Pressure gauge (English name: pressure gauge) refers to the elastic element for sensing element, and instructed above ambient pressure measurement instrumentation, application is extremely widespread pressure table manufacturers, which include virtually all the industrial processes and scientific fields. In the field of heat pipe, oil and gas transmission, water supply systems, vehicle maintenance factory stores everywhere. Especially in the industrial process control and measurement process technology, due to mechanical pressure gauge flexible sensing element with high mechanical strength and the production of convenience features such as pressure table wholesale, making mechanical gauges are more widely used. In order to ensure reliable operation elastic element within the elastic deformation of the safe range, the choice of the gauge the amount of pressure gauges (Fig. 3) process must be based on the size of the measured pressure and the pressure differential gauge the speed of change, leaving enough room, therefore, the upper limit of the gauge pressure should be higher than the maximum possible value of the production process. According to "Chemical automation design technical requirements", import pressure table when measuring steady pressure, maximum working pressure should not exceed the upper limit of the measuring 2/3; fluctuating pressure measurements, the maximum working pressure should not exceed the upper limit of the measurement 1/2; When measuring high voltage, maximum working pressure should not exceed the upper limit of the measuring 3/5. Minimum generally measured pressure should not be less than 1/3 of the instrument to measure value. Thus ensuring a linear relationship between the output and the input volume meter between the amount calculated in accordance with the instrument on the maximum and minimum values ??of the measured parameters, after the limit, this value can not be directly used as the measuring range of the instrument. When we limit the choice of the instrument scale, should be selected in the standard series of national regulations. China's gauges measuring range Standard series:. -0.1-0.06,0.15; 0-1,1.6,2.5,4,6,10X10 "MPa (.
