横梁式天平的灵敏度取决于横梁和读数装置的灵敏度。按变换原理工作的现代天平读数装置可分为:机械式、光学机械式、光电式和电子式。光电读数装置是由刻线标尺或具有循环二十进制码的编码变换器发出电脉冲。此脉冲用
The sensitivity of a beam balance depends on the sensitivity of the beam and reading device. According to the principle of transformation of modern balance reading device can be divided into: mechanical, optical mechanical, optical and electronic. Optical reading devices are engraved rulers or encode transformers with cyclic binary codes that emit electrical pulses. This pulse is used
