在連續(xù)7天24小時過程監(jiān)控應(yīng)用中，需要PLC，DCS或SCADA系統(tǒng)記錄、分析信號趨勢，具有4-20mA輸出信號的振動變送器是比較理想的選擇。但是4-20mA信號究竟表達什么呢？因為大多數(shù)振動變送器的基礎(chǔ)傳感元件跟典型的加速度計一樣或者相似，變送器將AC交流原始電壓信號在內(nèi)部轉(zhuǎn)化成電流信號。在轉(zhuǎn)化的過程中，電流輸出可能擴展為以下三個值中之一： </p> <p> RMS (root mean square) 有效值RMS（均方根值） </p> <p> AC信號轉(zhuǎn)換到DC信號并不是平均每個AC信號值那么簡單。對于正弦波，正半周期和負(fù)半周期是相等的，這個平均會產(chǎn)生零，沒有測量數(shù)值。相反，為了獲取有用的結(jié)果，對AC信號進行加權(quán)平均計算，術(shù)語稱為均方根值（RMS）。 </p> <p> Peak 峰值 </p> <p> True Peak 真實峰值 </p> <p> 一個4-20mA變送器轉(zhuǎn)換加速度電壓輸出到電流輸出，是通過多個電路過程來實現(xiàn)的。在AC到DC電壓轉(zhuǎn)換過程中，所有的頻率數(shù)據(jù)都從信號中消除。 </p> <p> <br /> </p> </p> <p> <br />

壓力傳感器被應(yīng)用于各行各業(yè)，尤其是工業(yè)上應(yīng)用非常多的壓力傳感器，但是工業(yè)上一般要求壓力傳感器能夠防腐蝕，壓力傳感器接頭和腔體采用進口不銹鋼整體加工，作為壓力變送器彈體的不銹鋼材料耐蝕性高、衰減性能好，可以監(jiān)測任何與316L相兼容的介質(zhì)。下面我們還來介紹一下壓力傳感器的防腐技巧。 </p> <p> 首先，了解被測介質(zhì)是否與316L相兼容：316，317L合金在100小時5%鹽霧測試中，都沒有出現(xiàn)腐蝕。其次，在選購傳感器產(chǎn)品時，向供應(yīng)商咨詢介質(zhì)對壓力傳感器是否有影響；通過對彈體耐腐蝕材料的選擇，以便達到用戶使用的需求。然后我們可以采用隔離辦法：壓力變送器前有鉬2鈦和鉭片，膜片與彈道管之間用甲基硅油傳送壓力，量程可做到0～100kPa，如果膜片材料還不耐腐，則可加一層F46膜片，但儀表靈敏度有所降低。也可直接用F46作隔離膜片，傳遞液可選用氟油，則可起雙重隔離作用。 </p> <p> 壓力傳感器在使用過程中一旦發(fā)現(xiàn)其不能與介質(zhì)兼容就必須馬上更換傳感器，對應(yīng)一些特殊的介質(zhì)我們可以采用特殊的材質(zhì)或者特殊的結(jié)構(gòu)來進行測量，壓力傳感器未來肯定會得到更加全方面的應(yīng)用，所以作為廠家我們要積極開發(fā)新型壓力傳感器來適應(yīng)需要。 </p> <p> <br /> </p><p> 稱重傳感器接線方法： </p> <p> 稱重傳感器的出線方式有4線和6線兩種，模塊或稱重變送器的接線也有4線和6線兩種，要接4線還是6線首先要看你的硬件要求是怎樣的，原則是：傳感器能接6線的不接4線，必須接4線的就要進行短接。 </p> <p> 一般的稱重傳感器都是六線制的，當(dāng)接成四線制時，電源線（EXC-，EXC+）與反饋線（SEN-，SEN+）就分別短接了。SEN+和SEN-是補償線路電阻用的。SEN+和EXC+是通路的，SEN-和EXC-是通路的。 </p> <p> EXC+和EXC-是給稱重傳感器供電的，但是由于稱重模塊和傳感器之間的線路損耗，實際上傳感器接收到的電壓會小于供電電壓。每個稱重傳感器都有一個mV/V的特性，它輸出的mV信號與接收到的電壓密切相關(guān)，SENS+和SENS-實際上是稱重傳感器內(nèi)的一個高阻抗回路，可以將稱重模塊實際接收到的電壓反饋給稱重模塊。假設(shè)EXC+和EXC-為10V,線路損耗，傳感器2mV/V，實際上傳感器輸出較大信號為（）*2=19mV，而不是20mV。