</p> <p> 壓力變送器剛買回來使用，效果很好，可沒幾天就不能用了。其實(shí)壓力變送器在使用過程中，如果方法不當(dāng)，是會造成損壞的。壓力變送器的損壞，會對用戶造成很大的影響。接下來教大家如何正確使用壓力變送器避免其損壞。希望能夠幫助到大家。 </p> <p> 1：在壓力傳輸過程中，應(yīng)注意壓力變送器與散熱管連接處，切勿漏氣。管路中必須保持暢通，管道中的沉積物，極有可能損壞壓力變送器膜片。開始使用前如果閥門是關(guān)閉的，則使用時(shí)應(yīng)該非常小心緩慢地打開閥門，以免被測介質(zhì)直接沖擊壓力變送器膜片從而損壞膜片。2：測量蒸汽或其他高溫介質(zhì)時(shí)，應(yīng)使用散熱管。溫度不得超過壓力變送器使用溫度的極限。3：切勿用硬物碰觸膜片，導(dǎo)致壓力變送器隔離膜片損壞。4：被測介質(zhì)不允許結(jié)冰，否則將損傷壓力變送器元件，導(dǎo)致變送器損壞，必要時(shí)需對壓力變送器進(jìn)行溫度保護(hù)，以防結(jié)冰。5：切勿用高于36V電壓加到壓力變送器上，導(dǎo)致變送器損壞。還有，在使用安裝壓力變送器前，一定要仔細(xì)認(rèn)真閱讀說明書。多方位了解壓力變送器的各項(xiàng)信息。保證在合理合規(guī)的前提下，對壓力變送器進(jìn)行操作。河北立柱式壓力變送器價(jià)格電流輸出是壓力變送器常用的一種信號輸出方式，這與它的性能特點(diǎn)有關(guān)。</p><div

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，并便于自動記錄和為處理器的修正、補(bǔ)償，進(jìn)一步提高精度。 </p> <p> <br /> </p><p> 壓力變送器是石化行業(yè)中使用的比較多的儀器儀表。在較為大型的石化項(xiàng)目中，應(yīng)用的壓力變送器型號更為廣，高溫型、防爆型、防水型、抗沖擊型以及各種材質(zhì)及特殊加工的壓力變送器。 </p> <p> 壓力變送器，可進(jìn)行表壓、絕壓和負(fù)壓的測量。具有精度高、穩(wěn)定性好、響應(yīng)速度快、抗干擾、耐沖等特點(diǎn)。膜片材質(zhì)采用316L不銹鋼，輸出信號可選擇電流型、電壓型和數(shù)字型輸出。對于石化行業(yè)來說，壓力變送器的精度是重要考量指標(biāo)，壓力變送器可定制0.1高精度產(chǎn)品。除了精度，壓力變送器的穩(wěn)定性也被控制在±0.1%FS/年。石化行業(yè)較為特殊，很多場合都需要用到防爆型壓力變送器。壓力變送器有隔爆型、本安型和粉塵本安型三種不同的防爆類型，客戶可根據(jù)現(xiàn)場實(shí)際使用情況進(jìn)行選擇。石化行業(yè)對壓力變送器的還有許多其它的要求，例如需要測量像原油這些帶有顆粒、沖擊大或者粘稠的介質(zhì)，這時(shí)就需要使用抗沖擊型壓力變送器，其特殊的工藝設(shè)計(jì)具有有效的抗干擾能力，測量的前端采用***、經(jīng)過特殊處理的堅(jiān)固膜片，精湛的力學(xué)傳遞結(jié)構(gòu)和封裝工藝使其具有結(jié)構(gòu)緊湊、抗震動、抗頻繁高壓沖擊、抗堅(jiān)固沙石沖擊、耐磨損等特點(diǎn)。是石化行業(yè)理想的壓力測量儀表。壓力變送器以其不錯(cuò)的性能和較為親民的價(jià)格，在市場上獲得了較高的占有率。</p><div

差壓變送器是有固定量程范圍的，在量程范圍內(nèi)使用，差壓變送器性能才是正常的。在現(xiàn)場使用過程中，如果出現(xiàn)超量程的現(xiàn)象。這時(shí)候要怎么對差壓變送器進(jìn)行排查呢？ </p> <p> 1、根據(jù)控制室趨勢圖進(jìn)行分析故障原因，排查是否因工藝原因造成的壓力值偏差，誤判斷為儀表問題。如果為工藝原因，趨勢指示與壓力示值程緩慢變化趨勢，或根據(jù)工況有規(guī)律變化，如果是儀表問題，一般趨勢圖不程緩慢變化，變化幅度非常劇烈。2、如處理故障為超量程，首先對其進(jìn)行斷電，而后在送電進(jìn)行觀察，如果故障顯示仍然為超量程，那么測量一下電流值是否對應(yīng)其指示壓力值。3、參照比較差壓變送器現(xiàn)場顯示壓力，與就地指示壓力表顯示的壓力值進(jìn)行比較，并確認(rèn)測量管道是否有余壓。4、對差壓變送器進(jìn)行一次到兩次機(jī)械零點(diǎn)調(diào)整，故障仍然顯示為超量程，那么就要考慮是否為儀表本身的故障。5、差壓變送器自身故障情況分為兩種。情況一：變送器3大模塊有故障，情況二：變送器感壓膜片變形。6、如果差壓變送器在更換模塊后故障仍為超量程，那么終情況即為差壓變送器感壓膜片變形或者損壞。擴(kuò)散硅壓力變送器可替代傳統(tǒng)的遠(yuǎn)傳壓力表，霍爾元件、差動變送器，并具有DDZ-Ⅱ及DDZ-Ⅲ型變送器性能。河北無線遠(yuǎn)傳壓力變送器怎么樣</p><p
