5、壓電壓力傳感器原理與應(yīng)用 </p> <p> 壓電傳感器中主要使用的壓電材料包括有石英、酒石酸鉀鈉和磷酸二氫胺。其中石英（二氧化硅）是一種天然晶體，壓電效應(yīng)就是在這種晶體中發(fā)現(xiàn)的，在一定的溫度范圍之內(nèi)，壓電性質(zhì)一直存在，但溫度超過這個范圍之后，壓電性質(zhì)完全消失（這個高溫就是所謂的“居里點(diǎn)”）。由于隨著應(yīng)力的變化電場變化微?。ㄒ簿驼f壓電系數(shù)比較低），所以石英逐漸被其他的壓電晶體所替代。而酒石酸鉀鈉具有很大的壓電靈敏度和壓電系數(shù)，但是它只能在室溫和濕度比較低的環(huán)境下才能夠應(yīng)用。磷酸二氫胺屬于人造晶體，能夠承受高溫和相當(dāng)高的濕度，所以已經(jīng)得到了***的應(yīng)用。上海直銷轉(zhuǎn)速變送器</p><p
