頻閃儀是指控制光源發(fā)光，以特定頻率快速閃動(dòng)的光學(xué)測(cè)量?jī)x器。美國(guó)

頻閃儀是指控制光源發(fā)光，以特定頻率快速閃動(dòng)的光學(xué)測(cè)量?jī)x器。美國(guó)Checkline DS-12V頻閃儀本身可以發(fā)出短暫又頻密的閃光,當(dāng)調(diào)節(jié)頻閃燈的閃動(dòng)頻率,使其與被測(cè)物的轉(zhuǎn)動(dòng)或運(yùn)動(dòng)速度接近或同步時(shí),被測(cè)物雖然高速運(yùn)動(dòng)著,但看上去卻是緩慢運(yùn)動(dòng)或相對(duì)靜止,這種視覺(jué)暫留現(xiàn)象使人目測(cè)就能輕易觀測(cè)到高速運(yùn)動(dòng)物體的表面質(zhì)量與運(yùn)行狀況 ,而頻閃儀的閃光速度即為被檢測(cè)物體(例如:馬達(dá) )轉(zhuǎn)速和運(yùn)動(dòng)頻率 (印刷袋 ) ,亦可以利用頻閃儀分析物體振動(dòng)情況、高速移動(dòng)物體的動(dòng)作以及高速攝影等。利用頻閃儀觀測(cè)檢驗(yàn)技術(shù)在歐美已廣泛使用 ,隨著我國(guó)經(jīng)濟(jì)的高速發(fā)展,越來(lái)越多的行業(yè)開(kāi)始使用頻閃儀來(lái)幫助解決產(chǎn)品質(zhì)量檢驗(yàn)問(wèn)題。

Check-Line DT-311A 頻閃儀也叫頻閃靜像儀或轉(zhuǎn)速計(jì) ,是能夠使作振動(dòng)、高速旋轉(zhuǎn)或周期運(yùn)動(dòng)構(gòu)件變成“ 靜止不動(dòng) " 構(gòu)件的一種光學(xué)測(cè)量裝置。

Check-Line DT-311A Flash Range: 40-35,000 RPM/FPM

Checkline DT-311A Portable, highly stable and accurate, industrial-quality tools for non-contact RPM measurement, inspection and observation of moving parts by "freezing" or "slowing down" the action.

AC-Powered version for use hand-held or can be fixed-mounted using the supplied 1/4-20 Threaded insert or using the optional Articulating arm accessory (model SAS-DT300).

Other models offered with built-in (Checkline DT-315A) or external battery (Check-Line DT-315AEB).
