</p> <p> 壓力變送器的噪聲分為內(nèi)噪聲與外噪聲，其中內(nèi)噪聲又包括熱噪聲和散粒噪聲。什么是壓力變送器的噪聲，這對(duì)我們的現(xiàn)場使用又有什么影響，我們要怎樣進(jìn)行壓力變送器的降噪呢？ </p> <p> 熱噪聲:熱噪聲主要來源于壓力變送器自身，這種噪聲是不能被根除的，只能使用阻值小的電阻進(jìn)行配合使用，以此來降低熱噪聲的大小。還有，需注意的一點(diǎn)就是，壓力變送器的熱噪聲與頻帶寬這一要素有著密切聯(lián)系。因此，在壓力變送器熱噪聲的降低中，還可選擇窄頻帶放大器的方法。 </p> <p> 散粒噪聲:這一噪聲產(chǎn)生的原理在于帶電粒子在電極上引起電容效應(yīng)的過程。電容效應(yīng)包括電容放電和電流噪聲兩種情況，為了降低壓力變送器的散粒噪聲，可以使用窄頻帶的放大器。 </p> <p> 外噪聲:壓力變送器外噪聲指的是自然干擾或人為干擾形成的噪聲，外噪聲的來源主要包括雷電、電氣等等。同時(shí)，當(dāng)壓力變送器帶有公共電源時(shí)，電流的頻繁變化就會(huì)引起噪聲的產(chǎn)生，河北煙塵治理壓力變送器推薦廠家。對(duì)于人為因素引起的壓力變送器噪聲，我們可以對(duì)這些變量進(jìn)行控制，河北煙塵治理壓力變送器推薦廠家，但對(duì)于那些自然現(xiàn)象引起的外在噪聲，則是無法避免的。 </p> <p> 壓力變送器的噪聲會(huì)降低變送器的分辨率及測量精度，還會(huì)對(duì)控制系統(tǒng)產(chǎn)生影響。在壓力變送器的使用過程中需要多加注意。壓力變送器根據(jù)傳感器種類，河北煙塵治理壓力變送器推薦廠家，可分為電容式壓力變送器、擴(kuò)散硅壓力變送器、單晶硅壓力變送器。河北煙塵治理壓力變送器推薦廠家</p><div

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(duì)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(duì)壓力變送器進(jìn)行操作。常規(guī)的壓力變送器輸出信號(hào)有4～20mA電流輸出、0～10VDC、0.5～2.5VDC等電壓輸出和RS485數(shù)字輸出信號(hào)。</p><div

防爆型壓力變送器介紹： </p> <p> 防爆型壓力變送器是通過被測的氣體或者液體的施壓，使得防爆壓力變送器的電阻值發(fā)生變化（電阻效應(yīng)），將測量的相對(duì)應(yīng)的信號(hào)轉(zhuǎn)化成相對(duì)應(yīng)的4~20mA輸出信號(hào)或者帶HART協(xié)議的數(shù)字信號(hào)以進(jìn)行通訊。防爆型壓力變送器安全防爆，可廣泛應(yīng)用于石化、電力、冶金、制藥、食品加工等行業(yè)。 </p> <p> 防爆型壓力變送器應(yīng)用的爆炸性危險(xiǎn)場所可分為0區(qū)、1區(qū)和2區(qū)。所謂0區(qū)是指在正常情況下，爆炸性氣體混合物連續(xù)的或長時(shí)間地存在的場所；1區(qū)是指在正常情況下，爆炸性氣體混合物有可能出現(xiàn)的場所，2區(qū)指的是在正常情況下，爆炸性氣體不可能出現(xiàn)或即使出現(xiàn)也只是短暫時(shí)間存在的場所。對(duì)于防爆型壓力變送器來說，對(duì)0區(qū)的防爆要求是為嚴(yán)格的。壓力變送器可以是本安型、隔爆型，需要注意的是，不管什么形式的防爆型壓力變送器，均需要有國家防爆檢測部門的核實(shí)、取得相關(guān)防爆證書方可使用。 </p> <p> 防爆型壓力變送器中本安型需要配合安全柵才能在有爆炸性混合物的危險(xiǎn)場所使用。安全柵是靠控制能量來達(dá)到防爆規(guī)定的。本質(zhì)安全型防爆壓力變送器為了安全起見，應(yīng)區(qū)別本質(zhì)安全回路及非本質(zhì)安全回路，把本質(zhì)安全回路的接線與其它的電氣回路的接線分開走線。河北煙塵治理壓力變送器推薦廠家</p><p
