Xianyu Wang · Light Industry Machinery · 2007
In order to solve the weight measuring problem of small quality objects which often meets in moderncommercial trades and daily life,this text has introduced a new kind of designs of pocket type electronic balance.This pocket type electronic balance adopts the dynamometry transducer to change the gravity signal into an electric signal measurement,and will measure the result and carry on the digital display.The pocket electronic balance have many advantages,such as:small,light and carrying convenient,revealing intuitional and the higher measuring precision and so on.There are also some shortcomings,such as:too complicated structure,the high cost.This text has mainly explained and weighed the working principle of the transducer,the error compensating,the main parameter choosing,and has carried on technological economy analysis.
