壓力傳感器與液位傳感器是我們經(jīng)常使用的兩款傳感器，但是很少有人知道他們直接有什么與區(qū)別。只有了解壓力傳感器和液位傳感器的區(qū)別才能更好的選擇自己需要的類型。
首先，壓力傳感器和液位傳感器的測量原理是相似的，都是利用當傳感器投入到被測液體中某一深度時，傳感器迎液面受到的壓力公式為：Ρ=ρ.g.H + Po式中：P是液位計迎液面所受壓力 ρ是被測液體密度g是重力加速度（調(diào)試時按照9.8015） Po是液面上大氣壓H是傳感器投入液體的深度同時，通過導(dǎo)氣不銹鋼將液體的壓力引入到傳感器的正壓腔，再將液面上的大氣壓Po與傳感器的負壓腔相連，以抵消傳感器背面的Po，使傳感器測得壓力為：ρ.g.H，顯然,通過測取壓力P，可以得到液位深。只是壓力傳感器輸出是是壓力P，而液位傳感器輸出的是深度H。
其次，壓力傳感器與液位傳感器的分類不同。壓力傳感器一般可分為應(yīng)變片壓力傳感器、陶瓷壓力傳感器、擴散硅壓力傳感器、藍寶石壓力傳感器、壓電壓力傳感器。而液位傳感器一般分為浮球式液位變送器、浮筒式液位變送器、靜壓式液位變送器。
zui后，液位傳感器可以說是壓力傳感器功能的拓展。在很多情況下只要稍作改變，液位傳感器和壓力傳感器就可以通用。隨著技術(shù)的發(fā)展，以及使用環(huán)境的變化，壓力傳感器和液位傳感器的分工也會越來越詳細。它們也將各盡所能。從而使壓力傳感器和液位傳感器變成兩個不同的大家族。
