精密壓力表的組成結構
精密壓力表主要由測量機構、指示部分和表殼部分等三方面組成。下面小編為大家介紹精密壓力表具體的組成。
一、精密壓力表的測量機構
精密壓力表的測量機構主要由接頭、齒輪轉動機構及彈簧管等部分組成，它的主要工作原理是在被測介質的壓力作用下，彈簧管的自由端會產生相應的位移，同時導致齒輪轉動機構也產生位移，使得齒輪發生偏轉，將壓力傳給了指示部分。
二、精密壓力表的指示部分
精密壓力表的指示部分主要由表盤、表面、分度盤及指針組成，是直接顯示壓力值的部分。
三、精密壓力表的表殼部分
精密壓力表的表殼部分主要由表蓋、表玻璃和罩殼等組成。表殼處設有供調整零位裝置，為用戶保持零值和讀數的準確性提供了方便。
