To satisfy this need, manufacturers now use solid state thermoelectric devices in computers, portable refrigerators and cool boxes. The increasing need for smaller and more portable electrically powered equipment has produced a need for low maintenance, smaller and more portable cooling.
The Thermoelectric Device Demonstrator shows how one of these devices works and tests its performance when connected in a choice of two modes:
Heat to electricity for power generation when used in See beckmode often used for thermoelectric generation and given the acronym.
The load allows generated power to flow and be measured for a range of applied temperature gradients.
As an electrically powered heat pump when used in Peltiermode. Often used in thermoelectric cooling and given the acronym.
Students then learn to analyse its performance in both modes, analysing several factors including coefficient of performance and energy balance. For the See beck tests, the equipment uses an external cold water source and variable power electric heater to create a temperature difference across the device. A switch allows tests with and without an electrical load. The device then converts this into an electrical potential difference.
Recording the curves of a Pelton turbine and investigating the influence of the nozzle cross-section
Force sensor at the turbine inlet
Transparent front panel for observing the operating area
Non-contact speed measurement at the turbine shaft and force sensor at the brake for measuring the torque
Loading the turbine by use of a band brake
Adjustable nozzle needle for setting different nozzle cross-sections.
The unit is perfectly self-sufficient, takes up little space and can be easily moved. The hydraulic circuit essentially consists of a high-head centrifugal pump, a flow meter, two pressure gauges theturbine with the transparent end shield, a supply tank and the connecting pipes. An electrically operated centrifugal pump transfers the water under pressure from the main tank to the turbine, simulating thehigh drop and low flowrate conditions as are typical of Pelton turbines. Pelton Turbine Study Unit study unit has been designed for a complete range of tests on Pelton type hydraulic turbines. The purpose of the system is to enable the students to work out the power and torque curves of a Pelton turbine. Next to the nozzle control hand-wheel there is aprofile reproducing the nozzle and the distributor needle on a 1 to 1 scale. A nozzle and a Double needle with hand-wheel control permit the fine adjustment of the turbine supply flow, whilst a jetdiverter makes it possible to prevent exceedingly high runaway velocities.

Pendulum Impact Tester
....-lab-1552900294.jpg "Pendulum Impact Tester (25J)")
Pendulum Impact Tester (25J) has an anvil and pillar which have replicable impact profiles for supporting the notched specimens prior to testing. A heavy hammer swings on a pre-defined radius, set by the hammer arm. A sturdy bench top mounted unit for the study of notched bar impact strength tests. The initial energy of the hammer can be varied by changing the starting weight and/or the start height of the hammers swing this can be varied between 3 set positions. A sturdy base plate with protective guard surround houses all the components, the guard has a lockable door for ease of access when setting the test but also security whist not in use. As the hammer swings through its radius, it impacts on the specimen and the distance it travels passed the specimen is measured on an integral scale shown in degrees.
Experimental Capabilities:
To determine notched impact energy absorption.
The influence of starting mass, starting height on the overall potential energy of the swinging mass.
Notched bar impact strength, Charpy test.
Understand the influence of materials and their properties on notched impact.
Observe and evaluate fracture surface characteristics from broken samples.
Understand the influence of notched shape and cross sectional area on the notched bar impact.

Peristaltic Pump Learning System versatile pump keeps fluid uncontaminated as it moves through the system by utilizing a tubing system that prevents direct contact with the pumps working parts. The Peristaltic Pump Learning System also discusses peristaltic pump components, how to reduce pulsation, how to calculate and adjust the flow rate, and how to select proper tube sizes. The Peristaltic Pump Learning System covers the function, operation, and maintenance of peristaltic pumps, which are used in a variety of applications within the chemical, food, pharmaceutical, and biotechnological industries. As an example, peristaltic pumps are used to filter and circulate blood throughout the body during heart surgery.
The Peristaltic Pump Learning System industrial-grade components are the same as those used in the field, so learners will gain experience and practice on actual, real-world mechanisms. The Peristaltic Pump Learning System features a foot-mounted peristaltic pump with polycarbonate housing and steel pump head, a maintenance key tool, and a piping network. Once completed, learners can proceed to additional pumps like the Piston Pump and the Gear Pump. Gear pumps transfer fluids under pressure and are used in hydraulic systems, pressure washing, and liquid recirculation. Piston pumps are used in water, soap, and detergent applications to produce high pressure fluid flow.
