日(rì)本歐姆龍產品詳解:
日本歐姆龍常州代(dài)理OMRON壓力(lì)傳感器(qì)
OMRON傳感(gǎn)器是(shì)采(cǎi)用光電元件作為檢測元件的傳感器。它首先把(bǎ)被測量的變化轉換成光信號的變化,然後借助光電元件(jiàn)進一步將光信號轉換成(chéng)電信號。光電傳感器一般由光源(yuán)、光學通路和光電元件(jiàn)三(sān)部分組(zǔ)成。由光通量(liàng)對光電元件的作用原理不同所製成的(de)光學測控係(xì)統是(shì)多種多(duō)樣的(de),按(àn)光電元件(光學測控係統)輸出量性質可分二類,即模擬式光電傳感器和脈衝(開關)式光(guāng)電傳感器.模擬式光電傳感器是將被測量轉換 光電傳感器(qì)成連續變化的光電流,它與被測量間呈單值關係(xì).模擬式光電傳感器按被測量(liàng)(檢測目標物體)方法可(kě)分為(wéi)透射(吸收)式,漫反射式,遮光式(光束阻檔(dàng))三(sān)大類.所謂透射式是指被測物體放在光路中,恒光源發出(chū)的光能量穿過被測物,部份被吸收後,透射光投射到光電元件上;所謂漫反射式是指恒光源發出的光投射到被(bèi)測物上,再從被測物體表麵反射後投射到光電元件上;所謂遮光式是指當(dāng)光源(yuán)發出的光(guāng)通量經被測物光遮其中一部份,使投射剄光電元件上的光通(tōng)量改變,改變的程度與被測物體在光路位置有關. 光敏(mǐn)二極管是zui常見的光傳感器。
光敏二極管的外(wài)型(xíng)與一般二極管(guǎn)一樣,隻是它(tā)的管殼上開有一個嵌著玻璃的窗口,以便於光線射入,為增加(jiā)受光麵(miàn)積,PN結的麵積做得較大,光敏二極管工作(zuò)在反向偏置的工作狀態下,並(bìng)與負載電阻相串聯,當(dāng)無光照(zhào)時,它與普(pǔ)通二極管(guǎn)一樣(yàng),反向電流很(hěn)小(<µA),稱為光敏二極管的(de)暗電流;當有光照時,載流子被激發,產生電子(zǐ)-空穴,稱為光電 光電傳感器載流子。在外電場的作用下,光電載流子參於導電,形(xíng)成比(bǐ)暗電流大得多的反向電流,該(gāi)反向電流稱為光電流。光電流的大(dà)小與光照(zhào)強度(dù)成正比,於是(shì)在負載電阻上就能(néng)得到隨光照強(qiáng)度變化而(ér)變化的電信號。 光敏三極管除了具有光敏二極管能將光信號(hào)轉換成電信號的功能外,還有對電信(xìn)號(hào)放大的功能。光敏三級管的外型與一般三極管相差不大,一般光敏三極管隻引出兩個極——發射極和集(jí)電極,基(jī)極不引出,管殼同樣開窗口(kǒu),以便光線射入。為增大光照,基(jī)區麵積做得很大,發射區較小,入射光主要被基區吸收。
工作(zuò)時集電結反偏,發射結正(zhèng)偏。在無光照時管子流過的電流為暗電流Iceo=(1+β)Icbo(很小),比一般三極管的穿(chuān)透電流還小;當有光照(zhào)時,激發大量的電子-空穴對,使(shǐ)得基極產生的電流Ib增大,此刻流過管子的電流稱為光電流,集電極電流Ic=(1+β)Ib,可見光(guāng)電(diàn)三極管要比(bǐ)光電二極管具有更高的靈敏度。
