“美国压电PCB 表面传声器130B40”详细介绍
表面传声器130B40
简介：130B40是一款防水防尘的预极化（0V）测量传声器，它由ICP®或等效恒流源供电，10-32微点式接头。130B40传声器的一个关键特征是最大动态范围可以达到142dB (3%失真)。 它的灵敏度为8.5mV/Pa，噪声值在32dBA。它支持TEDS 1.0，可以存储有用的校准和厂家数据。应用：130B40的典型应用包括空间受限的腔体声压级测试、环境测试、晴空湍流（CAT）、龙卷风研究、风洞测试及其它的关注风噪的常规噪声分析。表面传声器可以用于冲刷安装应用，也可以安装到墙里，或者可以粘结安装到一个平面上。它的高度只有1/8英寸（3mm），非常适合于需要低轮廓传声器测试的场合。
