The selection of accuracy level for pressure gauges is crucial in industrial production and laboratory pressure measurement. Today, let's compare in detail the 1.6 level and 2.5 level pressure gauges to see what the differences are and in which situations we should choose which pressure gauge.
Firstly, let's understand the concept of precision level. The accuracy level of a pressure gauge is actually the percentage of the maximum allowable error of the pressure gauge to the measuring range. Simply put, the smaller the precision level value, the more accurate the measurement results of the pressure gauge.
Taking a pressure gauge with a range of 0-1MPa as an example, the maximum allowable error for a 1.6 level pressure gauge is ± 0.016MPa, while the maximum allowable error for a 2.5 level pressure gauge is ± 0.025MPa. Numerically speaking, the error range of level 1.6 is significantly smaller than that of level 2.5. This means that under the same range and size, the production process requirements for a 1.6-level pressure gauge are higher, and the materials used are also more sophisticated, so the price will be relatively higher.
So, which situations are these two types of pressure gauges suitable for?
1.6 level pressure gauge: Due to its extremely high measurement accuracy, it is very suitable for industrial production line process monitoring, laboratory precise pressure measurement, and occasions that require accurate data recording. In these situations, pressure changes at every point may have a significant impact on product quality or experimental results, so it is necessary to choose a higher precision 1.6 level pressure gauge to ensure measurement accuracy.
2.5 level pressure gauge: Compared to 1.6 level, its accuracy requirement is lower. Therefore, it is more suitable for places that do not require high accuracy, such as viewing the approximate pressure of water storage tanks and the approximate pressure display of air compressors. In these situations, we only need to know whether there is pressure or not, and whether the pressure is sufficient, without the need for overly precise measurement results.
In addition, from the design of the dial scale, the scale of the 1.6 level pressure gauge is finer, and the reading can reach smaller division values; The scale interval of the 2.5-level pressure gauge is larger, and the reading is more rough. This also indirectly reflects their differences in accuracy
