通過(guò)適當(dāng)?shù)膬x表，在普通大氣壓和標(biāo)準(zhǔn)溫度條件下，核實(shí)壓力傳感器的頻率反應(yīng)值。 </p> <p> (2) 核實(shí)壓力傳感器的編碼與相應(yīng)的頻率反應(yīng)信號(hào)的正確性。 </p> <p> 2. 確定具體安裝位置 </p> <p> 為了確定壓力傳感器的編號(hào)和具體安裝位置，需按充氣網(wǎng)的各個(gè)充氣段來(lái)考慮。 </p> <p> (1) 壓力傳感器必須沿著線纜進(jìn)行安裝，較好安裝在線纜接頭處。 </p> <p> (2) 每條線纜裝設(shè)壓力傳感器不少于4個(gè)，靠近電話局的兩個(gè)壓力傳感器，相距不應(yīng)大干200m。 </p> <p> (3)

應(yīng)變式載荷傳感器的靈敏度是由偏轉(zhuǎn)結(jié)構(gòu)的剛度決定的，由測(cè)量量程決定其大小。當(dāng)受力產(chǎn)生彎曲或張力時(shí)，箔式應(yīng)變計(jì)會(huì)產(chǎn)生相應(yīng)的撓曲變形，其電阻也隨之變化。例如，大部分應(yīng)變式載荷傳感器在達(dá)到滿量程輸出時(shí)，應(yīng)變片至少需要0.001到0.003英寸（25.4μm-76.2μm)的偏轉(zhuǎn)變形，這相當(dāng)于100lb到10,000lb滿量程輸出時(shí)，各自只需0.03到6.7lbs/μin的剛度。 </p> <p> 石英（二氧化硅，SiO2）壓電式力傳感器的硬度比應(yīng)變式載荷傳感器高一個(gè)數(shù)量級(jí)，作用在石英晶體上的壓力使晶體產(chǎn)生電荷輸出，而箔式應(yīng)變計(jì)則產(chǎn)生相應(yīng)的偏轉(zhuǎn)（應(yīng)變），電荷輸出的單位為皮庫(kù)（pC)。用于制造各種尺寸壓/拉力傳感器的石英敏感元件的靈敏度通常為18pC/lb(4pC/N)。 </p> <p> 壓電石英力傳感器能響應(yīng)作用在其身上的壓力，產(chǎn)生微小的應(yīng)變，并產(chǎn)生電荷輸出。其剛度約為6-100lbs/μin。該壓力使晶格極化，靜止?fàn)顟B(tài)下晶格處于不對(duì)稱排列，如圖1所示，左邊的分子處于靜止?fàn)顟B(tài)，右邊的分子由于力的作用產(chǎn)生電極化。圖1所示在力的作用下，晶體產(chǎn)生了撓曲變形，但這是原子放大圖，實(shí)際的應(yīng)變約為百萬(wàn)分之一英寸（0.05μm）。

