電阻式傳感器是利用變阻器將被測非電量轉(zhuǎn)換為電阻信號的原理制成。電阻式傳感器一般有電位器式、觸點變阻式、電阻應(yīng)變片式及壓阻式傳感器等。電阻式傳感器主要用于位移、壓力、力、應(yīng)變、力矩、氣流流速、液位和液體流量等參數(shù)的測量。 </p> <p> 電容式傳感器是利用改變電容的幾何尺寸或改變介質(zhì)的性質(zhì)和含量，從而使電容量發(fā)生變化的原理制成。主要用于壓力、位移、液位、厚度、水分含量等參數(shù)的測量。 </p> <p> 電感式傳感器是利用改變磁路幾何尺寸、磁性位置來改變電感或互感的電感量或壓磁效應(yīng)原理制成的。主要用于位移、壓力，山東尼利可NIRECO傳感器供應(yīng)商、力、振動、加速度等參數(shù)的測量，山東尼利可NIRECO傳感器供應(yīng)商。 </p> <p>

effective response </p> <p> 在傳感器靈敏軸方向上，由輸入的機械振動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械振動或沖擊時，由同時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)運動靈敏度；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設(shè)計型式來說，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 />

</p> <p> 3、桌面嵌入式安裝。 </p> <p> 4、埋墻隱蔽安裝。 </p> <p> 注意：安裝位置盡量以談話區(qū)域為中心。安裝原則：盡量靠近主要的談話區(qū)域，這樣的拾音效果更佳。 </p> <p> 二、拾音器連接電纜的選擇及布線 </p> <p> 拾音器可以使用普通4 芯電話線、5 類網(wǎng)絡(luò)雙絞線、屏蔽/非屏蔽信號電纜等。 </p> <p> 拾音器供電一般分為兩種： </p> <p> 1、單獨供電（推薦穩(wěn)壓電源。 </p> <p> 2、集中供電（在機房集中供電），用3×0.5 RVVP芯電纜，分別為電源正、音頻信號正、公共地。電磁復(fù)雜環(huán)境可以使用屏蔽電纜，其屏蔽層單端連接設(shè)備地。即拾音器（拾音器）一端的屏蔽網(wǎng)懸空，設(shè)備端的屏蔽網(wǎng)接設(shè)備地（機殼）。注意：布線時比較好單獨走線，不要同交流電等強電使用同一纜槽，同時盡量遠(yuǎn)離變壓器、燈具整流器等強電磁干擾設(shè)備。 </p> <p> 3、怎么選擇供電電源 </p> <p> 安裝時要考慮到電源效率和線損問題，盡量選用標(biāo)稱值較高的電源。這里所指的直流穩(wěn)壓電源就是常說的“線型變壓器”，一般由電源變壓器、整流二極管、濾波電容及集成穩(wěn)壓器構(gòu)成。盡量不要使用開關(guān)電源，它可能會導(dǎo)致大量的電路雜音！市面上很多開關(guān)電源品質(zhì)差，紋波系數(shù)非常大，會引起拾音器有嗡嗡聲。 </p> <p> <br

應(yīng)變式載荷傳感器的比較大優(yōu)勢在于靜態(tài)精確度，能實現(xiàn)稱重應(yīng)用，正如本文“動態(tài)響應(yīng)”中所提及到，石英力傳感器有低頻限制，所以它們不可能做到真正的DC響應(yīng)，即靜態(tài)監(jiān)測。當(dāng)用ICP®輸出型傳感器做準(zhǔn)靜態(tài)測試或者靜態(tài)校準(zhǔn)時，必須使用一個DC耦合的信號調(diào)理儀，如484系列，并需要采用一個DC耦合的數(shù)采設(shè)備。該設(shè)備允許傳感器的DC偏置電壓調(diào)零，且不會對系統(tǒng)施加任何額外的高通濾波的影響。一般情況下，根據(jù)經(jīng)驗法則，準(zhǔn)靜態(tài)測試的輸出信號丟失與離逝時間（較早個DTC的10%時間內(nèi)）成一階線性關(guān)系，如圖6a和6b所示，因此在較早個1%DTC時，只有1%的信號損失，假如一個傳感器的DTC是2000秒，那么在較早個20秒，有1%的輸出信號衰減。 </p> <p> 重點強調(diào)（敲小黑板）：整個系統(tǒng)必須是直流耦合，這就意味著傳感器需具備較長的放電時間常數(shù)，信號調(diào)理儀和數(shù)據(jù)采集儀都是直流耦合。校準(zhǔn)是直流耦合的一種常見應(yīng)用。 </p> <p> <br /> 上海持承自動化設(shè)備有限公司主營加速度傳感器，如有需求，撥打工作手機！</p><div