此時稱重傳感器內(nèi)部就會把19mV作為較大量程，前提是傳感器必須通過反饋回路把實際電壓反饋給稱重模塊。在稱重傳感器上將EXC+與 SENS+短接，EXC-與SENS-短接，適合于傳感器與稱重模塊距離較近，電壓損耗非常小的場合，否則測量存在誤差。 </p> <p> <br /> 上海持承自動化設(shè)備有限公司主營稱重傳感器，如有合作需求，請留下您的聯(lián)系方式我們盡快回復(fù)您！</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="湖南PCB壓力傳感器選型資料,傳感器" src="https://tyunfile.71360.com/WaterMark/UploadFile/shchicheng/637439887974667689/1214626.jpg"></div><p> 壓力傳感器選用使用方法： </p> <p> 壓力傳感器是工業(yè)實踐中較為常用的一種傳感器。一般普通壓力傳感器的輸出為模擬信號，模擬信號是指信息參數(shù)在給定范圍內(nèi)表現(xiàn)為連續(xù)的信號。而我們通常使用的壓力傳感器主要是利用壓電效應(yīng)制造而成的，這樣的傳感器也稱為壓電傳感器。 </p> <p> 通常在選用的時候，需要具備以下幾點常識： </p> <p> 1、品牌誤區(qū)：很多時候大家都認(rèn)為國產(chǎn)的產(chǎn)品是不好用，甚至是不能用。 </p> <p> 2、精度誤區(qū)：大家在選擇產(chǎn)品的時候，總以為精度是較重要的；其實從某個角度來說：穩(wěn)定性比產(chǎn)品的精度更重要，精度選擇應(yīng)該是建立在高穩(wěn)定性的基礎(chǔ)上的。 </p> <p> 3、追求廉價：物美價廉這是每個人希望看到的；但事實上，***的產(chǎn)品就決定了它的價格會相對的高一些。 </p> <p> 4、選擇合適的量程、合適的精度、合適安裝方式、合適的輸出方式。 </p> <p> 在使用的時候也要對以下常識進行了解： </p> <p> 1、檢查安裝孔的尺寸、保持安裝孔的清潔； </p> <p> 2、正確安裝、選擇恰當(dāng)?shù)奈恢茫?</p> <p> 3、仔細(xì)清潔、保持干燥； </p> <p> 4、避免高低溫干擾、高低頻干擾、靜電干擾； </p> <p> 5、防止壓力過載； </p> <p> 壓力傳感器在我國的工業(yè)實踐中廣泛應(yīng)用于各種工業(yè)自控環(huán)境，涉及眾多行業(yè)，因此對其進行一個多方面的了解是非常有必要的。 </p> <p> <br />

多傳感器信息融合技術(shù)的基本原理就像人的大腦綜合處理信息的過程一樣，將各種傳感器進行多層次、多空間的信息互補和優(yōu)化組合處理，較終產(chǎn)生對觀測環(huán)境的一致性解釋。在這個過程中要充分地利用多源數(shù)據(jù)進行合理支配與使用，而信息融合的較終目標(biāo)則是基于各傳感器獲得的分離觀測信息，通過對信息多級別、多方面組合導(dǎo)出更多有用信息。這不僅是利用了多個傳感器相互協(xié)同操作的優(yōu)勢，而且也綜合處理了其它信息源的數(shù)據(jù)來提高整個傳感器系統(tǒng)的智能化。 </p> <p> 壓力傳感器是使用較為較廣的一種傳感器。傳統(tǒng)的壓力傳感器以機械結(jié)構(gòu)型的器件為主，以彈性元件的形變指示壓力，但這種結(jié)構(gòu)尺寸大、質(zhì)量重，不能提供電學(xué)輸出。隨著半導(dǎo)體技術(shù)的發(fā)展，半導(dǎo)體壓力傳感器也應(yīng)運而生。其特點是體積小、質(zhì)量輕、準(zhǔn)確度高、溫度特性好。特別是隨著MEMS技術(shù)的發(fā)展，半導(dǎo)體傳感器向著微型化發(fā)展，而且其功耗小、可靠性高。
