BURKERT8220型電導率/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250Ω的精密電阻轉換成1～5V或2-10V的模擬電壓信號.轉換成數字信號有多種方法，如果系統是在環境較為惡劣的工業現場長期使用，因此需考慮硬件系統工作的安全性和可靠性。系統的輸入模塊采用壓頻轉換器件LM231將模擬電壓信號轉換成頻率信號，用光電耦合器件TL117進行模擬量與數字量的隔離。同時模擬信號處理電路與數字信號處理電路分別使用兩組獨立的電源，模擬地與數字地相互分開，這樣可提高系統工作的安全性。利用壓頻轉換器件LM231也有定的抗高頻干擾的作用。
