bellows）作為感受壓力的敏感元件的壓力計(jì)，這是一種彈性式壓力計(jì)。波紋管又稱皺紋箱，它是一種表面上有許多同心環(huán)狀波形皺紋的薄壁圓管。當(dāng)波紋管作為壓力敏感元件時，將波紋管開口的一端連接于固定的基座上，壓力由此傳至管內(nèi)。在壓力的作用下，波紋管伸長或收縮一直到壓力與彈性力平衡為止。這時管的自由端就產(chǎn)生一定位移，通過傳動放大機(jī)構(gòu)后，使指針轉(zhuǎn)動顯示讀數(shù)。波紋管自由端的位移與所測壓力成正比。波紋管可以分成單層和多層。在總厚度相同的條件下，多層波紋管的內(nèi)部應(yīng)力小，能承受更高的壓力，耐久性也有所增加。在壓力或軸向力的作用下，波紋管將伸長或縮短，由于它在軸向容易變形，所以靈敏度較高。波紋管對于低壓力（3000Pa~0.5MPa）比彈簧管和膜片靈敏，而且所能產(chǎn)生用以轉(zhuǎn)動指針或記錄筆的力也比較大。增加了彈簧后的多層波紋管的測壓范圍可以達(dá)到7MPa（可測量壓水堆核電廠二次側(cè)蒸汽的壓力）。</p><p style="text-indent:25px">考慮到不同使用地點(diǎn)的重力加速度和空氣浮力對轉(zhuǎn)換的影響，稱重傳感器的性能指標(biāo)主要有線性誤差、滯后誤差、重復(fù)性誤差、蠕變、零點(diǎn)溫度特性和靈敏度溫度特性等。在各種衡器和質(zhì)量計(jì)量系統(tǒng)中，通常用綜合誤差帶來綜合控制傳感器準(zhǔn)確度，并將綜合誤差帶與衡器誤差帶聯(lián)系起來，以便選用對應(yīng)于某一準(zhǔn)確度衡器的稱重傳感器。國際法制計(jì)量組織(OIML)規(guī)定，傳感器的誤差帶δ占衡器誤差帶Δ的70%，稱重傳感器的線性誤差、滯后誤差以及在規(guī)定溫度范圍內(nèi)由于溫度對靈敏度的影響所引起的誤差等的總和不能超過誤差帶δ。這就允許制造廠對構(gòu)成計(jì)量總誤差的各個分量進(jìn)行調(diào)整，從而獲得期望的準(zhǔn)確度。傳感器重要性不言而喻。</p><div

style="text-indent:25px">光敏電阻傳感器是通過把光強(qiáng)度的變化轉(zhuǎn)換成電信號的變化來實(shí)現(xiàn)控制的，它的基本結(jié)構(gòu)包括光源,光學(xué)通路和光電元件三部分，它首先把被測量的變化轉(zhuǎn)換成光信號的變化,然后借助光電元件進(jìn)一步將光信號轉(zhuǎn)換成電信號。由于光敏電阻傳感器是一種依靠被測物與光電元件和光源之間的關(guān)系，來達(dá)到測量目的的，因此光敏電阻傳感器的光源扮演著很重要的角色，光敏電阻傳感器的電源要是一個恒光源，電源穩(wěn)定性的設(shè)計(jì)至關(guān)重要，電源的穩(wěn)定性直接影響到測量的準(zhǔn)確性，常用光源有以下幾種：發(fā)光二極管是一種把電能轉(zhuǎn)變成光能的半導(dǎo)體器件。它具有體積小、功耗低、壽命長、響應(yīng)快、機(jī)械強(qiáng)度高等優(yōu)點(diǎn)，并能和集成電路相匹配。因此，普遍地用于計(jì)算機(jī)、儀器儀表和自動控制設(shè)備中。稱重傳感器實(shí)際上是一種將質(zhì)量信號轉(zhuǎn)變?yōu)榭蓽y量的電信號輸出的裝置。進(jìn)口熱電阻溫度變送器代理銷售</p><p
