德國BERNSTEIN液位傳感器工作原理上海維特銳,BERNSTEIN液位傳感器工作原理
用靜壓測量原理:當液位 變送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 :變送器迎液面所受壓力
ρ:被測液體密度
g :當地重力加速度
Po :液面上大氣壓
H :變送器投入液體的深度
同時,通過導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 ,可以得到液位深度。

德國BERNSTEIN液位傳感器工作原理上海維特銳,德國BERNSTEIN液位傳感器是一種常見的測量液位位置的傳感器,它是將位的高度轉化為電信號的形式進行輸出。近年來,隨著電子技術和自動化的不斷發展,液位測量與控制技術有很大的提高。日化品、食品飲料、醫藥等行業的生產,都離不開液位的監控,BERNSTEIN液位傳感器的重要性日趨凸顯,甚至直接影響著產品的質量。接下來皮卡中國小編將跟大家說聊聊液位傳感器。
BERNSTEIN液位傳感器定義:
BERNSTEIN液位傳感器是一種測量液位的壓力傳感器。它分為接觸式和非接觸式。
BERNSTEIN液位傳感器的類型:
1、浮球式液位傳感器
由行業產品磁性浮球、測量導管、信號單元、電子單元、接線盒及安裝件組成。一般磁性浮球的比重小于0.5,可漂于液面之 上并沿測量導管上下移動。導管內裝有測量元件,它可以在外磁作用下將被測液位信號轉換成正比于液位變化的電阻信號,并將電子單元轉換成4~20ma或其它 電子商務標準信號輸出。
2、浮筒式液位傳感器
是將磁性浮球改為浮筒,浮筒式液位傳感器是利用微小的金屬膜應變傳感技術來測量液體的液位、界位或密度的。原文地址:
3、靜壓式液位傳感器
是利用防爆流量計液體靜壓力的測量原理工作。一般選用硅壓力測壓傳感器將測量到的壓力轉換成電信號,之后再經放大電路放大和補償電路補償,zui后以4~20ma或0~10ma電流方式輸出。
