ELA（Electro-L liquid level or pressure）壓力傳感器是一種專門用于測(cè)量液位或壓力的電子設(shè)備，它屬于工業(yè)過程控制和自動(dòng)化領(lǐng)域中的重要組成部分。這種傳感器通常采用電容式、壓阻式或 piezoelectric (壓電) 原理來感知環(huán)境中的壓力變化，當(dāng)被測(cè)介質(zhì)的壓力作用于傳感器的敏感元件時(shí)，如膜片或應(yīng)變計(jì)，會(huì)產(chǎn)生相應(yīng)的電信號(hào)變化。 具體來說，對(duì)于液位測(cè)量，ELA壓力傳感器通過感受液面高度對(duì)膜片產(chǎn)生的浮力或靜壓差，轉(zhuǎn)換為與之成比例的電信號(hào)輸出；而對(duì)于壓力測(cè)量，則是直接感應(yīng)壓力導(dǎo)致的彈性元件形變量，將其轉(zhuǎn)化為電壓、電流或其他形式的可讀信號(hào)。這些信號(hào)經(jīng)后續(xù)的信號(hào)調(diào)理和放大電路處理后，可以實(shí)時(shí)傳輸給控制器或者數(shù)據(jù)采集系統(tǒng)，從而實(shí)現(xiàn)對(duì)生產(chǎn)過程中的壓力或液位參數(shù)進(jìn)行精確監(jiān)控與控制。廣泛應(yīng)用于石油、化工、水處理、食品飲料、制藥等行業(yè)的自動(dòng)化控制系統(tǒng)中。
