What is the difference between the 0.075%FS accuracy of the pressure sensor and the 0.5 stage?
The national accuracy of the instrument is expressed in terms of relative percentage error, relative percentage error = (measured value of the measured parameter - the standard value of the side parameter) / / (upper limit of the gauge - lower limit of the gauge) *100%Foreign countries usually use full range of 100 points to express.For the 0 - 1MPa range, if all 0.5%, and when the measurement value is 1MPa, its tolerance is 1000 000Pa x 0.5% = + 5KPa; relative error is 0.5%, the tolerance is + 5KPa, they are the same, no difference.National Standards Committee has been committed to international standards, in recent years, various standards have been carried out 3 large-scale modifications, it should not be much difference. This is also the reason why some foreign countries can smoothly enter china.
The accuracy of stage 0.5 is higher than level 0.075. Level 0.5 means 0.5%.
0.075%FS, which means that the error of all points is not more than 0.075% in the whole rangeThe 0.5 stage indicates that the error of all measuring points is not more than 0.5% in the whole range.Therefore, the sensor with 0.075%FS is better than the 0.5 level sensor.
