壓力表的日常維護
壓力表經過長時間的使用后，其內部的機芯會逐漸出現一些變形和磨損，進而導致壓力表出現各種誤差和故障，所以壓力表在長時間使用后，需要用戶用心去維護，具體的維護方法下面由小編為大家介紹。
1.要定期對壓力表進行清洗。由于壓力表的測量介質較為廣泛，所以會經常測量不同性質的介質，這些都會造成壓力表內部不清潔，增加了儀表機件的磨損程度，從而影響了正常工作。因此，在使用了一段時間的壓力表后，要仔細清潔壓力表的內部機芯。
2.每隔半年對壓力表進行檢定。檢定項目包括檢查壓力表的外觀、（點擊：如何檢查壓力表的外觀）壓力表能否回零，壓力表的校驗，壓力表的密封性能測試等內容。如果被測介質波動大，另外壓力表的使用頻率也較高，用戶可以根據實際情況縮短檢定周期。
