數字壓力表的測量范圍
數字壓力表雖然具有精度高、抗沖擊、抗腐蝕、耐震動、長期穩定性好等眾多優點，但是也要用戶對其進行良好的使用，才能一直保持優越的使用性能，本篇文章就為大家介紹最重要的使用說明之一：不可超范圍測量。
數字壓力表的最佳測量范圍應保持在全量程的1/3～2/3處最好，下面小編慢慢為大家分析原因：為了保證數字壓力表可以安全可靠的工作，量程一般要大于使用最高壓力的1/3，而選用數字壓力表范圍時，按數字壓力表承壓狀況的通用性，需選全量程的1/3到2/3 ，這個范圍之內的壓力是最佳的，因為不僅測出的結果準確度高，而且也是保證數字壓力表使用壽命的重要條件。如果數字壓力表的壓力超出了這個范圍，那么壓力表內部的彈性元件便會超負荷工作，長期處于變形狀態，并最終無法恢復原本性能。（拓展：壓力表的使用注意事項）
