| Abstract: | An air-leakage test instrument is developed for accumulator case in this paper. The hardware of the instrument includes a chip of air pressure sensor MS5401-BZ, the measuring mechanism applied a cylinder driving reciprocating part and a chip of P89LPC938 which processing data and shifting AD. The test principle is direct measurement and one-key mode. The utilization of the instrument showed that it has specialities of good stability, simple operation and high accuracy. |
