壓力表的允許誤差計算公式!
通??梢酝ㄟ^以下公式計算:允許誤差 = ±(測量上限 - 測量下限)× 精度等級% 。
比如:一個測量范圍是 0 - 10MPa,精度等級為 1.6 的壓力表,其允許誤差就是 ±(10 - 0)× 1.6% = ± 0.16MPa 。
要注意,精度等級是壓力表的一個重要參數(shù),常見的精度等級有 1.6、2.5 等。
通過這個公式,我們就能清楚地知道某個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.
