Measurement Range Pressure Gauge To Determine
- Jan 13, 2017 -

In order to ensure that the elastic element in elastic deformation of work reliably within the security, select the pressure gauge scale, must be based on the measuredpressure of the pressure variation in size and speed, leave enough room for and,therefore, pressure gauge upper limit value should be higher than the possible maximum pressure value in the process. Under the "design technique of chemical control regulations", measurement of steady pressure, maximum working pressure should not exceed the upper limit value measurement 2/3; measuring pulse pressure, maximum working pressure should not exceed the upper limit value measurement 1/2; when measuring the pressure, maximum working pressure should not exceed the upper limit value measurement 3/5. Test pressure shall not be less than theminimum values instrument measuring ceiling values of 1/3. To ensure the instrument linear relationship between output and input.

According to the maximum and minimum values of the measured parameters calculated instrument of upper and lower limits, not numerical directly after, as the measurement range of the instrument. When we choose the instrument's ruler ceilingvalue should be selected in the series of standards prescribed by the State. Chinapressure gauge measuring range standard series are: -0.1-0.06,0.15;0-1,1.6,2.5,4,6,10X10 "MPa (where n is the natural integer. for positive and negative values).
