style="text-indent:25px">壓力變送器的主要作用把壓力信號傳到電子設(shè)備，進而在計算機顯示壓力其原理大致是：將水壓這種壓力的力學(xué)信號轉(zhuǎn)變成電流（4-20mA）這樣的電子信號壓力和電壓或電流大小成線性關(guān)系，一般是正比關(guān)系。所以，變送器輸出的電壓或電流隨壓力增大而增大由此得出一個壓力和電壓或電流的關(guān)系式壓力變送器的被測介質(zhì)的兩種壓力通入高、低兩壓力室，低壓室壓力采用大氣壓或真空，作用在δ元（即敏感元件）的兩側(cè)隔離膜片上，通過隔離片和元件內(nèi)的填充液傳送到測量膜片兩側(cè)。內(nèi)江壓力變送器推薦</p><div

3.安裝時應(yīng)根據(jù)產(chǎn)品連接方式和螺紋類型，查對現(xiàn)場接口是否與產(chǎn)品接口一致，連接時應(yīng)慢速擰緊，不能把轉(zhuǎn)矩直接加到變送器殼體上，只能加在壓力接口的六方上。 </p> <p> 4.接供電電源時應(yīng)嚴格按照我公司接線說明進行連接。 </p> <p> 5.變送器過載壓力不可超過量程的200％。 </p> <p> 6.使用中發(fā)現(xiàn)異常，應(yīng)關(guān)掉電源，停止使用，進行檢查，或直接向我公司技術(shù)部門聯(lián)系。 </p> <p> 7.運輸、儲存時應(yīng)恢復(fù)原包裝，存放在陰涼、干燥、通風(fēng)的庫房內(nèi)。 </p> <p> 8.本產(chǎn)品包用期為12個月 </p> <span

選擇恰當(dāng)?shù)奈恢茫寒?dāng)壓力傳感器的安裝位置太靠近生產(chǎn)線的上游時，未熔融的物料可能會磨損傳感器的頂部；如果傳感器被安裝在太靠后的位置，在傳感器和螺桿行程之間可能會產(chǎn)生熔融物料的停滯區(qū)，熔料在那里有可能產(chǎn)生降解，壓力信號也可能傳遞失真；如果傳感器過于深入機筒，螺桿有可能在旋轉(zhuǎn)過程中觸碰到傳感器的頂部而造成其損壞。一般來說，傳感器可以位于濾網(wǎng)前面的機筒上、熔體泵的前后或者模具中。 </p> <p> 仔細清潔；在使用鋼絲刷或者特殊化合物對擠出機機筒進行清潔前，應(yīng)該將所有的傳感器都拆卸下來。因為這兩種清潔方式都可能會造成傳感器的震動膜受損。當(dāng)機筒被加熱時，也應(yīng)該將傳感器拆卸下來并使用不會產(chǎn)生磨損的軟布來擦拭其頂部，同時傳感器的孔洞也需要用清潔的鉆孔機和導(dǎo)套清理干凈。 </p><div

2088壓力變送器選用進口壓力芯片，敏感元件采用擴散或離子注入等工藝形成電阻并連接成惠斯通電橋，用微機械加工技術(shù)在電橋下形成壓力敏感膜片。當(dāng)壓力作用在膜片上時，電阻值發(fā)生變化并且產(chǎn)生一個與作用壓力成正比的線性化輸出信號。我們在惠斯通電橋上加上直流電源，就會產(chǎn)生一個直流電壓信號的輸出。經(jīng)過二次轉(zhuǎn)換線路，實現(xiàn)兩線制4～20mA輸出。 </p> </p> <p> <p> 功能特點 </p> <p> ◆穩(wěn)定性好，滿度、零位長期穩(wěn)定性可達0.2%FS/年。在補償溫度0～70℃范圍內(nèi)，溫度飄移低于0.2%FS，在整個允許工作溫度范圍內(nèi)低于0.5%FS。 </p> <p> ◆具有反向保護、限流保護電路，在安裝時正負極接反不會損壞變送器，異常時，變送器會自動限流在35mA以內(nèi)。 </p> <p> ◆固態(tài)結(jié)構(gòu)，無可動部件，高可靠性，使用壽命長 </p> <p> ◆從風(fēng)壓到氣、水、油、蒸汽都可以進行高精度的測量，不受被測介質(zhì)質(zhì)量大小的影響。 </p> <p> ◆安裝方便、結(jié)構(gòu)簡單、經(jīng)濟耐用。 </p> 德陽壓力變送器哪家好</p><p
