产品介绍Product introduction：

DQL系列测量光幕使用同步扫描来识别被挡的通道。首先一个发射器通过发出光脉冲而对应的接收器同时来寻找该脉冲，当找到后即完成一个通道的扫描，接着转向下一个通道，直到所有的扫描都完成。当一个周期扫描完成后，系统记录哪些通道通光，哪些通道被遮挡，根据系统定义输出一个信号，该信号可以是模拟量信号、开关量信号、也可以是RS485通讯信号。

高精度的DQL系列测量光幕适用于高精度的检测和测量。包括在线检测、尺寸测量、轮廓检测、精度纠偏、孔洞检测、外形检测、边缘和中心定位，张力控制，零件计数、在线产品尺寸检测和以上类似的检测和测量。每套系统包括一对高分辨率的发射器和接收器、两条电缆。

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.
