There are many kinds of pressure gauges, of which ordinary pressure gauges, special pressure gauges, electrical contact pressure gauges, etc. are just one of the categories, and its application is also common to machines, almost all industrial processes and scientific research fields. Someone may ask, is not all pressure gauges can be applied to any medium? The answer is obviously not! Although there are many kinds of pressure gauges, their structures and principles are basically the same, but the difference lies in their manufacturing materials and their specific additional structures. Therefore, when measuring different media and using different environments, different types of pressure gauges need to be selected as follows: First, the pressure measurement for pulsed media and mechanical vibration applications. Select shock pressure gauges. Second, the general medium, such as air, water, steam, oil, etc., can be used ordinary pressure gauges. Third, for measuring the viscosity of large, easy to crystallize, corrosive, high temperature liquid, gas or medium pressure measurement with solid floats, use diaphragm pressure gauge. Fourth, explosion-proof requirements must be selected explosion-proof type, such as explosion-proof electrical contact pressure gauge. V. Remote transmission pressure gauges can be used when remote transmission is required. Remote transmission signals include current type, resistance type, and voltage type. Sixth, special pressure gauges are required for special mediums, such as pressure gauges for ammonia and ammonia, oxygen pressure gauges for oxygen, pressure gauges for hydrogen, and acetylene pressure gauges for acetylene. For these media, we use specific pressure gauges to make the measured data more accurate and more conducive to our work, because if the pressure gauge is inaccurate, even if it is only halfway, it may cause serious problems. The consequences, so we must be careful to choose Oh!
