精密壓力表的原理與特點
一、精密壓力表的原理
當被測介質的壓力作用于彈性元件后，使其產生彈性變形—位移，經拉桿帶動傳動機構放大，由指示裝置指示被測壓力。
二、精密壓力表的特點
精密壓力表是用于工業檢測壓力的高精度壓力表，它的主要特點表現為：
1.精密壓力表結構簡單，便于攜帶。
2.精密壓力表內部采用了獨特的工藝技術，不受環境的溫濕度影響，即使是連續工作也不影響其精度，精度等級為0.25% 和0.4%。
3.精密壓力表的量程范圍寬泛。
4.精密壓力表的標度線下設置有鏡面環（A型B型），用戶不僅可以直接從表盤里讀取數值，而且該數值更加清晰精確。
5.精密壓力表可以測量無腐蝕性、非結晶、非凝固介質的壓力。
