意大利ATOS放大器E-ME-AC-05F 21/3库存 ATOS放大器其中用得zui广泛的是电子放大器。随着射流技术(见射流元件)的推广,液动或气动放大器的应用也逐渐增多。电子放大器又按所用有源器件分为真空管放大器、晶体管放大器、固体放大器和磁放大器,其中又以晶体管放大器应用zui广。在自动化仪表中晶体管放大器常用于信号的电压放大和电流放大,主要形式有单端放大和推挽放大。此外,还常用于阻抗匹配、隔离、电流-电压转换、电荷-电压转换(如电荷放大器)以及利用放大器实现输出与输入之间的一定函数关系(如运算放大器)。 ATOS放大器型号编码:
"E-ME"→欧板式电子放大器
"AC"→控制形式:用于开环或闭环控制
"01F"→电磁铁:01F=用于单电磁铁比例阀,05F=用于双电磁铁比例阀
"-"→选项:无标记=标准对称斜坡,/RR=有可调不对称斜坡,-4=有4个输入信号电位器,/RR-4=带上升和下降斜坡及4个信号电位器,/4R-4=带4个斜坡和4个信号电位器,/I=适用于输入信号为4~20mA的电流信号
