遲滯：在規(guī)定的范圍內(nèi)，當(dāng)被測(cè)量值增加或減少時(shí)，輸出中出現(xiàn)的zuida差值。 </p> <p> 激勵(lì)：為使壓力變送器正常工作而施加的外部能量。一般是電壓或電流。施加的電壓或電流不同，壓力變送器的輸出值等參數(shù)也不同，所以有的參數(shù)，如零點(diǎn)輸出，上限值輸出、漂移等參數(shù)要在規(guī)定的激勵(lì)條件下測(cè)量。 </p> <p> 零點(diǎn)漂移：零點(diǎn)漂移是指在規(guī)定的時(shí)間間隔及標(biāo)準(zhǔn)條件下，零點(diǎn)輸出值的變化。由于周圍環(huán)境溫度變化引起的零點(diǎn)漂移稱為熱零點(diǎn)漂移。 </p> <p> 過(guò)載：通常是指能夠加在壓力變送器上不致引起性能長(zhǎng)久性變化的被測(cè)量的zuida值。 </p> <p> 穩(wěn) 定性：壓力變送器在規(guī)定的條件下儲(chǔ)存、試驗(yàn)或使用，經(jīng)歷規(guī)定的時(shí)間后，仍能保持原來(lái)特性參數(shù)的能力。 </p> <p> 可靠性：指壓力變送器在規(guī)定的條件下和規(guī)定的時(shí)間內(nèi)完成所需功能的能力。 </p> <p> 工作溫度：指壓力變送器能夠達(dá)到各項(xiàng)技術(shù)指標(biāo)和功能的環(huán)境溫度范圍。 </p> <p> 環(huán)境溫度：指壓力變送器在工作狀態(tài)下所處工作環(huán)境的溫度范圍。 </p><p> 壓力變送器過(guò)載能力意義 </p> <p> 在壓力變送器的眾多技術(shù)參數(shù)中，過(guò)載能力是一個(gè)重要參數(shù)指標(biāo)。我們?cè)鯓永斫鈮毫ψ兯推鞯倪^(guò)載能力,這對(duì)壓力變送器的正常使用又有什么重要意義呢？接下來(lái)我們一起，一層層揭開(kāi)這個(gè)神秘的面紗。 </p> <p> 過(guò)載:過(guò)載就是負(fù)荷過(guò)大，超過(guò)了設(shè)備本身的額定負(fù)載，產(chǎn)生的現(xiàn)象是電流過(guò)大，用電設(shè)備發(fā)熱，線路長(zhǎng)期過(guò)載會(huì)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(guò)載能力:過(guò)載能力指的是壓力變送器超過(guò)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(huì)留有余量，該余量被稱為過(guò)載能力，通常用于描述UPS性能。 </p> <p> <br />

以上這些因素我們的現(xiàn)場(chǎng)使用實(shí)際是什么樣的，就選擇相對(duì)應(yīng)的壓力變送器形式。這個(gè)是比較好選擇和控制的。用戶根據(jù)自己的現(xiàn)場(chǎng)進(jìn)行選擇就好。這就是我們對(duì)壓力變送器選用的第一步。做好這一步我們才能進(jìn)行接下來(lái)具體性能參數(shù)的選擇。如果被測(cè)量是多維向量，則要求變送器的交叉靈敏度越小越好。吉林無(wú)線遠(yuǎn)傳壓力變送器價(jià)格查詢</p><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(lái)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(cè)量原理，都是將傳感器投入被測(cè)液體設(shè)定深度，傳感器測(cè)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(cè)量點(diǎn)直接接觸液面所受壓力， ρ表示被測(cè)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(guò)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(cè)得壓力為：ρ.g.H，顯然,通過(guò)測(cè)取壓力P，可以得到液位深。 </p> <p> 2、液位測(cè)量法：液位測(cè)量方法可分為機(jī)械高度法和壓強(qiáng)測(cè)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(cè)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(cè)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(hào)，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。
