| Abstract: | With high performance and low power dissipation of MSP430 single chip computer,used as the top management chip of the characteristic of the qualitative dielectric coefficient in proportion to condenser capacity and by the measurement of a two-wire reeling capacitive sensor,the intelligent and low power dissipation media ratio instrument was designed.The non-linearity and temperature drifting characteristic of the measured data were clearly amended and compensated.The test result was delayed at LCD.The most obvious characteristics of this system is point are adopting two-wire reeling capacitive sensor to gather data and it is possible to measure the manifold physical water ratio. |
