</p> <p> 稱重傳感器常用材料： </p> <p> 稱重傳感器性能的好壞很大程度上取決于制造材料的選擇。稱重傳感器材料包括以下幾個(gè)部分：應(yīng)變片材料、彈性體材料、貼片黏合劑材料、密封膠材料、引線密封材料和引線材料。 </p> <p> 電阻元件材料 </p> <p> 應(yīng)變片是稱重傳感器的感應(yīng)部分，它將外力的大小轉(zhuǎn)化為電學(xué)量輸出，是傳感器較重要的組成部分，山東飛管PKE傳感器供應(yīng)商，常用的應(yīng)變片基材采用高分子薄膜材料，應(yīng)變材質(zhì)通常為高純度康銅。應(yīng)變片的性能不**與基材和康銅純度有關(guān)，還與制造工藝有關(guān)。提高工藝技術(shù)水平也是改善傳感器性能一個(gè)很重要的方面。 </p> <p> 彈性體材料 </p> <p> 稱重傳感器彈性體的作用是傳遞外力，它必須具有在受到相同力大小的時(shí)候，產(chǎn)生形變一樣，因?yàn)閼?yīng)變片就粘貼在彈性體上面，彈性體的形變就是應(yīng)變片的形變；同時(shí)它還須具有復(fù)位性，在外力消失的時(shí)候，可以自動(dòng)復(fù)位。彈性體材料 [5] 通常選擇各樣金屬，主要有鋁合金、不銹鋼和合金鋼等等。 </p> <p> 密封膠材料 </p> <p> 早期的稱重傳感器密封都采用密封膠，后來(lái)由于制造技術(shù)的發(fā)展，山東飛管PKE傳感器供應(yīng)商，用焊接技術(shù)可以提高極大傳感器的穩(wěn)定性和使用壽命，山東飛管PKE傳感器供應(yīng)商。雖然21世紀(jì)初很多采用了焊接技術(shù)，但是某些重要部位還需涂抹一些密封膠。密封膠一般都采用硅膠，硅膠具有穩(wěn)定性好的優(yōu)點(diǎn)，可以防潮、防腐蝕，絕緣性能也非常好。

</p> <p> 為了防止電渦流產(chǎn)生的磁場(chǎng)影響儀器的正常輸出安裝時(shí)傳感器頭部四周必須留有一定范圍的非導(dǎo)電介質(zhì)空間，如果在某一部位要同時(shí)安裝兩個(gè)以上的傳感器，就必須考慮是否會(huì)產(chǎn)生交叉干擾，兩個(gè)探頭之間一定要保持規(guī)定的距離，被測(cè)體表面積應(yīng)為探頭直徑3倍以上，當(dāng)無(wú)法滿足3倍的要求時(shí)，可以適當(dāng)減小，但這是以降低靈敏度為代價(jià)的，一般是探頭直徑等于被測(cè)體表面積時(shí)，靈敏度降低至70%，所以當(dāng)靈敏度要求不高時(shí)可適當(dāng)縮小測(cè)量表面積。 </p> <p> 對(duì)工作的溫度的要求 </p> <p> 一般進(jìn)口渦流傳感器最高溫度不大于180℃，而國(guó)產(chǎn)的只能達(dá)到120℃，并且這些數(shù)據(jù)來(lái)源于生產(chǎn)廠家，據(jù)相關(guān)的各種資料分析，實(shí)際上，工作溫度超過(guò)70℃時(shí)，電渦流傳感器的靈敏度會(huì)明顯降低，甚至?xí)斐蓚鞲衅鞯膿p壞，在核電站工業(yè)、渦輪發(fā)動(dòng)機(jī)制造、火箭發(fā)射、汽車發(fā)動(dòng)機(jī)檢驗(yàn)、冶金鋼鐵熔爐等領(lǐng)域必要耐高溫的電渦流傳感器耐受性必須很高，據(jù)悉英國(guó)真尚有集團(tuán)電渦流傳感器設(shè)計(jì)工程師成功研發(fā)出了能夠耐受上千攝氏度的此類傳感器。電渦流傳感器的靈敏度受溫度的影響，在軸振測(cè)量中安裝使用電渦流傳感器應(yīng)盡量遠(yuǎn)離汽封，只有特制的耐高溫傳感器如高低溫電渦流傳感器才能用于安裝汽封附近。

