寶德數(shù)字式電導(dǎo)率變送器選型資料,BURKERT8226型電導(dǎo)率變送器
寶德數(shù)字式電導(dǎo)率變送器選型資料因其結(jié)構(gòu)簡單、穩(wěn)定、壓損小。量程范圍寬等特點(diǎn)在液體測量中有著廣泛應(yīng)用。其原理是，當(dāng)液體經(jīng)過管道中的旋渦發(fā)生體時，所產(chǎn)生旋渦的振動頻率與流速成正比。在渦街流量變送器中，以壓電晶體或差動電容作傳感器，將檢測到的微弱振動信號放大、濾波、驅(qū)動后，輸出其頻率與瞬時體積流量成正比的脈沖信號，整個電路制成賀型印刷線路板，俗稱放大板。這種變送器適用于分散模式，每臺變送器配接1臺基于頻率檢測的流量積算儀。近年來許多企業(yè)已逐步采用儀器分布管理模式，這就要求多個測量點(diǎn)的流量信號統(tǒng)轉(zhuǎn)換成4－20mA，再送到計(jì)算機(jī)中集中臨近和管理，因此出現(xiàn)了二線制的4－20mA渦街流量變送器，它是在原來放大板后面連塊轉(zhuǎn)換板而成，轉(zhuǎn)換板由f / V和V / I電路組合，將原來放大板輸出的頻率信號轉(zhuǎn)換成4－20mA輸出。儀表系數(shù)非線性的影響傳感器輸出信號非線性是制約渦街流量變送器精度提高的zui重要因素，非線性造成各個流量區(qū)間表系數(shù)K不是常數(shù)。儀表系數(shù)定義為每立方米流量所發(fā)生的及沖數(shù)。變送器的非線性誤差定義為（Kmax－Kmin）/ （Kmax＋Kmin）×100%。通常，輸出脈沖頻率信號的常量變送器的準(zhǔn)確度標(biāo)稱只能達(dá)到1－2。而對于以電流輸出在渦街變送器，由于電路中f / V環(huán)節(jié)的加入，基于RC充放電的f / V轉(zhuǎn)換電路雖然有較高的分辨率，但線性及穩(wěn)定性卻滿足不了較高精度的轉(zhuǎn)換要求。
