RF-932X2B射頻導納物位控制器

產品(pin)簡介(jie)

射頻(pin)(pin)導納料位開(kai)關是目前國際物(wu)位控制器(qi)跨世紀的(de)(de)前衛替代產品，適用(yong)于測(ce)(ce)量液體(ti)、固體(ti)的(de)(de)位置高度,它提供DPDT的(de)(de)接點輸(shu)出,并且(qie)(qie)不受(shou)物(wu)料附著與(yu)探棒(bang)的(de)(de)影(ying)響(xiang)。此產品采用(yong)適當(dang)頻(pin)(pin)率(lv)的(de)(de)射頻(pin)(pin)信號，同(tong)(tong)時對電容、電阻(zu)、電感進行檢測(ce)(ce)，消除了采用(yong)電容式技術而無法避免的(de)(de)虛物(wu)位等(deng)誤差，且(qie)(qie)有多(duo)種不同(tong)(tong)形式。可適用(yong)于高溫振動、攪(jiao)拌、或狹小(xiao)的(de)(de)空間場所的(de)(de)測(ce)(ce)量。導納式物(wu)位開(kai)關為了克服附著物(wu)的(de)(de)影(ying)響(xiang)，特別(bie)于主電極與(yu)接地電極間多(duo)增加了一保護(hu)電極，以(yi)確保信號準(zhun)位的(de)(de)正(zheng)確。這(zhe)種特殊電極構造特別(bie)適用(yong)于各種不同(tong)(tong)物(wu)料的(de)(de)偵測(ce)(ce)，并且(qie)(qie)不受(shou)物(wu)料附著的(de)(de)影(ying)響(xiang)。

探(tan)棒常會(hui)(hui)遇到(dao)有(you)(you)(you)物料附著(zhu)于(yu)其上情形，并(bing)(bing)在三個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極間(jian)形成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容與(yu)(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻，因主(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極與(yu)(yu)(yu)保(bao)護(hu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極間(jian)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)位(wei)及波形一(yi)樣(yang)，所(suo)以不會(hui)(hui)有(you)(you)(you)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流通過兩電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)介質(zhi)，導納(na)式物位(wei)開(kai)關利用以上的(de)(de)(de)原(yuan)理，于(yu)主(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極與(yu)(yu)(yu)接(jie)地(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極間(jian)置一(yi)保(bao)護(hu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極，以阻擋射頻(pin)(pin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流經由(you)主(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極與(yu)(yu)(yu)接(jie)地(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極間(jian)的(de)(de)(de)介質(zhi)而(er)到(dao)達(da)桶壁(bi)。保(bao)護(hu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極與(yu)(yu)(yu)接(jie)地(di)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極間(jian)雖然會(hui)(hui)有(you)(you)(you)少量的(de)(de)(de)射頻(pin)(pin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流通過，但電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路并(bing)(bing)不會(hui)(hui)偵(zhen)測此(ci)一(yi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流值(zhi)。由(you)于(yu)保(bao)護(hu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)作用，只有(you)(you)(you)介于(yu)主(zhu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極與(yu)(yu)(yu)桶壁(bi)間(jian)所(suo)通過的(de)(de)(de)射頻(pin)(pin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流變化會(hui)(hui)被(bei)(bei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路所(suo)偵(zhen)測，因此(ci)當(dang)探(tan)棒接(jie)觸到(dao)物料時，會(hui)(hui)產生一(yi)準確的(de)(de)(de)信(xin)號準位(wei)，該信(xin)號準位(wei)的(de)(de)(de)大小與(yu)(yu)(yu)介電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)系數成(cheng)(cheng)正比，但與(yu)(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻值(zhi)成(cheng)(cheng)反比，此(ci)信(xin)號很容易被(bei)(bei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路偵(zhen)測出來，并(bing)(bing)輸出一(yi)控制信(xin)號。
