德國(guó)P+F漫反射式超聲波傳感器簡(jiǎn)單介紹

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.
大多數(shù)的漫反射模式傳感器可以通過(guò)軟件參數(shù)設(shè)置，轉(zhuǎn)換為反射板模式。
有的超聲波傳感器從開(kāi)始就提供了反射板模式的傳感器。
這種類型的超聲波傳感器的反射器和接收器在同個(gè)外殼里面。
單個(gè)的超聲波換能器在發(fā)射和接收模式下循環(huán)的切換。
目標(biāo)物體相當(dāng)于聲波的反射體。
產(chǎn)品特點(diǎn)：
檢測(cè)范圍取決于目標(biāo)物的反射特性，
即被測(cè)物體的表面特性和入射角度會(huì)影響傳感器的檢測(cè)范圍。
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.
超聲波傳感器zui常用的模式是漫反射模式。
在有限范圍內(nèi)可以通過(guò)調(diào)節(jié)靈敏度來(lái)補(bǔ)償以上影響。
僅有個(gè)部件，安裝費(fèi)用低
對(duì)物體的反射特性比較敏感
 To prevent any cross-talk between the signals of the individual sensors,
the UC2000-L2 devices operate in automatic multiplex mode.
單個(gè)超聲波傳感器既是發(fā)射器又是接收器，
并且通常包含相應(yīng)的電子處理元件在同個(gè)外殼內(nèi)。
用于發(fā)射和接收聲波的換能器是分開(kāi)的，

這樣系統(tǒng)就無(wú)需等待發(fā)射器的信號(hào)衰減，
從而的減小了盲區(qū)。
直接檢測(cè)型的超聲波傳感器有開(kāi)關(guān)量和模擬量輸出。
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, 外殼: 黃銅鍍鎳,
為了地檢測(cè)困難目標(biāo)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檢測(cè)型傳感器
都可作為反射板型傳感器使用（見(jiàn)反射板型傳感器）。
單頭系統(tǒng), 窄的發(fā)射聲錐,
開(kāi)關(guān)輸出, 小的盲區(qū),
雙頭系統(tǒng)
連接類型: 連接器 M12 x 1 , 4 針
To determine the exact size of packages, a sensor has to evaluate it reliably and precisely.
Reflective surfaces and color can affect the measurement.
