BURKERT容積式流量變送器/BURKERT8030型流量變送器
BURKERT容積式流量變送器的輸出為4～20 mA，通過(guò)250 Ω的精密電阻轉(zhuǎn)換成1～5 V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。
BURKERT容積式流量變送器同時(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。BURKERT容積式流量變送器大多為電壓輸出型，即將測(cè)量信號(hào)轉(zhuǎn)換為0-5V電壓輸出，這是運(yùn)放直接輸出,信號(hào)功率<0.05W,通過(guò)模擬/數(shù)字轉(zhuǎn)換電路轉(zhuǎn)換數(shù)字信號(hào)供單片機(jī)讀取、控制。但在信號(hào)需要遠(yuǎn)距離傳輸或使用環(huán)境中電網(wǎng)干擾較大的場(chǎng)合，電壓輸出型傳感器的使用受到了極大限制，暴露了抗干擾能力較差,線路損耗破壞了精度等等等缺點(diǎn)，而兩線制電流輸出型變送器以其具有*的抗干擾能力得到了廣泛應(yīng)用。
