The moisture content of substance is an important indicator to determine the physical,chemical and biological characteristics of the substance,and accurate measurement of moisture content has important significance.The exist moisture analyzer cannot satisfy the precision of measurement and the real-time performance of weighing simultaneously.A weighing module of moisture analyzer based on CS5532 is designed and the working principle of weighing module is discussed,and the hardware circuit design is described in detail.The experimental results show that the moisture analyzer based on this designed module has quick response of test result and well real-time performance with precision of 0.1mg.The moisture measurement error is less than 0.1%,the response time is less than 0.4s and the stabilization time is less than 5s.
