產(chǎn)品介紹Product introduction：

DQL系列測(cè)量光幕使用同步掃描來(lái)識(shí)別被擋的通道。首先一個(gè)發(fā)射器通過(guò)發(fā)出光脈沖而對(duì)應(yīng)的接收器同時(shí)來(lái)尋找該脈沖，當(dāng)找到后即完成一個(gè)通道的掃描，接著轉(zhuǎn)向下一個(gè)通道，直到所有的掃描都完成。當(dāng)一個(gè)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(gè)信號(hào)，該信號(hào)可以是模擬量信號(hào)、開(kāi)關(guān)量信號(hào)、也可以是RS485通訊信號(hào)。

高精度的DQL系列測(cè)量光幕適用于高精度的檢測(cè)和測(cè)量。包括在線檢測(cè)、尺寸測(cè)量、輪廓檢測(cè)、精度糾偏、孔洞檢測(cè)、外形檢測(cè)、邊緣和中心定位，張力控制，零件計(jì)數(shù)、在線產(chǎn)品尺寸檢測(cè)和以上類(lèi)似的檢測(cè)和測(cè)量。每套系統(tǒng)包括一對(duì)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 location, 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.
