3.安裝時應根據(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、儲存時應恢復原包裝，存放在陰涼、干燥、通風的庫房內(nèi)。 </p> <p> 8.本產(chǎn)品包用期為12個月 </p> <span style="display:none;"></span> <p> <br />

選擇恰當?shù)奈恢茫寒攭毫鞲衅鞯陌惭b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。當機筒被加熱時，也應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套清理干凈。 </p><p> <p> 工作原理 </p> <p> BY 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> </p><div style="width:100%;text-align: center;"><img

2088壓力變送器靈敏度高、精度高、抗過載能力強。采用進口傳感器制造，傳感器和放大電路高度集成；采用壓鑄合金鋁表面噴漆殼體，電路零點和增益無須調(diào)整；抗干擾能力強，耐酸堿，長期穩(wěn)定可靠。 </p> <p> 二、工作原理 </p> <p> BY 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。遂寧壓力變送器哪家好</p> <br /><p style="text-indent:25px">遂寧壓力變送器哪家好</p><p> <p> 壓力變送器的發(fā)展大體經(jīng)歷了四個階段： </p> <p> (1)早期壓力變送器采用大位移式工作原理，如**浮子式差壓計及膜盒式差壓變送器，這些變送器精度低且笨重。 </p> <p> (2)20世紀50年代有了精度稍高的力平衡式差壓變送器，但反饋力小，結(jié)構(gòu)復雜，可靠性、穩(wěn)定性和抗振性均較差。 </p> <p> (3)20世紀70年代中期，隨著新工藝、新材料、新技術(shù)的出現(xiàn)，尤其是電子技術(shù)的迅猛發(fā)展，出現(xiàn)體積小巧，結(jié)構(gòu)簡單的位移式變送器。 </p> <p> (4)20世紀90年代科學技術(shù)迅猛發(fā)展，變送器測量精度提高而且逐漸向智能化發(fā)展，數(shù)字信號傳輸更有利于數(shù)據(jù)采集，出現(xiàn)了擴散硅壓阻式變送器、電容式變送器、差動電感式變送器和陶瓷電容式變送器等不同類型。 </p> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br />