加速度傳感器是一種能夠測(cè)量加速度的傳感器。通常由質(zhì)量塊、阻尼器、彈性元件、敏感元件和適調(diào)電路等部分組成。傳感器在加速過(guò)程中，通過(guò)對(duì)質(zhì)量塊所受慣性力的測(cè)量，利用牛頓第二定律獲得加速度值。根據(jù)傳感器敏感元件的不同，常見的加速度傳感器包括電容式、電感式、應(yīng)變式、壓阻式、壓電式等。 </p> <p> 測(cè)量軸數(shù)量 </p> <p> 對(duì)于多數(shù)項(xiàng)目來(lái)說(shuō)，兩軸的加速度傳感器已經(jīng)能滿足多數(shù)應(yīng)用了。對(duì)于某些特殊的應(yīng)用，比如UAV，ROV控制，三軸的加速度傳感器可能會(huì)適合一點(diǎn)。 </p> <p> 三軸加速度傳感器可以實(shí)現(xiàn)雙軸正負(fù)90度或雙軸0-360度的傾角，通過(guò)校正后期精度要高于雙軸加速度傳感器大于測(cè)量角度為60度的情況。 </p> <p> 外部環(huán)境的影響 </p> <p> 某些測(cè)試現(xiàn)場(chǎng)的環(huán)境較為惡劣，考慮的因素較多，如防水、高溫、安裝位置、強(qiáng)磁電場(chǎng)及地回路等，均會(huì)給測(cè)量帶來(lái)極大的影響。 </p> <p> <br /> </p><p> 扭矩傳感器基本介紹： </p> <p> 扭矩測(cè)試比較成熟的檢測(cè)手段為應(yīng)變電測(cè)技術(shù)，它具有精度高、頻響快、可靠性好、壽命長(zhǎng)等優(yōu)點(diǎn)。將**的測(cè)扭應(yīng)變片用應(yīng)變膠粘貼在被測(cè)彈性軸上，并組成應(yīng)變橋，若向應(yīng)變橋提供工作電源即可測(cè)試該彈性軸受扭的電信號(hào)。這就是基本的扭矩傳感器模式。但是在旋轉(zhuǎn)動(dòng)力傳遞系統(tǒng)中，較棘手的問題是旋轉(zhuǎn)體上的應(yīng)變橋的橋壓輸入及檢測(cè)到的應(yīng)變信號(hào)輸出如何可靠地在旋轉(zhuǎn)部分與靜止部分之間傳遞，通常的做法是用導(dǎo)電滑環(huán)來(lái)完成。由于導(dǎo)電滑環(huán)屬于磨擦接觸，因此不可避免地存在著磨損并發(fā)熱，因而限制了旋轉(zhuǎn)軸的轉(zhuǎn)速及導(dǎo)電滑環(huán)的使用壽命。并且由于接觸不可靠引起信號(hào)波動(dòng)，從而造成測(cè)量誤差大甚至測(cè)量不成功。為了克服導(dǎo)電滑環(huán)的缺陷，另一個(gè)辦法就是采用無(wú)線電遙測(cè)的方法：將扭矩應(yīng)變信號(hào)在旋轉(zhuǎn)軸上放大并進(jìn)行V/F轉(zhuǎn)換成頻率信號(hào)，通過(guò)載波調(diào)制用無(wú)線電發(fā)射的方法從旋轉(zhuǎn)軸上發(fā)射至軸外，再用無(wú)線電接收的方法，就可以得到旋轉(zhuǎn)軸受扭的信號(hào)。旋轉(zhuǎn)軸上的能源供應(yīng)是固定在旋轉(zhuǎn)軸上的電池。該方法即為遙測(cè)扭矩儀。

被測(cè)體表面的鍍層對(duì)傳感器的影響相當(dāng)于改變了被測(cè)體材料，視其鍍層的材質(zhì)、厚薄，傳感器的靈敏度會(huì)略有變化。 </p> <p> 被測(cè)體表面尺寸對(duì)傳感器的影響 </p> <p> 由于探頭線圈產(chǎn)生的磁場(chǎng)范圍是一定的，而被測(cè)體表面形成的渦流場(chǎng)也是一定的。這樣就對(duì)被測(cè)體表面大小有一定要求。通常，當(dāng)被測(cè)體表面為平面時(shí)，以正對(duì)探頭中心線的點(diǎn)為中心，被測(cè)面直徑應(yīng)大于探頭頭部直徑的1.5倍以上；當(dāng)被測(cè)體為圓軸且探頭中心線與軸心線正交時(shí)，一般要求被測(cè)軸直徑為探頭頭部直徑的3倍以上，否則傳感器的靈敏度會(huì)下降，被測(cè)體表面越小，靈敏度下降越多。實(shí)驗(yàn)測(cè)試，當(dāng)被測(cè)體表面大小與探頭頭部直徑相同，其靈敏度會(huì)下降到72%左右。被測(cè)體的厚度也會(huì)影響測(cè)量結(jié)果。被測(cè)體中電渦流場(chǎng)作用的深度由頻率、材料導(dǎo)電率、導(dǎo)磁率決定。因此如果被測(cè)體太薄，將會(huì)造成電渦流作用不夠，使傳感器靈敏度下降，一般要求厚度大于0.1mm以上的鋼等導(dǎo)磁材料及厚度大于0.05mm以上的銅、鋁等弱導(dǎo)磁材料，則靈敏度不會(huì)受其厚度的影響

厚膜傳感器是利用相應(yīng)材料的漿料，涂覆在陶瓷基片上制成的，基片通常是Al2O3制成的，然后進(jìn)行熱處理，使厚膜成形。 </p> <p> 陶瓷傳感器采用標(biāo)準(zhǔn)的陶瓷工藝或其某種變種工藝（溶膠、凝膠等）生產(chǎn)。 </p> <p> 完成適當(dāng)?shù)念A(yù)備性操作之后，已成形的元件在高溫中進(jìn)行燒結(jié)。厚膜和陶瓷傳感器這二種工藝之間有許多共同特性，在某些方面，可以認(rèn)為厚膜工藝是陶瓷工藝的一種變型。 </p> <p> 每種工藝技術(shù)都有自己的優(yōu)點(diǎn)和不足。由于研究、開發(fā)和生產(chǎn)所需的資本投入較低，以及傳感器參數(shù)的高穩(wěn)定性等原因，采用陶瓷和厚膜傳感器比較合理。 </p> <p> <br /> 北京PCB沖擊力錘傳感器質(zhì)量可靠</p><p
