寶德8175型超聲波液位計(jì),BURKERT流量計(jì),寶德液位計(jì)
寶德8175型超聲波液位計(jì)抗干擾能力極差，線路損耗的破壞,談不上精度有多高,有時(shí)輸出的直流電壓上還疊加有交流成分，使單片機(jī)產(chǎn)生誤判斷，控制出現(xiàn)錯(cuò)誤，嚴(yán)重時(shí)還會(huì)損壞設(shè)備，輸出０－５Ｖ不能遠(yuǎn)傳，遠(yuǎn)傳后線路壓降大，度大打折扣。現(xiàn)在很多的ADC,PLC,DCS的輸入信號端口都作成兩線制電流輸出型變送器4-20mA的,證明了電壓輸出型變送器被淘汰的必然趨勢。寶德8175型超聲波液位計(jì)的輸出范圍常用的有0～20mA及4～20mA兩種，電流變送器輸出zui小電流及zui大電流時(shí)，分別代表電流變送器所標(biāo)定的zui小及zui大額定輸出值。
BURKERT下面以測量范圍為以0～１００Ａ的電流變送器為例進(jìn)行敘述。對于輸出0～20mA的變送器0mA電流對應(yīng)輸入０Ａ值，輸出4～20mA的變送器4mA電流對應(yīng)輸入0Ａ值，兩類傳感器的20mA電流都對應(yīng)１００Ａ值。寶德8175型超聲波液位計(jì)大多為電壓輸出型，即將測量信號轉(zhuǎn)換為0-5V電壓輸出，這是運(yùn)放直接輸出,信號功率<0.05W,通過模擬/數(shù)字轉(zhuǎn)換電路轉(zhuǎn)換數(shù)字信號供單片機(jī)讀取、控制。但在信號需要遠(yuǎn)距離傳輸或使用環(huán)境中電網(wǎng)干擾較大的場合，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。
