Stainless Steel Axial Diaphragm Pressure Gauge Sanitary Axial Diaphragm Pressure Gauge

When used to measure special media such as viscous or acid and alkali, diaphragm pressure gauges, stainless steel spring tubes, stainless steel cores, stainless steel shells or bakelite shells should be used.

In order to ensure that the elastic element can work reliably within the safe range of elastic deformation, when selecting the range of the pressure gauge, it is necessary to leave enough room according to the size of the measured pressure and the speed of the pressure change. Therefore, the upper limit of the pressure gauge It should be higher than the maximum pressure possible in process production. According to the “Technical Regulations for Chemical Automatic Control Design”, when measuring stable pressure, the maximum working pressure should not exceed 2/3 of the upper limit of measurement; when measuring pulsating pressure, the maximum working pressure should not exceed 1/2 of the upper limit of measurement; When measuring high pressure, the maximum working pressure should not exceed 3/5 of the upper limit of measurement. Generally, the minimum value of the measured pressure should not be lower than 1/3 of the upper limit value of the instrument. In order to ensure the linear relationship between the output of the instrument and the input.
