儀表的測量系統(tǒng)由接頭、彈簧和傳動機構組成。通過指針指示儀表讀數(shù)。 </p> <p> YN系列耐震壓力表具有良好的抗振性能，特別適用于有機械振動和介質脈動的工作環(huán)境。耐震壓力表可測量無危險、無結晶體、不凝固以及對銅合金不起腐蝕作用的液體、氣體、蒸汽等介質的壓力。 </p> <p> <br /> </p><p> 電容式壓力傳感器 </p> <p> 它一般采用圓形金屬薄膜或鍍金屬薄膜作為電容器的一個電極，當薄膜感受壓力而變形時，薄膜與固定電極之間形成的電容量發(fā)生變化，通過測量電路即可輸出與電壓成一定關系的電信號。電容式壓力傳感器屬于極距變化型電容式傳感器，可分為單電容式壓力傳感器和差動電容式壓力傳感器。 </p> <p> <p> 應變式壓力傳感器 </p> <p> 應變式壓力傳感器是壓力傳感器中應用比較多的一種傳感器，它一般用于測量較大的壓力，廣泛應用于測量管道內部壓力、內燃機燃氣的壓力、壓差和噴射壓力、發(fā)動機和導彈試驗中的脈動壓力，以及各種領域中的流體壓力等。 </p> </p> <br /><div style="width:100%;text-align: center;"><img style="max-width: 640px;

在工業(yè)過程控制與技術測量過程中，由于機械式壓力表的彈性敏感元件具有很高的機械強度以及生產(chǎn)方便等特性，使得機械式壓力表得到越來越***的應用。 </p> <p> 機械壓力表中的彈性敏感元件隨著壓力的變化而產(chǎn)生彈性變形。機械壓力表采用彈簧管（波登管），膜片，膜盒及波紋管等敏感元件并按此分類。所測量的壓力一般視為相對壓力。一般相對點選為大氣壓力。彈性元件在介質壓力作用下產(chǎn)生的彈性變形，通過壓力表的齒輪傳動機構放大，壓力表就會顯示出相對于大氣壓的相對值(或高或低)。四川壓力儀表銷售</p><p
