The Base Unit (TD1002) is the core of the TD1002 range. It provides cold water and heater power to the optional experiments and all the instruments needed to measure their performance.
The Base Unit’s water system connects to a suitable cold water supply and drain. It includes a hand-operated valve to help give a controllable water flow and a simple return pipe, both colour-coded.
The water connections to the optional experiments are self-sealing quick connectors – for safety and simplicity. The inlet and outlet fluid streams have different colours to reduce errors. Changing an experiment takes less than a minute. The Base Unit provides a variable and measured electrical current to the heater in each experiment and works with a safety switch to stop the heater from becoming too hot. It also includes sockets for the thermocouples built into each optional experiment.
Clear, multi-line digital displays on the Base Unit show the temperatures and heater power of each experiment. A spare area to the right of the Base Unit frame allows you to fit the optional VDAS-F hardware.
Each optional experiment is on a bedplate that has a clear schematic diagram showing the connections and measuring point positions. The bedplate fixes to the Base Unit with thumbscrews (students need no tools).
Note: You need at least one of the optional experiments. You cannot do experiments with just the Base Unit. You can do tests with or without a computer connected. However, for quicker tests with easier recording of results, TecQuipment can supply the optional Versatile Data Acquisition System (VDAS®). This gives accurate real-time data capture, monitoring and display, calculation and charting of all the important readings on a computer.
