</p> <p> 對初始間隙的要求 </p> <p> 各種型號(hào)電渦流傳感器，都在一定的間隙電壓值下，它的讀數(shù)才有較好的線性度，所以在安裝傳感器時(shí)必須調(diào)整好合適的初始間隙，對每一套產(chǎn)品都會(huì)進(jìn)行特性試驗(yàn)，繪出相應(yīng)的特性曲線，工程技術(shù)人員在使用傳感器的時(shí)候必須仔細(xì)研究配套的校驗(yàn)證書，認(rèn)真分析特性曲線，以確定傳感器是否滿足所要測量的間隙，一般傳感器直徑越大所測量間隙也越大

</p> <p> 檢測器的產(chǎn)品范圍包括用于制藥。 </p> <p> 典型的應(yīng)用包括在工廠的加工過程中對處理相應(yīng)的攪動(dòng)容器的稱量。檢測器的力學(xué)測量和伺服水壓控制系統(tǒng)被用于紙廠、鋼廠、箔生產(chǎn)廠、電纜鋪設(shè)和鋸木廠的機(jī)器中。 </p> <p> <br /> </p><p> 加速度技術(shù)指標(biāo)： </p> <p> 傳感器主要工作特性分為有效響應(yīng)與亂真響應(yīng)兩類。 </p> <p> ●有效響應(yīng) effective response </p> <p> 在傳感器靈敏軸方向上，由輸入的機(jī)械振動(dòng)或沖擊所引起的傳感器的響應(yīng)。這種響應(yīng)是正確使用傳感器進(jìn)行測量，取得可靠數(shù)據(jù)所期望的。 </p> <p> ●亂真響應(yīng) spurious response </p> <p> 在使用傳感器測量機(jī)械振動(dòng)或沖擊時(shí)，由同時(shí)存在的其他物理因素所引起的傳感器的響應(yīng)。這種響應(yīng)是干擾正確測量的，是不期望的。 </p> <p> 有效響應(yīng)主要有： </p> <p> 靈敏度；幅頻響應(yīng)和相頻響應(yīng)；非線性度。 </p> <p> 亂真響應(yīng)主要有： </p> <p> 溫度響應(yīng)；瞬變溫度靈敏度；橫向靈敏度；旋轉(zhuǎn)運(yùn)動(dòng)靈敏度；基座應(yīng)變靈敏度；磁靈敏度；安裝力矩靈敏度；對特殊環(huán)境的響應(yīng)。 </p> <p> ●靈敏度：（Sensitivity） </p> <p> 指定的輸出量與指定的輸入量之比。 </p> <p> ●參考靈敏度：（Reference Sensitivity） </p> <p> 在給定的參考頻率和參考幅值下傳感器的靈敏度值。 </p> <p> 傳感器靈敏度越高，測量系統(tǒng)的信噪比就越大，系統(tǒng)就不易受靜電干擾或電磁場的影響。對某種具體的加速度計(jì)設(shè)計(jì)型式來說，靈敏度越高，則傳感器越重，共振頻率也越低。因此選用多大靈敏度受其重量和頻率響應(yīng)的制約。 </p> <p> <br />

2.聯(lián)軸器的緊固螺栓應(yīng)擰緊，聯(lián)軸器的外面應(yīng)加防護(hù)罩，避免人身傷害。 </p> <p> 3.信號(hào)線輸出不得對地，對電源短路,輸出電流不大于10mA· 屏蔽電纜線的屏蔽層必須與 +15V電源的公共端（電源地）連接。 </p> <p> 4.日常的計(jì)量檢定校準(zhǔn)工作中，對扭矩傳感器進(jìn)行校準(zhǔn)時(shí)，通常采用扭矩標(biāo)準(zhǔn)機(jī)來進(jìn)行。由于扭矩傳感器的精度比較高，通常為 1 級及以上的扭矩傳感器，但在實(shí)際測量工作中，除了扭矩標(biāo)準(zhǔn)機(jī)自身的不確定度之外，影響扭矩傳感器測量結(jié)果的另外一個(gè)重要因素則是傳感器與扭矩標(biāo)準(zhǔn)機(jī)之間的連接質(zhì)量，特別是對高精度扭矩傳感器的校準(zhǔn)中在不考慮扭矩標(biāo)準(zhǔn)機(jī)自身的不確定度時(shí)，連接質(zhì)量的優(yōu)劣將直接影響測量結(jié)果的準(zhǔn)確度。在現(xiàn)有扭矩傳感器測量方法中，通常都是將傳感器串接入扭矩標(biāo)準(zhǔn)機(jī)中進(jìn)行校準(zhǔn)，故而在校準(zhǔn)過程中不可避免要出現(xiàn)連接質(zhì)量可靠與否的問題。在以往為了保證連接安裝的穩(wěn)定性和牢固性，通常會(huì)采用剛性連接方式來安裝，此種方式在裝卸方面為檢測人員帶來諸多不便，加上加工零部件的加工精細(xì)度和配合間隙的存在，在實(shí)際測量過程中使得測量軸系之間的同軸度發(fā)生較大的變化，將嚴(yán)重影響測量結(jié)果的準(zhǔn)確性。

2：由于超聲波傳感器以空氣作為傳輸介質(zhì)，因此局部溫度不同時(shí)，分界處的反射和折射可能會(huì)導(dǎo)致誤動(dòng)作，風(fēng)吹時(shí)檢出距離也會(huì)發(fā)生變化。因此，不應(yīng)在強(qiáng)制通風(fēng)機(jī)之類的設(shè)備旁使用傳感器。 </p> <p> 3：噴氣嘴噴出的噴氣有多種頻率，因此會(huì)影響傳感器且不應(yīng)在傳感器附近使用。 </p> <p> 4：傳感器表面的水滴縮短了檢出距離。 </p> <p> 5：細(xì)粉末和棉紗之類的材料在吸收聲音時(shí)無法被檢出（反射型傳感器）。 </p> <p> 6：不能在真空區(qū)或防爆區(qū)使用傳感器。 </p> <p> 7：請勿在有蒸汽的區(qū)域使用傳感器；此區(qū)域的大氣不均勻。將會(huì)產(chǎn)生溫度梯度，從而導(dǎo)致測量錯(cuò)誤。 </p> <p> <br /> 重慶PCB拾音器傳感器實(shí)惠到家</p><p
