The Exhaust-Stack Particulate Sampler Microcomputer-Controlled Data Acquisition, Calculation, and Display System has been developed to provide the operator with continuous sampling information as particulate samples are taken. Data inputs to the microcomputer system are provided by sensors measuring temperatures, pressures, humidity, and velocity of a stack flowstream. The microcomputer system incorporates a single component microcomputer, a number-oriented microprocessor, a single-chip 16-channel analog-to-digital converter, a programmable keyboard/display interface, and liquid crystal displays. The scientific calculation capability and associated display have been incorporated to perform and display the results of 28 complex equations. These results allow the operator to maintain proper sampler probe temperatures, to maintain proper flow through the sampler probe, and to make sampler probe positional changes when necessary.
