A complementing circuit selects either the subtracter output or the output of the complementing circuit . 取補(bǔ)線路可任意選通減法器的輸出或補(bǔ)取線路的輸出。
In the part of the transmitter , the pre - amplifier logarithmic amplifier , temperature complement circuit , anti - disturbing circuit , and v / i circuit , are discussed . the transmitter outputs 4 - 20ma . in the part of the displayer hardware design , the i / v convert circuit and the flame intensity signal processing circuit are introduced 在探頭的設(shè)計(jì)中,詳細(xì)介紹了前置對數(shù)放大器電路設(shè)計(jì),在對數(shù)放大器加入了溫度補(bǔ)償電路和抗干擾電路,以保證測量精度和較大的量程,最后信號(hào)經(jīng)電壓電流的轉(zhuǎn)換,得到4 - 20ma的標(biāo)準(zhǔn)信號(hào)作為探頭的輸出信號(hào),進(jìn)行遠(yuǎn)傳。
