頻閃儀是指控制光源發(fā)光，以特定頻率快速閃動的光學測量儀器。美國Checkline QBS-LED頻閃儀本身可以發(fā)出短暫又頻密的閃光,當調(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 )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在歐美已廣泛使用 ,隨著我國經(jīng)濟的高速發(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 QBS-LED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)或周期運動構件變成“ 靜止不動 " 構件的一種光學測量裝置。
Flash range of 30 - 300,000 fpm (0.5-5000 Hz)
The Check-Line QBS-LED is a hand-held, battery-powered stroboscope featuring 118 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.
The Checkline QBS-LED features a robust aluminum housing fitted with forty long-life, high performance LEDs providing a peak brightness of 10,000 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.
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.
The QBS-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.
Built-In Laser Light Source provides a Non-Contact "Tachometer Mode" when used in combination with reflective tape. It also features a unique "Auto-Sync" feature using the Laser Tachometer Mode to automatically set the correct flash rate to instantly "freeze" the rotating target without requiring any adjustment by the end-user. It also features a "Slow Motion" Mode that allows the user to offset the flash rate to put the "frozen" image into virtual "slow-motion".
