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(jìn)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(cè)任何與316L相兼容的介質(zhì)。下面我們還來(lái)介紹一下壓力傳感器的防腐技巧。 </p> <p> 首先，了解被測(cè)介質(zhì)是否與316L相兼容：316，317L合金在100小時(shí)5%鹽霧測(cè)試中，都沒(méi)有出現(xiàn)腐蝕。其次，在選購(gòu)傳感器產(chǎn)品時(shí)，向供應(yīng)商咨詢介質(zhì)對(duì)壓力傳感器是否有影響；通過(guò)對(duì)彈體耐腐蝕材料的選擇，以便達(dá)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(guò)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(duì)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(lái)進(jìn)行測(cè)量，壓力傳感器未來(lái)肯定會(huì)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(lái)適應(yīng)需要。

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 /> </p><p> 超聲探頭的關(guān)鍵是其塑料外套或者金屬外套中的一塊壓電晶片。構(gòu)成晶片的材料可以有許多種。晶片的大小，如直徑和厚度也各不相同，因此每個(gè)探頭的性能是不同的，我們使用前必須預(yù)先了解它的性能。超聲波傳感器的主要性能指標(biāo)包括： </p> <p> 工作頻率 </p> <p> 工作頻率就是壓電晶片的共振頻率。當(dāng)加到它兩端的交流電壓的頻率和晶片的共振頻率相等時(shí)，輸出的能量比較大，靈敏度也比較高。 </p> <p> 工作溫度 </p> <p> 由于壓電材料的居里點(diǎn)一般比較高，特別是診斷用超聲波探頭使用功率較小，所以工作溫度比較低，可以長(zhǎng)時(shí)間地工作而不失效。醫(yī)療用的超聲探頭的溫度比較高，需要單獨(dú)的制冷設(shè)備。 </p> <p> 靈敏度 </p> <p> 主要取決于制造晶片本身。機(jī)電耦合系數(shù)大，靈敏度高；反之，靈敏度低。 </p> <p> 指向性 </p> <p>

傳感器特性與被測(cè)體的電導(dǎo)率б、磁導(dǎo)率ξ有關(guān)，當(dāng)被測(cè)體為導(dǎo)磁材料（如普通鋼、結(jié)構(gòu)鋼等）時(shí)，由于渦流效應(yīng)和磁效應(yīng)同時(shí)存在，磁效應(yīng)反作用于渦流效應(yīng)，使得渦流效應(yīng)減弱，即傳感器的靈敏度降低。而當(dāng)被測(cè)體為弱導(dǎo)磁材料（如銅，鋁，合金鋼等）時(shí)，由于磁效應(yīng)弱，相對(duì)來(lái)說(shuō)渦流效應(yīng)要強(qiáng)，因此傳感器感應(yīng)靈敏度要高。 </p> <p> 被測(cè)體表面平整度對(duì)傳感器的影響 </p> <p>

</p> <p> 被測(cè)體表面磁效應(yīng)對(duì)傳感器的影響 </p> <p> 電渦流效應(yīng)主要集中在被測(cè)體表面，如果由于加工過(guò)程中形成殘磁效應(yīng)，以及淬火不均勻、硬度不均勻、金相組織不均勻、結(jié)晶結(jié)構(gòu)不均勻等都會(huì)影響傳感器特性。在進(jìn)行振動(dòng)測(cè)量時(shí)，如果被測(cè)體表面殘磁效應(yīng)過(guò)大，會(huì)出現(xiàn)測(cè)量波形發(fā)生畸變。
