德国SIEMENS西门子流量计7ML1025-1BD11
德国西门子SIEMENS超声波流量计常用压电换能器。它利用压电材料的压电效应,采用适出的发射电路把电能加到发射换能器的压电元件上,使其产生超声波振劝。超声波以某角度射入流体中传播,然后由接收换能器接收,并经压电元件变为电能,以便检测。发射换能器利用压电元件的逆压电效应,而接收换能器则是利用压电效应。
西门子超声波流量计换能器的压电元件常做成圆形薄片,沿厚度振动。薄片直径超过厚度的10倍,以保证振动的方向性。压电元件材料多采用锆钛酸铅。为固定压电元件,使超声波以合适的角度射入到流体中,需把元件故人声楔中,构成换能器整体(又称探头)。声楔的材料不仅要求强度高、耐老化,而且要求超声波经声楔后能量损失小即透射系数接近1。常用的声楔材料是有机玻璃,因为它透明,可以观察到声楔中压电元件的组装情况。另外,某些橡胶、塑料及胶木也可作声楔材料。
