比例阀是液压系统中的常用器件 ,它可以用电流的变化来控制输出的压力、流量。控制输入比例阀电流的器件 ,通常是应用电子式放大器 ,目前常用的台湾产的放大板—拨码盘组。本文介绍的“比例阀电脑控制器”是一种新型的比例阀电控器件。 (见本期插页广告 ) ,它应用微电脑来控制? Proportional valve is a commonly used device in the hydraulic system, it can use the current changes to control the output pressure, flow. Control input current proportional valve device, usually the application of electronic amplifiers, currently used in Taiwan amplification board - dial set. This article describes the “proportional valve computer controller” is a new type of proportional valve electronic control device. (See this page insert advertising), it uses a microcomputer to control?
