Pressure gauge product consumer guide
1.Pressure gauge is a kind of pressure gauge with elastic element as sensing element, which can measure and indicate environmental pressure on the instrument. In the heat pipe network, oil and gas transmission, water and gas supply systems, vehicle repair and maintenance shop and other fields can be seen everywhere. Especially in the process of industrial control and technical measurement, the mechanical pressure gauge has been applied more and more widely because of its high mechanical strength and convenient production.
2. To judge the quality of pressure gauge, first of all, check whether the product has a measuring instrument manufacturing license mark (CMC) , secondly, check whether the copper parts which affect the connection part are thin or not, and a corresponding license number is needed on the instrument, and Factory Name and unique number, if necessary, can entrust the relevant departments to test, to see whether the safety standards, there are no jerry-building and endanger the use of safety issues.
3. The accuracy of pressure gauge mainly depends on the accuracy grade on the instrument surface. Users in the selection requirements on the surface to see the degree of accuracy. The range of the pressure gauge is 3/4 of the full range, if more than a certain range of pressure gauge to choose a larger range. For the environment with large vibration impression, it is necessary to select the shock-proof pressure gauge to ensure the life of the instrument. In the use of oil-free environment, the use of oil-free pressure gauge to ensure safety.
4. The safety protection part of the pressure instrument belongs to the compulsory verification. If it has an effect on the safety, it should be inspected regularly by the inspection department.
