What is the maximum working pressure 6Mpa? How much do you want to fit the pressure gauge?
Select 0-10MP.The pressure gauge is usually 1/3-1/2 larger than the maximum working pressure. When the pressure fluctuates greatly, 2-3 times of the rated working pressure should be chosen.The reason for this selection is that:1 keep the measurement indication clear;2. Head work in non limit state, reduce head mechanical fatigue, extend service life;3. Prevent peak work pressure damage meter.
~15mpa, according to the use of pressure 2~3 times the range, the use of reliable.
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
