一种袖珍型电子秤的设计

为解决现代商业贸易和日常生活中经常遇到的测量小质量物体的重量问题,介绍了一种新型的袖珍式电子秤的设计。此袖珍式电子秤采用测力传感器将重力信号转换成电信号来测量,并将测量结果进行数字显示。该袖珍式电子秤具有体积小、重量轻、携带方便、显示直观、测量精度高等优点;也有结构复杂,成本高等缺点。本文主要阐述了称重传感器的工作原理、误差补偿、主要参数选择。并进行了技术经济性分析。

Design of a Kind of Pocket Electronic Balance

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.
