Heaters cylindrical cartridge

Details of the complete EC-DTA cell are shown in Figure 11.256. The heater block, which was machined from aluminum, contained a 500 W heater cartridge located in the center of the block. Two cylindrical chambers located on each side of the heater housed the sample and reference container, respectively. Care was taken to position each container at exactly the same distance from the heater. It was found from previous DTA studies that the diameter of the con tainer cavities greatly influenced the DT A curves obtained. In this cell they were 18 mm in diameter by 38 mm in depth. 

Cartridge heaters may be cylindrical or conical in shape (see Chapter 5.1). 

Cartridge heaters are cylindrical or conical in shape (see Figure 5.3). The external shape has an impact on many of the usage properties of heaters.
