SIEMENS西門子流量計7ML1034-2AA12

德國西門子SIEMENS超聲波流量計常用壓電換能器。它利用壓電材料的壓電效應(yīng)，采用適出的發(fā)射電路把電能加到發(fā)射換能器的壓電元件上，使其產(chǎn)生超聲波振勸。超聲波以某角度射入流體中傳播，然后由接收換能器接收，并經(jīng)壓電元件變?yōu)殡娔?，以便檢測。發(fā)射換能器利用壓電元件的逆壓電效應(yīng)，而接收換能器則是利用壓電效應(yīng)。
西門子超聲波流量計換能器的壓電元件常做成圓形薄片，沿厚度振動。薄片直徑超過厚度的10倍，以保證振動的方向性。壓電元件材料多采用鋯鈦酸鉛。為固定壓電元件，使超聲波以合適的角度射入到流體中，需把元件故人聲楔中，構(gòu)成換能器整體(又稱探頭)。聲楔的材料不僅要求強度高、耐老化，而且要求超聲波經(jīng)聲楔后能量損失小即透射系數(shù)接近1。常用的聲楔材料是有機玻璃，因為它透明，可以觀察到聲楔中壓電元件的組裝情況。另外，某些橡膠、塑料及膠木也可作聲楔材料。
