頻閃儀是指控制光源發光，以特定頻率快速閃動的光學測量儀器。美國Checkline DT-361頻閃儀本身可以發出短暫又頻密的閃光,當調節頻閃燈的閃動頻率,使其與被測物的轉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,這種視覺暫留現象使人目測就能輕易觀測到高速運動物體的表面質量與運行狀況 ,而頻閃儀的閃光速度即為被檢測物體(例如:馬達 )轉速和運動頻率 (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在歐美已廣泛使用 ,隨著我國經濟的高速發展,越來越多的行業開始使用頻閃儀來幫助解決產品質量檢驗問題。
Check-Line DT-361 頻閃儀也叫頻閃靜像儀或轉速計 ,是能夠使作振動、 高速旋轉或周期運動構件變成“ 靜止不動 " 構件的一種光學測量裝置。
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.
