1. Different working principles
First of all, understand that the official difference between a diaphragm shock-resistant pressure gauge and a diaphragm pressure gauge is that the working principles are different. The former puts the measurement medium in direct contact with the isolation diaphragm when measuring. The shock-resistant pressure gauge is highly recognized and produces The pressure is perpendicular to the diaphragm and upward, and the pressure value is read after the elastic deformation of the diaphragm; however, the diaphragm shock-resistant pressure gauge mainly measures the positive pressure or negative pressure under pressure, and the subsequent screw mechanism drives the new gear shaft Rotate to get the pressure value.
2. Different accuracy levels
Through the analysis of the wear-resistant pressure gauge manufacturer, it was found that the accuracy level of the easy-to-use earthquake-resistant pressure gauge, the diaphragm earthquake-resistant pressure gauge, is not as high as that of the diaphragm pressure gauge. Different accuracy levels also make their measurement ranges different, relatively Generally speaking, the pressure range measured by diaphragm pressure gauges is relatively wide, but this is not the case for all pressure gauges of different series.
3. Different elastic components
After disassembling the two shock-resistant pressure gauges, the editor found that the elastic accessory of the diaphragm pressure gauge is a spring tube, and the diaphragm in it plays an isolation role. The elastic element of the diaphragm type shock-resistant pressure gauge is a corrugated diaphragm. From its working principle, it can be seen that the measured pressure is in direct contact with the diaphragm. Therefore, the diaphragm is its core working mechanism. Only when the diaphragm is normal can the pressure value be indicated normally.
However, there is no obvious difference between the above two types of wear-resistant pressure gauges. They must ensure that the ambient temperature is appropriate during later installation, and the normal use range of the instrument must be observed and must not be used beyond the limit. During the later use of the shock-resistant pressure gauge, if the pointer becomes loose, normal maintenance must be carried out, otherwise the fault will expand and affect the working accuracy of the wear-resistant pressure gauge.
