| Abstract: | A portable type TSP sampler is designed according to the market demand. The sam- pler uses STC12CSA60S2, an enhanced 51 core SCM as controller, customized section type large screen LCD as displayer. Automatic constant flow sampling is achieved with using the chip of HXT1 l, a 24 bit A/D converter, and M1210, a differential pressure sensor, and uses the flow dif- ferential signal to control the air pump. |
