:德陽(yáng)2098-DSD-HV030 AB伺服驅(qū)動(dòng)器 羅克韋爾生產(chǎn)廠家PLC系統(tǒng)中使用的模擬量有兩種,一種是模擬電壓,一種是模擬電流,模擬電壓常見(jiàn),用的也多。模擬電壓一般是0~10V,并聯(lián)相等,長(zhǎng)距離傳輸時(shí)容易受干擾,一般用在OEM設(shè)備中。模擬電流一般是4~20mA,串聯(lián)相等,抗干擾能力強(qiáng),dcs系統(tǒng)中一般都使用模擬電流。首先,我們先要用傳感器測(cè)量我們所需要的參數(shù),變送器將此參數(shù)變換成0~10V或者4~20mA,現(xiàn)在很多傳感器都是自帶變送器的,直接就輸出模擬量,建議大家在項(xiàng)目中選用此種類型的傳感器圖二某壓力傳感器手冊(cè)如圖二所示,是某壓力開(kāi)關(guān)的選型手冊(cè),紅色圓圈部分是它的量程0~250公斤,再看黃色熒光筆部分,此型號(hào)的傳感器是模擬電流輸出,也就是此款傳感器將0~250公斤的壓力線性轉(zhuǎn)換成了4~20mA的電流,當(dāng)我們檢測(cè)到12mA的電流時(shí),就表示壓力是125公斤,依此類推。
