Pressure gauge selection precautions A pressure gauge dial diameter: can be defaulted to the pressure gauge shell diameter, generally more commonly used 40MM, 50MM, 63MM, 75MM, 100MM, 150MM, 200MM.

Pressure gauge selection precautions Second pressure gauge shell material: general pressure gauge shell material will have ABS plastic shell pressure gauge, copper shell pressure gauge, polypropylene shell pressure gauge, carbon steel shell pressure gauge (iron shell pressure gauge), 304 stainless steel Pressure gauge, the specific pressure gauge material can be selected according to the actual use environment to select the pressure gauge shell material.
Pressure gauge selection precautions Three pressure gauge connection method: pressure gauge connection method is divided into axial pressure gauge (back connection pressure gauge), radial pressure gauge (bottom connection pressure gauge), etc., according to the specific situation, if it is For panel mounting, the axial flange can be selected from the front flange side or the rear belt fixing bracket, and the radial side can be selected from the front flange side or the rear fixed side.
Pressure gauge selection precautions Four pressure gauge pressure measurement medium: There are only two kinds of standard materials for pressure gauges, namely copper alloy and 316 stainless steel. If the medium you are measuring is not suitable or corroded for these two, then The pressure gauge can be used together with the chemical seal (the function of the chemical seal is to prevent the pressure measuring component from effectively contacting the measuring medium and the measuring component in the case of measuring the medium pressure gauge, thereby protecting the measuring component and prolonging the measurement. The life of the component).
Pressure gauge selection precautions Five pressure gauge liquid filling: In some environments where mechanical vibration is relatively large, the dials of the multi-pressure gauges generally used are filled with liquid. In fact, the main function of these fluids is to increase the resistance and effectively prevent the pressure. The watch pointer keeps vibrating, so that the pressure value can be read very accurately, and it is generally used in the vicinity of the pump or in a vibrating environment. Pressure gauge selection precautions Six pressure gauge medium temperature: The measurement medium temperature of the general copper alloy measuring component is +80 degrees, and the stainless steel pressure gauge is +200 degrees. However, if the pressure gauge you choose is a liquid-filled and shock-resistant pressure gauge, the medium temperature can only reach +100 degrees. If the temperature is too high, but it is also resistant to earthquakes, the method we use is to condense the bend.
Pressure gauge selection precautions Seven pressure gauge range: Since the pressure gauge is used to measure the deformation of the component, the amplifying mechanism is used to drive the rotation of the pointer to display the pressure value. We should also pay attention to the measurement range when selecting the measurement range. The maximum pressure is 3/4 or 2/3 of the range of the pressure gauge. If the selection is large, the change of the pointer is small, and the pressure value read is not accurate. If it is small, the pressure gauge will be overloaded. And damaged.
