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 QB-LED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 QB-LED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。

Flash range of 30 - 300,000 fpm (0.5-5000 Hz)

閃光范圍：30-300000FPM（0.5-500Hz）

The Check-Line QB-LED is a hand-held, battery-powered stroboscope featuring forty (40) extremely bright LEDs for the highest light output in its class. Designed for machinery observation, visual inspection and motion analysis, its robust design is suitable for use in the toughest industrial environments.

美國(guó)Checkline的QB-LED手持式頻閃儀集成了40顆高亮度輸出的LED燈，在同級(jí)別中性能優(yōu)異。QB-LED是靠電池供電，為機(jī)械觀測(cè)，肉眼檢測(cè)和運(yùn)動(dòng)分析而設(shè)計(jì)，外殼堅(jiān)硬，適應(yīng)于苛刻的工業(yè)使用環(huán)境。

The QB-LED features a robust aluminum housing fitted with forty long-life, high performance LEDs providing a peak brightness of 5000 Lux and convenient adjustment of flash duration to easily select the optimal balance of brightness and image sharpness. A built-in Lithium Ion battery provides up to seven hours of continuous use on a single charge. It is supplied with a universal battery charger (100-240VAC) with USA, Euro and UK plug adapters.

QB-LED的外殼材質(zhì)為鋁，裝載著40顆壽命長(zhǎng)，性能好的LED燈，其亮度達(dá)5000 Lux，并且方便對(duì)持續(xù)閃光時(shí)間進(jìn)行調(diào)整，輕松選擇平衡亮度和圖像清晰度。內(nèi)置的鋰離子電池，充電一次可不間斷使用7小時(shí)，還提供通用充電器（100-240VAC），有美標(biāo)，歐標(biāo)和英標(biāo)可供選擇。

The strobe is extremely easy-to-use, as functions such as flash rate and brightness adjustments are separated from the special functions that are found a separate menu. The special functions include phase shift, internal/external trigger selection, flash delay, divider and "Slow Motion" mode. "Slow Motion" Mode allows the user to offset the flash rate to put the "frozen" image into virtual "slow-motion".

QB-LED頻閃儀操作非常簡(jiǎn)單，用戶可以在菜單上尋找特殊鍵，直接閃光頻率和亮度進(jìn)行調(diào)整。這些特殊按鍵分別控制相移，內(nèi)外觸發(fā)器選擇，閃光延遲，分配器和慢動(dòng)作模式。

The QB-LED uses the "strobe effect" whereby when the flash rate is equal to the rotational speed, the target will appear "frozen". Typical applications include: motion and vibration analysis, balancing of rotating shafts, fans, cams, high speed motion analysis of speakers or ink-jet printing and more. Ideal for use in the textile, paper making, sheet metal production, automotive and printing industries.

QB-LED運(yùn)用了閃光效應(yīng)，當(dāng)閃光頻率等同于旋轉(zhuǎn)速度時(shí)，被測(cè)物呈現(xiàn)出凍結(jié)狀態(tài)。經(jīng)典應(yīng)用有：運(yùn)動(dòng)與振動(dòng)分析，轉(zhuǎn)軸平衡，風(fēng)扇，相機(jī)，揚(yáng)聲器和噴墨式打印機(jī)的高速移動(dòng)分析。是紡織行業(yè)，造紙行業(yè)，鈑金生產(chǎn)加工，汽車(chē)和印刷行業(yè)的理想之選。
