德国P+F漫反射式超声波传感器简单介绍

Packages that are wrapped in reflective film and packages
 that are just a few centimeters wide, must be measured with precision.
SIPI Parcelscan features integrated scales to calculate the weight of the goods,
while the length of the outer surfaces is determined by ultrasound.
大多数的漫反射模式传感器可以通过软件参数设置，转换为反射板模式。
有的超声波传感器从开始就提供了反射板模式的传感器。
这种类型的超声波传感器的反射器和接收器在同个外壳里面。
单个的超声波换能器在发射和接收模式下循环的切换。
目标物体相当于声波的反射体。
产品特点：
检测范围取决于目标物的反射特性，
即被测物体的表面特性和入射角度会影响传感器的检测范围。
The ultrasonic sensors have a range of two meters and detect the outer dimensions of the boxes with millimeter precision.
The narrow acoustic beam angle allows the sensors to be positioned close to the table’s edges.
超声波传感器zui常用的模式是漫反射模式。
在有限范围内可以通过调节灵敏度来补偿以上影响。
仅有个部件，安装费用低
对物体的反射特性比较敏感
 To prevent any cross-talk between the signals of the individual sensors,
the UC2000-L2 devices operate in automatic multiplex mode.
单个超声波传感器既是发射器又是接收器，
并且通常包含相应的电子处理元件在同个外壳内。
用于发射和接收声波的换能器是分开的，

这样系统就无需等待发射器的信号衰减，
从而的减小了盲区。
直接检测型的超声波传感器有开关量和模拟量输出。
In this process, the packages are positioned on the table in a corner that is bordered by end strips on two sides.
 Pepperl+Fuchs UC2000-L2 series ultrasonic sensors are mounted at ends of strips and record the packages’ length and width.
The height is detected by an additional sensor positioned above the table.
系列: -12GM, 外壳: 黄铜镀镍,
为了地检测困难目标物，
This means that small packages with an overall length of just a few centimeters can also be measured.
Positioning the sensors close to the outer edges ensures that the table can be easily loaded and unloaded.
所有支持窗口模式功能的直接检测型传感器
都可作为反射板型传感器使用（见反射板型传感器）。
单头系统, 窄的发射声锥,
开关输出, 小的盲区,
双头系统
连接类型: 连接器 M12 x 1 , 4 针
To determine the exact size of packages, a sensor has to evaluate it reliably and precisely.
Reflective surfaces and color can affect the measurement.
