BURKERT8220型電導(dǎo)率/電阻率傳感器,寶德8220型電阻率傳感器,寶德傳感器
burkert兩線制電流變送器的輸出為4～20mA，通過(guò)250Ω的精密電阻轉(zhuǎn)換成1～5V或2-10V的模擬電壓信號(hào).轉(zhuǎn)換成數(shù)字信號(hào)有多種方法，如果系統(tǒng)是在環(huán)境較為惡劣的工業(yè)現(xiàn)場(chǎng)長(zhǎng)期使用，因此需考慮硬件系統(tǒng)工作的安全性和可靠性。系統(tǒng)的輸入模塊采用壓頻轉(zhuǎn)換器件LM231將模擬電壓信號(hào)轉(zhuǎn)換成頻率信號(hào)，用光電耦合器件TL117進(jìn)行模擬量與數(shù)字量的隔離。同時(shí)模擬信號(hào)處理電路與數(shù)字信號(hào)處理電路分別使用兩組獨(dú)立的電源，模擬地與數(shù)字地相互分開(kāi)，這樣可提高系統(tǒng)工作的安全性。利用壓頻轉(zhuǎn)換器件LM231也有定的抗高頻干擾的作用。
