描述
位移傳感器又稱為線性傳感器,是一種屬于金屬感應(yīng)的線性器件,傳感器的作用是把各種被測(cè)物理量轉(zhuǎn)換為電量。在生產(chǎn)過(guò)程中,位移的測(cè)量一般分為測(cè)量實(shí)物尺寸和機(jī)械位移兩種。按被測(cè)變量變換的形式不同,位移傳感器可分為模擬式和數(shù)字式兩種。模擬式又可分為物性型和結(jié)構(gòu)型兩種。常用位移傳感器以模擬式結(jié)構(gòu)型居多,包括電位器式位移傳感器、電感式位移傳感器、自整角機(jī)、電容式位移傳感器、電渦流式位移傳感器、霍爾式位移傳感器等。數(shù)字式位移傳感器的一個(gè)重要優(yōu)點(diǎn)是便于將信號(hào)直接送入計(jì)算機(jī)系統(tǒng)。這種傳感器發(fā)展迅速,應(yīng)用日益廣泛。
位移是和物體的位置在運(yùn)動(dòng)過(guò)程中的移動(dòng)有關(guān)的量,位移的測(cè)量方式所涉及的范圍是相當(dāng)廣泛的。小位移通常用應(yīng)變式、電感式、差動(dòng)變壓器式、渦流式、霍爾傳感器來(lái)檢測(cè),大的位移常用感應(yīng)同步器、光柵、容柵、磁柵等傳感技術(shù)來(lái)測(cè)量。其中光柵傳感器因具有易實(shí)現(xiàn)數(shù)字化、精度高(目前分辨率最高的可達(dá)到納米級(jí))、抗干擾能力強(qiáng)、沒(méi)有人為讀數(shù)誤差、安裝方便、使用可靠等優(yōu)點(diǎn),在機(jī)床加工、檢測(cè)儀表等行業(yè)中得到日益廣泛的應(yīng)用。