320px;" alt="山東飛管PKE傳感器供應(yīng)商,傳感器" src="https://tyunfile.71360.com/WaterMark/UploadFile/shchicheng/637439888163974378/9801164.jpg"></div><p> 壓力傳感器常見(jiàn)故障： </p> <p> 第一種是壓力上去，變送器輸也上不去。此種情況，先應(yīng)檢查壓力接口是否漏氣或者被堵住，如果確認(rèn)不是，檢查接線方式和檢查電源，如電源正常則進(jìn)行簡(jiǎn)單加壓看輸出是否變化。 </p> <p> 第二種是加壓變送器輸出不變化，再加壓變送器輸出突然變化，泄壓變送器零位回不去，很有可能是壓力傳感器密封圈的問(wèn)題。常見(jiàn)的是由于密封圈規(guī)格原因，傳感器擰緊之后密封圈被壓縮到傳感器引壓口里面堵塞傳感器，加壓時(shí)壓力介質(zhì)進(jìn)不去，但在壓力大時(shí)突然沖開(kāi)密封圈，壓力傳感器受到壓力而變化。排除這種故障的較佳方法是將傳感器卸下，直接察看零位是否正常，若零位正常可更換密封圈再試； </p> <p> 第三種是變送器輸出信號(hào)不穩(wěn)。這種故障有可能是壓力源的問(wèn)題。壓力源本身是一個(gè)不穩(wěn)定的壓力，很有可能是儀表或壓力傳感器抗干擾能力不強(qiáng)、傳感器本身振動(dòng)很厲害和傳感器故障；第四種是變送器與指針式壓力表對(duì)照偏差大。 </p> <p> 然后一種易出現(xiàn)的故障是微差壓變送器安裝位置對(duì)零位輸出的影響。微差壓變送器由于其測(cè)量范圍很小，變送器中傳感元件會(huì)影響到微差壓變送器的輸出。安裝時(shí)應(yīng)使變送器的壓力敏感件軸向垂直于重力方向，安裝固定后調(diào)整變送器零位到標(biāo)準(zhǔn)值。 </p> <p> <br /> </p><p> 超聲波檢測(cè)方式: </p> <p> 根據(jù)被檢測(cè)對(duì)象的體積、材質(zhì)、以及是否可移動(dòng)等特征，超聲波傳感器采用的檢測(cè)方式有所不同，常見(jiàn)的檢測(cè)方式有如下四種： </p> <p> 穿透式：發(fā)送器和接受端分別位于兩側(cè)，當(dāng)被檢測(cè)對(duì)象從它們之間通過(guò)時(shí)，根據(jù)超聲波的衰減（或遮擋）情況進(jìn)行檢測(cè)。 </p> <p> 限定距離式：發(fā)送器和接受端位于同一側(cè)，當(dāng)限定距離內(nèi)有被檢測(cè)對(duì)象通過(guò)時(shí)，根據(jù)反射的超聲波進(jìn)行檢測(cè)。 </p> <p> 限定范圍式：發(fā)送器和接受端位于限定范圍的中心，反射板位于限定范圍的邊緣，并以無(wú)被檢測(cè)對(duì)象遮擋時(shí)的反射波衰減值作為基準(zhǔn)值。當(dāng)限定范圍內(nèi)有被檢測(cè)對(duì)象通過(guò)時(shí)，根據(jù)反射波的衰減情況（將衰減值與基準(zhǔn)值比較）進(jìn)行檢測(cè)。 </p> <p> 回歸反射式：發(fā)送器和接受端位于同一側(cè)，以檢測(cè)對(duì)象（平面物體）作為反射面，根據(jù)反射波的衰減情況進(jìn)行檢測(cè)。 </p> <p> <br /> 上海持承自動(dòng)化設(shè)備有限公司主營(yíng)加速度傳感器，如有需求，我們線上及時(shí)回復(fù)！</p><div style="width:100%;text-align:

什么是TEDS智能傳感器？ </p> <p> TEDS（Transducer Electronic Data Sheets）是將存儲(chǔ)器內(nèi)置于傳感器中，利用它存儲(chǔ)傳感器的信息。制造商可以將傳感器信息例如制造商的名稱、傳感器類型、型號(hào)、序列號(hào)和校準(zhǔn)數(shù)據(jù)等儲(chǔ)存到存儲(chǔ)器中。用戶也可以存儲(chǔ)自己的信息，例如定位、較新的校準(zhǔn)日期和其它傳感器獨(dú)特的屬性。 </p> <p> 傳感器是在一種混合模式下運(yùn)行（模擬或數(shù)字）。當(dāng)傳感器在數(shù)字模式下運(yùn)行時(shí)，存儲(chǔ)在TEDS存儲(chǔ)器內(nèi)的信息才會(huì)被下載，在模擬模式下，傳感器通常作為測(cè)量設(shè)備。數(shù)字通訊跟模擬測(cè)量信號(hào)用同一根電纜傳輸。一旦從傳感器上的轉(zhuǎn)移數(shù)據(jù)傳輸完成，存儲(chǔ)區(qū)電路將關(guān)閉，傳感器恢復(fù)正常的模擬模式運(yùn)行。 TEDS傳感器可以與常規(guī)的信號(hào)適調(diào)儀一起工作，但是卻無(wú)法訪問(wèn)存儲(chǔ)器，您需要使用TEDS信號(hào)適調(diào)儀或數(shù)據(jù)采集前端來(lái)訪問(wèn)傳感器的存儲(chǔ)器。傳統(tǒng)的傳感器也可以與帶TEDS功能的信號(hào)適調(diào)儀一起使用但是不具有TEDS功能。 </p> <p> 為了普遍的適用性，TEDS傳感器遵循IEEE1451.4 智能傳感器接口標(biāo)準(zhǔn)，支持任何制造商的TEDS信號(hào)適調(diào)儀。PCB®集團(tuán)的產(chǎn)品符合此標(biāo)準(zhǔn)，已經(jīng)在全球安裝了上萬(wàn)只TEDS傳感器和信號(hào)適調(diào)儀。 </p> <p> <br />

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(jìn)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(shí)，電源線（EXC-，EXC+）與反饋線（SEN-，SEN+）就分別短接了。SEN+和SEN-是補(bǔ)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(shí)際上傳感器接收到的電壓會(huì)小于供電電壓。每個(gè)稱重傳感器都有一個(gè)mV/V的特性，它輸出的mV信號(hào)與接收到的電壓密切相關(guān)，SENS+和SENS-實(shí)際上是稱重傳感器內(nèi)的一個(gè)高阻抗回路，可以將稱重模塊實(shí)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(shí)際上傳感器輸出較大信號(hào)為（）*2=19mV，而不是20mV。此時(shí)稱重傳感器內(nèi)部就會(huì)把19mV作為較大量程，前提是傳感器必須通過(guò)反饋回路把實(shí)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(chǎng)合，否則測(cè)量存在誤差。 </p> <p> <br /> 山東飛管PKE傳感器供應(yīng)商</p><p
