压力表的允许误差计算公式！

通常可以通过以下公式计算：允许误差 = ±（测量上限 - 测量下限）× 精度等级%  。

比如：一个测量范围是 0 - 10MPa，精度等级为 1.6 的压力表，其允许误差就是 ±（10 - 0）× 1.6% = ± 0.16MPa  。

要注意，精度等级是压力表的一个重要参数，常见的精度等级有 1.6、2.5 等。

通过这个公式，我们就能清楚地知道某个压力表的允许误差范围。

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.
