壓力表的允許誤差計(jì)算公式！

壓力表的允許誤差計(jì)算公式！

通常可以通過(guò)以下公式計(jì)算：允許誤差 = ±（測(cè)量上限 - 測(cè)量下限）× 精度等級(jí)%  。

比如：一個(gè)測(cè)量范圍是 0 - 10MPa，精度等級(jí)為 1.6 的壓力表，其允許誤差就是 ±（10 - 0）× 1.6% = ± 0.16MPa  。

要注意，精度等級(jí)是壓力表的一個(gè)重要參數(shù)，常見(jiàn)的精度等級(jí)有 1.6、2.5 等。

通過(guò)這個(gè)公式，我們就能清楚地知道某個(gè)壓力表的允許誤差范圍。

Calculation formula for allowable error of pressure gauge!

Usually, it can be calculated by the following formula: allowable error=± (measurement upper limit - measurement lower limit) x accuracy level%.

For example, a pressure gauge with a measurement range of 0-10MPa and an accuracy level of 1.6 has an allowable error of ± (10-0) × 1.6%=± 0.16MPa.

It should be noted that accuracy level is an important parameter of pressure gauges, and common accuracy levels include 1.6, 2.5, etc.

By using this formula, we can clearly determine the allowable error range of a certain pressure gauge.
