壓力儀表的維護原則
壓力儀表的使用性能除了自身的質量問題外，還需要用戶對其進行精心的維護，以下是壓力儀表的具體維護原則。（拓展：壓力表的使用注意事項）
1.壓力儀表的工作環境和貯存環境都應該是無塵、無腐蝕的場所，如果有特定的要求，那就需要根據特定要求來執行。
2.壓力儀表的內部元件都是高精密的產品，膜片表面不可與硬物碰撞，否則很容易損壞壓力表內部。
3.如果沒有專業的檢測技能和專用的檢測設備，用戶不可以擅自打開儀表的外殼進行檢修，更不可以擅自更換內部元件，否則壓力表的可靠性就無法得到保證。
4.部分壓力表會有足夠過載能力，但切勿嚴重過載，否則會永久損傷壓力儀表，無法恢復原狀態。
5.有些壓力表是具有抗振性能的，如耐震型壓力表，雖然有抗震設計，但安裝、使用時仍應小心輕放，并格外注意不可摔跌、沖撞。
