Pfeiffer IMR265 熱陰極離子真空計(jì)  的詳細(xì)介紹
按工業(yè)標(biāo)準(zhǔn)的定義,真空 (Vacuum) 就是 “ 低于一個(gè)標(biāo)準(zhǔn)大氣壓的氣體充滿空間的狀態(tài) ” 。如圖 1 : Overview of vacuum ,隨著壓力或單位體積內(nèi)分子數(shù)的減少,真空度的大小各不相同。

真空度的單位與壓強(qiáng)的單位一樣,用 Pa , mbar 等表示。有兩種表示方式:絕對(duì)真空度與相對(duì)真空度。一般說,用絕對(duì)真空度比較好理解,即準(zhǔn)確說出當(dāng)前的壓力和壓強(qiáng)是多少。對(duì)高低不同的真空進(jìn)行測(cè)量,所依據(jù)的原理也各不相同。

一、低真空度的測(cè)量原理

低真空度是指 1000 mbar ~ 1 mbar 范圍內(nèi)的真空。此范圍內(nèi),由壓強(qiáng)變化引起的壓力變化比較明顯,可以通過測(cè) 量力的變化來測(cè)量出真空度,如:薄膜真空計(jì),通過應(yīng)力片,感知設(shè)計(jì)好的薄膜上力的變化,得知當(dāng)前的真空度。如 Pfeiffer 的 CPT100 及 APR 系列 , 就應(yīng)用了 Piezo 膜應(yīng)力片,來檢知壓力的細(xì)微變化,從而測(cè)量出真空度。 電容真空計(jì),由于壓力不同,會(huì)引起電容兩極距離的變化,這會(huì)使電容的大小發(fā)生變化。這樣通過測(cè)量這種電容大小的變化,就能得知當(dāng)前的真空度。如 Pfeiffer 的 CMR 系列。

二、中真空度的測(cè)量原理

中真空度是指 1 mbar ~ 1*10 -3 mbar 范圍內(nèi)的真空。此范圍內(nèi),壓力的絕對(duì)大小變的不容易測(cè)得,但空氣的熱傳導(dǎo)能力顯的很有特點(diǎn)。這樣也有兩種方法可以測(cè)量出真空度:電容真空計(jì) (capacitance manometer) 通過調(diào)節(jié)預(yù)設(shè)壓力的大小,電容真空計(jì)可以完成中真空度范圍的測(cè)量。在 Pfeiffer 的 CMR 系列中, CMR 275 可測(cè)到 10 -5 mbar 數(shù)量級(jí)。 皮拉尼( Pirani )真空計(jì),中真空度條件下,空氣流動(dòng)的方式是層流,熱傳導(dǎo)能力與真空度線性對(duì)應(yīng)。因此可以通過測(cè)量恒溫電阻絲上的電流大小,測(cè)得真空度。如 Pfeiffer 的 TPR 系列,及一系列復(fù)合真空計(jì)中的低中真空探頭,都是采用的 Pirani 管。

三、高真空度或超高真空度的測(cè)量原理

高真空是指 1*10 -3 mbar ~ 1*10 -7 mbar 范圍內(nèi)的真空,超高真空是指 1*10 -7 mbar ~ 1*10 -11 mbar 范圍內(nèi)的真空。在這樣的范圍內(nèi),再去通過測(cè)量壓力的大小來測(cè)量壓強(qiáng),測(cè)量的精度及可靠性,就比較難實(shí)現(xiàn)。壓強(qiáng)的大小一方面體現(xiàn)為力的大小,另一方面還體現(xiàn)為單位體積內(nèi)分子數(shù)的多少。在高真空條件下,可以通過計(jì)量單位體積內(nèi)分子數(shù)的多少,來測(cè)知當(dāng)前的真空度。那么如何獲得單位體積內(nèi)的分子數(shù)呢?我們知道:電子在相同的電子能量,相同的磁場(chǎng)中,所引起的分子電離電流越大,說明分子數(shù)密度越大。離子真空計(jì)就是在高真空條件下,通過計(jì)量分子電離電流的大小來測(cè)得分子數(shù)密度,從而測(cè)得真空度。

離子真空計(jì)有兩種形式:冷陰極離子真空計(jì)( Cold cathode ionization vacuum gauge ),是通過加在陰陽兩極間的高電壓( 3 kv 左右),激出電子,同時(shí)這個(gè)電場(chǎng)又給了電子能量,用具有一定能量的電子去電離空氣分子。為了提高靈敏度,使得到的電離電流盡可能的大,一般將陰極做成空心圓柱狀,將針狀的陽極放在陰極中間,同時(shí)在陰極外圍設(shè)置磁場(chǎng)。這樣的條件下,電子的運(yùn)動(dòng)路徑會(huì)形成螺旋狀,電離空氣的機(jī)會(huì)大大增加,這樣就使得電離的電流盡可能的大,提高了真空計(jì)的靈敏度及精度。Pfeiffer 的冷陰極離子真空計(jì) IKR 系列,測(cè)量范圍為: 1*10 -2 mbar ~ 1*10 -11 mbar ,精度為: ± 30% reading ,重復(fù)精度: ± 5%.

熱陰極離子真空計(jì) (Hot cathode ionization vacuum gauge) ,是通過加熱陰極,激出電子,再設(shè)置一定的電場(chǎng)( 100 v 左右),給電子一定的能量,去電離空氣分子。熱陰極離子真空計(jì)在收集電離電流方面與冷陰極離子真空計(jì)有一些區(qū)別,并不是計(jì)量陰陽兩極間的電流,而是另外設(shè)置了電流收集器( ion collector ) , 結(jié)構(gòu)比較復(fù)雜,但測(cè)量精度特別是重復(fù)精度也相應(yīng)提高,如 Pfeiffer 的 IMR 265 ,重復(fù)精度達(dá)到了 2% reading 。離子真空計(jì)的使用需要注意:1. 測(cè)得的真空度與分子的種類有關(guān)。因?yàn)椴煌臍怏w,被電離的能力不一樣,讀取的真空度并不是最后的結(jié)果,需要按給定的系數(shù)進(jìn)行轉(zhuǎn)換后,才能得到正確的結(jié)果。為 Pfeiffer 的冷陰極離子真空計(jì) IKR / PKR 系列,在 10 -5 mbar 條件下的轉(zhuǎn)換公式及轉(zhuǎn)換系數(shù):Pfeiffer 的冷陰極離子真空計(jì) IKR 系列,測(cè)量范圍為: 1*10 -2 mbar ~ 1*10 -11 mbar ,精度為: ± 30% reading ,重復(fù)精度: ± 5%.熱陰極離子真空計(jì) (Hot cathode ionization vacuum gauge) ,是通過加熱陰極,激出電子,再設(shè)置一定的電場(chǎng)( 100 v 左右),給電子一定的能量,去電離空氣分子。熱陰極離子真空計(jì)在收集電離電流方面與冷陰極離子真空計(jì)有一些區(qū)別,并不是計(jì)量陰陽兩極間的電流,而是另外設(shè)置了電流收集器( ion collector ) , 結(jié)構(gòu)比較復(fù)雜,但測(cè)量精度特別是重復(fù)精度也相應(yīng)提高,如 Pfeiffer 的 IMR 265 ,重復(fù)精度達(dá)到了 2% reading 。
