德國Sensoren超聲波傳感器
德國Sensoren超聲波傳感器 超聲波傳感器使用高頻聲波脈沖作為測量媒介質(zhì)，當(dāng)聲波遇到介質(zhì)就會被反射回來，通過測量從發(fā)送到接收到的時間差來計(jì)算物體到傳感器的距離。超聲波傳感器主要應(yīng)用于傳統(tǒng)光學(xué)傳感器不能測量的場合，例如， 透明物體或液體。另一典型的應(yīng)用是 物位測量，例如對遠(yuǎn)距離的散裝貨物。

超聲波傳感器可能是一種有用的替代方案，其中光學(xué)傳感器抵抗其物理極限。 這適用于例如具有不平坦表面或在困難的環(huán)境條件下的物體，或者具有高度透明的介質(zhì)以及移動的高反射性液體表面。
因此，超聲波傳感器的典型用途是檢查高度透明箔的存在并測量液體容器中的填充水平。 超聲波傳感器的主要優(yōu)點(diǎn)是由它們的聲音飛行時間測量原理產(chǎn)生的可靠的背景抑制。

Typical Ultrasonic sensors 
| Ultrasonic sensors may be a useful alternative where optical sensors come up against their physical limits. This applies, for example, for objects with uneven surfaces or under difficult ambient conditions, or with highly transparent media as well as moving,highly reflective liquid surfaces. Typical uses of ultrasonic sensors are therefore checking the presence of highly transparent foils and measuring the filling levels in liquid containers. A major advantage of ultrasonic sensors is the absoluy reliable background suppression resulting from their sound time-of-flightmeasurement principle. Learn more about the ultrasonic sensors
