- Q: Precision pressure gauge manufacturers can achieve precision 0.05 pressure gauges?
- The accuracy of the digital table is followed by 2.5, 1.6, 0.5, 0.4, 0.2, 0.1, 0.05
- Q: What does the pressure gauge 1% mean?
- 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.
- Q: Where is the pressure gauge checked?
- Verification mechanism of pressure gaugeGenerally determined by the use of the pressure gauge1, the use of the production site, the use of units (with certification personnel) self certification2, as a standard table, the pressure gauge by the city / Province Department of measurement and verification (Technical Supervision Bureau) certification3. Used for safety, trade, quality and environment inspection by relevant department.
- Q: What is the maximum working pressure 6Mpa? How much do you want to fit the pressure gauge?
- Selection of measuring range1, when the pressure is stable, the upper limit of measurement range is 1/3 2/3,2 measuring the fluctuating pressure, the upper limit of the measurement range of 1/3~1/23 measuring high and medium pressure (greater than 4MPa) shall not exceed 1/2 of the upper limit of instrument measurement range
- Q: When the pressure vessel is in hydraulic test, is the pressure gauge container good or the following?
- The answer is: absolutely different!!Because all media have density p, and the pressure vessel exists in the upper and lower positions, there is a height difference h between the upper and lower positions, and G=p*g*h is obtained according to the density formulaTherefore, the two readings indicate that the values are inconsistent, but the pressure is greater and the height difference is small. This part of the pressure value can be neglected.
- Q: What's the meaning of diaphragm pressure gauge YTP-100?
- Refers to the dial diameter of 100
- Q: Why is the stop valve in front of the pressure gauge?
- Use the corresponding work pressure gate valve or ball valve
- Q: What is the coefficient of error for the 2.5 grade pressure meter?
- Table 2.5% of the range is an inaccurate thermometer
- Q: What do you think of the pressure gauges with snow?
- There are two scale tables and multi scale forms in the air conditioning snow scale. We usually read the outer ring scale, and the other scales have the following indication, which represents the evaporation pressure of refrigerants under different refrigerants.?The outer ring (black scale) for pressure values, in the 2 circle (red scale) are a number of snow (R22, R12) corresponding to the temperature value.
- Q: Pressure gauges M20*1.5, M14*1.5 need to be equipped with DN how many valves, and pressure gauges, elbow and connector specifications, models
- Yes, DN15 is OK
