What does the pressure gauge 1% mean?
Pressure gauge accuracy of 1%, that is, the standard accuracy level of 1 pressure gauges.A pressure gauge with a rating of 1, indicating that the measuring range of the pressure meter is 1% of the full range.That is, 1MPa pressure gauge, the accuracy level is 1, that is to say, this value error is + 0.01MPa.5MPa pressure gauge, accuracy class is 1, that is to say, this value error is + 0.05MPa.If the accuracy level is 1.6, the measurement error is + 1.6%.1MPa pressure gauge, the accuracy level is 1.6, the value of this error is + 0.016MPa.
Accuracy 1% means the full range of the pressure meter, the error range is 1%, plus plus or minus.For example, a 1MPa pressure gauge with a precision of 1% means that the range of this meter is plus or minus 0.01MPa.Calculation method is: range * accuracy grade
Accuracy 1% means the full scale error range of this pressure meter is + 1%.Precision pressure gauge, is expressed as a percentage of the allowable error range of the pressure gauge, generally divided into 0.5, 1, 1.5, 2, 2.5, 3, 4 and seven grades (boiler not 3 and 4), the smaller the value, the higher the accuracy. For example, the dial range 0 ~ 2.5 MPa 2.5 precision pressure gauge, it is shown the allowable error of pointer pressure between the actual pressure value and the measured value of the medium, not more than 2.5MPa * 2.5%= + 0.0625 MPa; when the pressure gauge pressure is 0.8MPa, the actual pressure between 0.7375 ~ 0.862 5MPa.Thus, the actual error of the pressure gauge not only relates to the accuracy, but also relates to the measuring range of the pressure gauge.When the measuring range is the same, the higher the accuracy (i.e. the smaller the number), the smaller the allowable error of the pressure gauge.When the accuracy is the same, the greater the measuring range, the greater the error of the pressure gauge.It is divided by the percentage of allowable error to dial scale value, and the greater the accuracy grade, the bigger the error limit of the dial scale. The greater the measuring range of the pressure gauge, the same accuracy level of the pressure gauge, the absolute value of the pressure measurement it allows, the greater the error.
