What are the common measuring ranges of pressure gauges?
Common is mainly from 0~60Mpa, mainly divided into four measuring range: 0.04~0.6Mpa, 0.1~6Mpa, 1~25Mpa,, 1~60Mpa, in which 1~25Mpa is relatively small, and the other two measuring ranges are more common
0.25mp, 0.6mp, 1.0mp, 1.6mp, 2.0MP, 2.5MP and so on. In order to ensure that the elastic element can work reliably in the safety range of the elastic deformation, the pressure gauge range is selected not only according to the measured pressure, but also should consider the measured pressure change rate, the range need to leave enough room for. When measuring the steady pressure, the maximum working pressure shall not exceed 2/3 of the measuring range; the pulsating pressure shall be measured; the maximum working pressure shall not exceed 1/2 of the measuring range; when measuring the high pressure, the maximum working pressure shall not exceed the 3/5 of the measuring range. In order to ensure the accuracy of measurement, the minimum operating pressure should not be less than 1/3 of the measuring range. According to this principle, according to the measured maximum pressure to calculate a value, from the pressure gauge product catalog select a little larger than the measurement range.The pressure gauge is divided into vacuum meter, pressure vacuum meter, micro pressure meter, low pressure meter, middle pressure meter and high voltage meter according to its measuring range. Used to measure the atmospheric pressure is less than the pressure value of the vacuum gauge; pressure vacuum gauge used to measure the atmospheric pressure is larger than the pressure value; micro pressure gauge for measuring the pressure value is less than 60000 Pa; low voltage meter for measuring 0~6MPa value of pressure; pressure meter for measuring 10~60MPa value of pressure; pressure gauge for measuring the pressure value of more than 100MPa.
