src="https://tyunfile.71360.com/UploadFile/xalunqian/637328439170791016/8261680.png"></div><p> 壓力變送器與液位傳感器是各類設(shè)備中或項(xiàng)目中經(jīng)常遇到的兩類傳感器，下面來了解壓力變送器與液位傳感器兩者的區(qū)別? </p> <p> 1、壓力傳感器和液位傳感器的測量原理，都是將傳感器投入被測液體設(shè)定深度，傳感器測量點(diǎn)直接接觸液面受到的壓力公式為：Ρ=ρ.g.H + Po,式中：P表示液位傳感器測量點(diǎn)直接接觸液面所受壓力， ρ表示被測液體的密度值，g表示重力加速度,Po是液面上大氣壓,H是傳感器投入液體的深度同時(shí)，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(fù)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。 </p> <p> 2、液位測量法：液位測量方法可分為機(jī)械高度法和壓強(qiáng)測定法。機(jī)械高度：機(jī)械傳動(dòng)結(jié)構(gòu)復(fù)雜，器械的豎直度影響測量精度。并且是筆繪模擬曲線或人工讀數(shù)。壓強(qiáng)法：利用埋于液體底部或一定深度的壓力傳感器測定壓力，利用公式Pa=ρCH得到液位的高度。又可根據(jù)容器的結(jié)構(gòu)設(shè)計(jì)尺寸得到相應(yīng)高度的容器容量——所盛液體的體積。壓力傳感器輸出的是與壓力傳感器成正比的電信號，可以遠(yuǎn)距離傳輸，并便于自動(dòng)記錄和為處理器的修正、補(bǔ)償，進(jìn)一步提高精度。

溫度變從兩方面影響著壓力變送器的輸出，一是零點(diǎn)漂移，二是影響滿量程輸出。如：滿量程的+/-X%℃，讀數(shù)的+/-X%℃，在超出溫度范圍時(shí)滿量程的+/-X%，在溫度補(bǔ)償范圍內(nèi)時(shí)讀數(shù)的+/-X%，如果沒有這些參數(shù)，會導(dǎo)至在使用中的不確定性。壓力變送器輸出的變化到底是由壓力變化引起的，還是由溫度變化引起的。溫度因素是了解如何使用變送器時(shí)復(fù)雜的一部分。壓力變送器的各項(xiàng)基本參數(shù)是我們考量壓力變送器優(yōu)劣的重要綜合指標(biāo)。在實(shí)際應(yīng)用過程中，也需要對各項(xiàng)參數(shù)進(jìn)行嚴(yán)格把控。使得我們的工況安全有效的持續(xù)運(yùn)行。 </p> <p> <br /> </p> <p> <br /> </p><p> 壓力變送器過載能力意義 </p> <p> 在壓力變送器的眾多技術(shù)參數(shù)中，過載能力是一個(gè)重要參數(shù)指標(biāo)。我們怎樣理解壓力變送器的過載能力,這對壓力變送器的正常使用又有什么重要意義呢？接下來我們一起，一層層揭開這個(gè)神秘的面紗。 </p> <p> 過載:過載就是負(fù)荷過大，超過了設(shè)備本身的額定負(fù)載，產(chǎn)生的現(xiàn)象是電流過大，用電設(shè)備發(fā)熱，線路長期過載會降低線路絕緣水平，甚至燒毀壓力變送器設(shè)備或線路。 </p> <p> 過載能力:過載能力指的是壓力變送器超過額定限值以后能夠承受的能力范圍。在通信電源領(lǐng)域，設(shè)備有標(biāo)稱額定值標(biāo)示其所能承載的負(fù)荷，而設(shè)計(jì)時(shí)候往往會留有余量，該余量被稱為過載能力，通常用于描述UPS性能。 </p> <p> <br />
