時(shí)代TT120超聲波測(cè)厚儀是集當(dāng)代科技電子技術(shù)和測(cè)量技術(shù)于一體的、XJ的無(wú)損檢測(cè)儀器,采用微電腦對(duì)數(shù)據(jù)時(shí)行分析、處理、顯示,采用GAO度優(yōu)化的測(cè)量電路,具有測(cè)量精度GAO、范圍寬、操作簡(jiǎn)便、工作穩(wěn)定可靠等特點(diǎn)。TT110超聲波測(cè)厚儀可對(duì)各種板材和加工零件作精確測(cè)量,廣泛應(yīng)用于石油、化工、冶金、造船、航空、航天等各個(gè)領(lǐng)域。
TT120超聲波測(cè)厚儀基本原理
探頭發(fā)射的超聲波脈 沖到達(dá)被測(cè)物體并在物體中傳播,到達(dá)材料分界面時(shí)被反射回探頭,通過(guò)精確測(cè)量超聲波在材料中傳播的時(shí)間來(lái)確定被測(cè)材料的厚度。
TT120超聲波測(cè)厚儀主要功能
自動(dòng)校對(duì)零點(diǎn),可對(duì)系統(tǒng)誤差進(jìn)行修正;
非線(xiàn)性自動(dòng)補(bǔ)償,利用計(jì)算機(jī)軟件對(duì)探頭非線(xiàn)性誤差進(jìn)行修正,以提GAO測(cè)量準(zhǔn)確度;
設(shè)有耦合狀態(tài)提示、低電壓提示、自動(dòng)關(guān)機(jī)等功能。
