inside a partially filled glass vessel. A heater coil heats the water. The equipment heats and condenses water, and includes a separate control module with a digital display. For boiling heat transfer experiments, students adjust the current in a resistant wire heater element in the water. They note the free convection and the other stages. The temperature of the wire reaches significantly higher than 100 degree C. Students watch the boiling process and note the different boiling processes.
These include:
Film boiling unstable and stable, where a vapour blanket forms and heat transfer by radiation becomes important.
Sub cooled boiling where small bubbles form and rise.
Nucleate boiling where large bubbles form and rise.
The Computerized Air Conditioning And Climatization Study Unit has been developed for insertion in the most advanced educational subjects. The working principle of the apparatus is the following an air flow generated by a centrifugal fan enters a tunnel passing through a fluid thread rectifier. Simplicity and clearness are the fundamental requirements that permit the teacher and students to operate without having to deal first with complicated utilization procedures. As the air passes through the tunnel it undergoes a series of treatments, until it arrives in the last chamber which represents the environment to be conditioned. Before this last stage, it may be pre-heated and moisturized by water diffusers, to experiment on heating environments and to have the opportunity to vary as many parameters as possible for a complete study on air conditioning. The flow is pre-heated, then moisturized by steam diffusers it is cooled through the evaporator and sent to the final chamber.
