Let's learn the knowledge of the pressure gauge

We often see in real life pressure gauge, such as gas pressure gauge, to bring the car charge pressure pump pressure gauge, boiler with the pressure gauge and bring many convenience to our life, but you know how they work? What it has structure of? Let's learn. Principle of pressure gauge, pressure gauge by sensitive element (in the table Bourdon tubes, bellows, bellows) Elastic deformation, the pressure deformation by the transformation of movement in table to Pointers, cause the hands to display the pressure. Pressure gauge structure: joint, cover ring, panel, pointer, connecting rod, the movement, pointer, pan. Pressure gauge classification: 1. According to the precision degree of ordinary pressure gauge and pressure gauge. 2. According to the measuring range: vacuum meter, micro pressure table, medium voltage table, low pressure table and high pressure table. 3. According to the display methods of points: pointer gauge and digital pressure gauge. Say so many kinds of pressure gauges, pressure gauge for you is have a further understanding and the understanding, don't understand is it doesn't matter, later will slowly introduce is how to use it in our life, how to control the size of its pressure, how to install and pay attention to in the installation place.
