一般情況下，生產(chǎn)廠商會(huì)標(biāo)明1次標(biāo)定的有效使用時(shí)間為1年或2年，到期需重新標(biāo)定。其它注意事項(xiàng)濕度傳感器是非密封性的，為保護(hù)測(cè)量的準(zhǔn)確度和穩(wěn)定性，應(yīng)盡量避免在酸性、堿性及含有機(jī)溶劑的氣氛中使用。也避免在粉塵較大的環(huán)境中使用。為正確反映欲測(cè)空間的濕度，還應(yīng)避免將傳感器安放在離墻壁太近或空氣不流通的死角處。如果被測(cè)的房間太大，就應(yīng)放置多個(gè)傳感器。有的濕度傳感器對(duì)供電電源要求比較高，否則將影響測(cè)量精度。或者傳感器之間相互干擾，甚至無法工作。

當(dāng)下把振打敘述描述一下，自動(dòng)時(shí)含塵氣流從箱體下頭進(jìn)入反吹式布袋除塵器容器后，容器中的大顆粒塵埃，由于空氣流假設(shè)擴(kuò)大，流速降低，很明顯可能會(huì)沿筒壁下落；粒度細(xì)、密度小的微小塵粒懸浮于流體中通過空氣流分布裝置，均勻進(jìn)入過濾室中彌散于除塵器濾袋間隙，通過除塵器濾袋的地方的慣性碰撞、篩濾等功效而沉積在除塵器濾袋的地方，凈化流體由主風(fēng)機(jī)排出。在說一下反吹式布袋除塵器的另一個(gè)常識(shí)如下，反吹式布袋除塵器阻力值的增大是于塵埃層不斷的增厚，而且塵埃不斷附著于除塵器濾袋表面的原因；當(dāng)阻力值到達(dá)一定值時(shí)，這時(shí)操作這一部分的零件，歐特爾脈沖閥就會(huì)發(fā)信號(hào)，把持歐特爾脈沖閥開啟，高壓氣包內(nèi)的壓縮空氣通；當(dāng)然了，如果沒有灰塵了或是小到一定的程序了，掃灰工作會(huì)停止工作的。
