什麼是頻閃儀以及如何使用頻閃儀？

頻閃儀是一種轉動設備診斷檢查工具，用於閃爍高強度光以在運動部件上產生定格效果。主要目的是測量電機或風扇在 300 轉/分鍾 (RPM) 或以上運行時的轉速 (RPM)。人眼不會解釋定格動畫效果低於 300 轉/分。要測量電機的轉速 (RPM)，頻閃儀必須能夠看到零件表麵的完整 360° 旋xuan轉zhuan。零ling件jian應ying該gai有you某mou種zhong標biao記ji，可ke以yi用yong作zuo旋xuan轉zhuan麵mian上shang的de參can考kao點dian。通tong常chang，放fang置zhi在zai風feng扇shan主zhu軸zhou或huo電dian機ji軸zhou上shang的de標biao簽qian或huo點dian會hui起qi作zuo用yong。假jia設she頻pin閃shan儀yi能neng夠gou在zai產chan品pin的de旋xuan轉zhuan速su度du範fan圍wei內nei閃shan爍shuo，稱cheng為wei閃shan光guang頻pin率lv，您nin將jiang調tiao整zheng頻pin閃shan儀yi以yi通tong過guo停ting止zhi運yun動dong使shi參can考kao點dian可ke見jian。閃shan光guang頻pin率lv以yi每mei分fen鍾zhong閃shan光guang數shu (FPM) 為單位測量。 FPM 相當於 RPM。 4X 真實轉速的 FPM 將產生 4 個參考點。 3X 的 FPM 產生 3，而 2X 隻產生兩個。通過從zui大設置向下調整閃光速率
，參考點zui終將顯示為單個可視對象。一旦您隻看到一個固定參考點
，頻閃儀就會設置為產品的真實轉速 (RPM)。為了確認，將閃光頻率除以二。您仍將看到單個圖像，但該圖像會出現相位或沿相反方向緩慢旋轉。

轉速和頻閃的名詞解釋：

RPM:Rotational per minute,rpm就是每分鍾轉動多少次。

轉速(Rotational Speed或Rev)是做圓周運動的物體單位時間內沿圓周繞圓心轉過的圈數（與頻率不同）。

轉速的標準單位為rps （轉/秒）或 rpm （轉/分），也有表示為RPM (轉/分 ，主要為日本和歐洲采用
，我國采用標準)。

FPM= flashes per minute,FPM就是每分鍾閃爍次數
，FPM相當於RPM.

What is a stroboscope and how to use one?

Stroboscopes are diagnostic inspection tools used to flash a high intensity light to create a stop motion effect on a moving part. The primary purpose is to measure the rotational speed (RPM) of a motor or fan when in operation at or above 300 revolutions per minute (RPM). The human eye won’t interpret a stop motion effect below 300 RPM.

To measure the rotational speed (RPM) of a motor, the stroboscope must be able to see the full 360° rotation of a face on the part. The part should have some sort of marking that can be used as a reference point on the rotational face. Often a label or dot placed on the spindle of a fan or shaft of a motor will work. Assuming the stroboscope is capable of flashing within the range of the rotational speed of the product, known as the flash rate, you will be to adjust the stroboscope to make the reference point visible through stop motion. The flash rate is measured in flashes per minute (FPM). FPM is the equivalent to RPM. A FPM of 4X the true rotational speed will produce 4 reference points. A FPM of 3X produces 3 and 2X only two. By adjusting the flash rate down from the maximum setting, the reference point will eventually appear as a single viewable object. Once you see just one stationary reference point, the stroboscope is set to the true rotational speed (RPM) of the product. To confirm, divide the flash rate in half. You will still see a single image but the image will appear to phase or spin slow in the opposite direction.

LUYOR-905 stroboscope is a hand-held LED stroboscope. Its compact 4.9” X 2.8” X 1.3” size and battery  operation makes it very portable. A six button membrane allows for easy and accurate flash rate and flash phase adjustments. The LabStrobe flash rate range is 20 to 20,000 FPM. The innovative microprocessor design and LUXEON LED technology incorporated into the LUYOR-905 LED Stroboscope provides this pocket sized strobe with unparalleled brightness and battery life at this price point. An optional tripod is available. LUYOR-905 can be ordered directly from our website at  http://butiela.cn/pinshanyi/LUYOR-905.html     (RMB4800.00 ea. – available now).
