超声波传感器（检测距离远，不受目标物透光性及颜色的影响）：

l  极强的抗干扰能力/Strong anti-interference ability

l  漫反射式盲区只有10mm! 行业最小盲区，使得更多应用成为可能，比如pcb设备。/Blind zone only 10mm,enable more applications, such as pcb devices

l  可以稳定检测纸张，木片，塑料板，薄金属板等的单双张/ Can stably detect if paper, wood sheet, plastic sheet, thin metal sheet double, etc

l  可以安装在容器底部测量液位高度，串口/模拟量输出/ installed at the bottom of the container to measure the level height, serial / analog output

l  分辨率高，重复精度高/ high resolution &high repeatablity

l  可抑制高压气枪的干扰/anti-disturb of compressed air

l  开关量，模拟量，串口输出/digital, analog, serial port output
