意大利ATOS放大器E-ME-AC-05F 21/3庫存                                                                                 ATOS放大器其中用得zui廣泛的是電子放大器。隨著射流技術(shù)（見射流元件）的推廣，液動(dòng)或氣動(dòng)放大器的應(yīng)用也逐漸增多。電子放大器又按所用有源器件分為真空管放大器、晶體管放大器、固體放大器和磁放大器，其中又以晶體管放大器應(yīng)用zui廣。在自動(dòng)化儀表中晶體管放大器常用于信號(hào)的電壓放大和電流放大，主要形式有單端放大和推挽放大。此外，還常用于阻抗匹配、隔離、電流-電壓轉(zhuǎn)換、電荷-電壓轉(zhuǎn)換（如電荷放大器）以及利用放大器實(shí)現(xiàn)輸出與輸入之間的一定函數(shù)關(guān)系（如運(yùn)算放大器）。                                                                                                                                      ATOS放大器型號(hào)編碼：
"E-ME"→歐板式電子放大器
"AC"→控制形式：用于開環(huán)或閉環(huán)控制
"01F"→電磁鐵：01F=用于單電磁鐵比例閥，05F=用于雙電磁鐵比例閥
"-"→選項(xiàng)：無標(biāo)記=標(biāo)準(zhǔn)對(duì)稱斜坡，/RR=有可調(diào)不對(duì)稱斜坡，-4=有4個(gè)輸入信號(hào)電位器，/RR-4=帶上升和下降斜坡及4個(gè)信號(hào)電位器，/4R-4=帶4個(gè)斜坡和4個(gè)信號(hào)電位器，/I=適用于輸入信號(hào)為4~20mA的電流信號(hào)
