頻閃儀是指控制光源發(fā)光，以特定頻率快速閃動的光學(xué)測量儀器。美國Checkline DT-365頻閃儀本身可以發(fā)出短暫又頻密的閃光,當(dāng)調(diào)節(jié)頻閃燈的閃動頻率,使其與被測物的轉(zhuǎn)動或運動速度接近或同步時,被測物雖然高速運動著,但看上去卻是緩慢運動或相對靜止,這種視覺暫留現(xiàn)象使人目測就能輕易觀測到高速運動物體的表面質(zhì)量與運行狀況 ,而頻閃儀的閃光速度即為被檢測物體(例如:馬達(dá) )轉(zhuǎn)速和運動頻率 (印刷袋 ) ,亦可以利用頻閃儀分析物體振動情況、 高速移動物體的動作以及高速攝影等。利用頻閃儀觀測檢驗技術(shù)在歐美已廣泛使用 ,隨著我國經(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)量檢驗問題。

Check-Line DT-365 頻閃儀也叫頻閃靜像儀或轉(zhuǎn)速計 ,是能夠使作振動、 高速旋轉(zhuǎn)或周期運動構(gòu)件變成“ 靜止不動 " 構(gòu)件的一種光學(xué)測量裝置。

High-Intensity, Battery Powered LED Stroboscopes. The Checkline DT-365 and Check-Line DT-365E High-Intensity, Battery Powered LED Stroboscopes are velocity analyzing and measuring devices that are ideal for machinery process inspection. The DT-365 and DT-365E Stroboscopes are capable of flashing their 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. This LED technology extends operation due to the low energy requirement of the light diodes compared with xenon lit stroboscopes. Proper operation is assured as concern of light failure during usage, common with xenon bulbs, is eliminated. The light output (Lux) of the LED’s is far brighter than xenon powered stroboscopes with the DT-365 outshining all comparable stroboscopes on the market from its array of 18 LED’s and 6 LED’s for the DT-365E.