如果加速度計的動態(tài)質(zhì)量接近被測結(jié)構(gòu)物的動態(tài)質(zhì)量，則會使振動產(chǎn)生明顯的衰減。為此在諸如印刷電路板等又薄又輕的片狀構(gòu)件上測振時，為了得到準(zhǔn)確的數(shù)據(jù)必須采用重量輕的加速度計。如果被測物件呈現(xiàn)單自由度的響應(yīng)，則加速度計將使其共振頻率下降。 </p> <p> ●低頻響應(yīng) </p> <p> 使用壓電加速度計時，所用放大器低頻截止頻率多為2－5Hz，目的是以此來剔除許多壓電傳感器的熱釋電輸出。像隔離剪切式設(shè)計等隔離性好的設(shè)計型式可用在較低的頻率。壓阻式和變電容式加速度計則具有零頻響應(yīng)。 </p> <p> ●高頻響應(yīng) </p> <p> 加速度計的高頻響應(yīng)隨加速度計的機械性能和安裝方法而變。在安裝牢固時，大多數(shù)加速度計呈現(xiàn)無阻尼單自由度系統(tǒng)的頻響特性。以±5%為要求的話，其頻率響應(yīng)約平整到安裝共振頻率的五分之一。如果加適當(dāng)?shù)男拚驍?shù)，則可在更高的頻率上得到有用的數(shù)據(jù)。 </p> <p> ●溫度響應(yīng) </p> <p> 傳感器靈敏度隨溫度的變化，稱為傳感器的溫度響應(yīng)。用 </p> <p> 常用壓電加速度計的溫度范圍為零度以下至+177°C 或 +260°C。某些特定型號，低溫可達(dá)零度，高溫可達(dá)760°C。很多種壓電加速度計設(shè)計型式在很寬的溫度范圍內(nèi)的溫度響應(yīng)很平。壓阻式、變電容式加速度計的典型溫度范圍為－18°C～+93°C。 </p> <p> <br

阻抗的關(guān)系如何影響傳感器測試結(jié)果？ </p> <p> 在交流AC電路中，阻抗為阻礙電流通過的所有物理量。阻抗的測量在大多數(shù)電子系統(tǒng)中有重要的作用。包含ICP®信號適調(diào)儀的測量鏈也不例外。ICP®信號適調(diào)儀的輸出阻抗和顯示設(shè)備中的輸入阻抗之間的關(guān)系在測量鏈中起到關(guān)鍵作用。這些阻抗值可以影響頻率和幅值的測量結(jié)果。 </p> <p> ICP®信號適調(diào)儀有兩種不同的輸出類型： </p> <p> 1. 非緩沖的輸出：適調(diào)儀的輸出阻抗由串聯(lián)電容和分流電阻決定。這個電阻和顯示設(shè)備的輸入阻抗組成一個并聯(lián)電路。 </p> <p> 2 .緩沖輸出：信號適調(diào)儀的輸出阻抗由信號適調(diào)儀中的位于輸出電路后端的運算放大電路決定。在這個配置中，輸出電阻不決定適調(diào)儀的輸出阻抗，與顯示設(shè)備的輸入阻抗不形成并聯(lián)電路。 </p> <p> 不同的數(shù)據(jù)采集系統(tǒng)的輸入阻抗有所不同。高阻抗輸入，大于1MΩ就不需要考慮適調(diào)儀的類型，不論是緩沖型的還是非緩沖型的。低阻抗輸入，大約50Ω，就需要考慮適調(diào)儀的輸出類型和各自受到的負(fù)面影響。對于非緩沖的輸出，放電時間常數(shù)將變短，從而影響系統(tǒng)的低頻響應(yīng)。對于緩沖輸出，信號幅值將會減小。 </p> <p>
