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 PK2X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 PK2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。

PK2X運(yùn)用:
The CHECK?LINE® Pocket Strobe™ Model PK2X is a highly stable instrument for taking non-contact RPM measurements and inspecting moving parts by “freezing" or “slowing down" the action.
CHECK-LINE的PK2X是一款袖珍式頻閃儀,性能穩(wěn)定可靠,不用接觸旋轉(zhuǎn)中的物體便可對(duì)其進(jìn)行測(cè)量。
The PK2X requires only one hand to operate, yet delivers performace comparable to much larger and heavier “pistol-grip" type models. The PK2 is ideal for industrial, laboratory, R&D and academic environments. Its small size and excellent performance provide superior convenience and value — at a reasonable price.
PK2X單手便可操作使用,其性能并不亞于體型更大的槍柄式頻閃儀。其小巧的外形和物美價(jià)廉的特性使得PK2X成為工業(yè)生產(chǎn)、試驗(yàn)研究和學(xué)術(shù)環(huán)境中的。
