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 DT-361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,越來越多的行業(yè)開始使用頻閃儀來幫助解決產(chǎn)品質(zhì)量檢驗(yàn)問題。

Check-Line DT-361 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。

The Checkline DT-361 High-Intensity LED Stroboscope is designed to measure rotational and reciprocating speed and is ideal for machinery process inspection. The DT-361 Stroboscope is capable of flashing its LED lights in a synchronous frequency to the operating machinery, creating the illusion of viewing slowed or frozen images. Utilizing this phenomenon of slowing or stopping the motion with the adjusted flash rate of its LED lights, machine parts and processes may be inspected for defects, aiding in preventative maintenance programs. The Check-Line DT-361's LED technology extends operation due to the low energy requirement of the light diodes compared with xenon stroboscopes. Maintenance time and down time is reduced since there is no need to replace the bulb typical of xenon lit stroboscopes. The light output (Lux) of the LED array is far brighter than not only xenon powered stroboscopes, but all comparable LED stroboscopes on the market.
