摘要
本文介绍一种利用霍尔开关和单片机,采用二级译码选通循检的方式,测量油水界面和油液面仪器,直接采用数字量传输省去A/D转换过程或复杂的编码过程,其原理结构清晰简捷,元器件便宜,整个仪器具有较高的性能价格比。
A kind of instrument for measurement interface of petroleum and water is introduced in this paper. It is composed by UGN3020(Hall switch sensor) and 80C552 microcontroller. The method of two grade coding selecting date is used in the instrument.
