DQL測量、檢測光幕：
產(chǎn)品介紹Product introduction：
DQL系列測量光幕使用同步掃描來識別被擋的通道。首先一個發(fā)射器通過發(fā)出光脈沖而對應(yīng)的接收器同時來尋找該脈沖，當找到后即完成一個通道的掃描，接著轉(zhuǎn)向下一個通道，直到所有的掃描都完成。當一個周期掃描完成后，系統(tǒng)記錄哪些通道通光，哪些通道被遮擋，根據(jù)系統(tǒng)定義輸出一個信號，該信號可以是模擬量信號、開關(guān)量信號、也可以是RS485通訊信號。
高精度的DQL系列測量光幕適用于高精度的檢測和測量。包括在線檢測、尺寸測量、輪廓檢測、精度糾偏、孔洞檢測、外形檢測、邊緣和中心定位，張力控制，零件計數(shù)、在線產(chǎn)品尺寸檢測和以上類似的檢測和測量。每套系統(tǒng)包括一對高分辨率的發(fā)射器和接收器、兩條電纜。
Measurement using DQL series synchronous scanning to identify the blocked channel. First, a transmitter sends a light pulse corresponding to the receiver to look for the pulse at the same time. When it is found, it completes a scan of the channel, then turns to the next channel until all the scans have been completed. When a scan cycle is completed, the system records which channel through which light channel is blocked, the output signal according to the system definition, the signal can be analog signals and digital signals, can also be a RS485 communication signal.
The detection and measurement of DQL series high precision measurement for high accuracy. Including online detection, measurement, contour detection, precision, deviation detection, contour detection, hole edge and center b, tension control, parts counting, online product size detection and similar detection and measurement. Each system consists of a pair of high resolution transmitters and receivers, and two cables.
