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-2000LED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 DS-2000LED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。

Designed for maximum performance, portability and ease of use, the Checkline DS-2000LED is a hand-held battery powered LED Digital Stroboscope for use in speed measurement as well as for motion analysis. It is fitted with seven (7) state-of-the-art, super-bright LEDs mounted in a precision-machined aluminum head with optimized optics, providing the highest light output of similar strobes on the market. Produces up to 3000 Lux! 
美國(guó)Checkline的DS-2000LED是一款為發(fā)揮其性能而設(shè)計(jì)的數(shù)字頻閃儀，便攜性好（手持式），操作簡(jiǎn)單，電池供電，用于速度測(cè)量和運(yùn)動(dòng)分析。DS-2000LED配備了7個(gè)的LED燈，亮度超高，安裝在精加工地鋁制頭里面，并對(duì)其進(jìn)行光學(xué)優(yōu)化，提供亮度的輸出，亮度達(dá)3000 Lux。

The Check-Line DS-2000LED can operate even at the highest flash rates for up to six hours continuously on a single set of three (3) standard AA-batteries . Keypad controls adjust flash rate in single increments as well as special keys for 2X and ÷2 functions. Other user-programmable settings include flash duration, phase shift, delay and much more. 
DS-2000LED能夠在閃光頻率下連續(xù)不間斷工作6小時(shí)，只需要安裝3個(gè)標(biāo)準(zhǔn)AA電池。同時(shí)，我們通過(guò)按鍵來(lái)控制閃光頻率，雙倍增加鍵（2X），雙倍減小鍵（÷2）?？蛻?hù)也可以自行設(shè)置不間斷閃光時(shí)間，相移和延遲等。

Supplied in a high-impact plastic with rubber protective sleeve providing additional protection as well as improved grip for the operator. Lifetime LEDs do not wear-out or need replacement making this product ideal for use on the factory floor, in the field or in the laboratory. Applications include ideal for speed, motion and vibration analysis, on rotating shafts, fans, cams, hi-speed motion analysis for speakers or ink-jet printing and more.

DS-2000LED的外殼為高強(qiáng)度塑料材質(zhì)，并配置橡膠防護(hù)套提供額外防護(hù)，增加手持強(qiáng)度。LED燈的壽命不會(huì)衰減，也省去更壞的煩惱，使得DS-2000LED成為工廠現(xiàn)場(chǎng)和實(shí)驗(yàn)室應(yīng)用的。頻閃儀的用途很廣，主要是旋轉(zhuǎn)軸，風(fēng)扇，凸輪，揚(yáng)聲器和噴墨打印機(jī)上的速度、運(yùn)動(dòng)和振動(dòng)分析。
