超声波传感器基本介绍

超声波传感器是利用超声波的特性研制而成的传感器。以超声波作为检测手段，必须产生超声波和接收超声波。完成这种功能的装置就是超声波传感器，习惯上称为超声换能器，或者超声探头。

超声波探头主要由压电晶片组成，既可以发射超声波，也可以接收超声波。超声探头的核心是其塑料外套或者金属外套中的一

块压电晶片。构成晶片的材料可以有许多种。超声波传感器主要材料有压电晶体（电致伸缩）及镍铁铝合金（磁致伸缩）两类。电致伸缩的材料有锆钛酸铅（PZT）等。压电晶体组成的超声波传感器是一种可逆传感器，它可以将电能转变成机械振荡而产生超声波，同时它接收到超声波时，也能转变成电能，所以它可以分成发送器或接收器。有的超声波传感器既作发送，也能作接收。超声波传感器由发送传感器（或称波发送器）、接收传感器（或称波接收器）、控制部分与电源部分组成。发送器传感器由发送器与使用直径为15mm左右的陶瓷振子换能器组成，换能器作用是将陶瓷振子的电振动能量转换成超能量并向空中幅射；而接收传感器由陶瓷振子换能器与放大电路组成，换能器接收波产生机械振动，将其变换成电能量，作为传感器接收器的输出，从而对发送的超声波进行检测。控制部分主要对发送器发出的脉冲链频率、占空比及稀疏调制和计数及探测距离等进行控制。
