Digital pressure gauge has the characteristics of high precision, high stability, error ≤ 1%, internal power supply, micro power consumption, stainless steel shell, strong protection, beautiful and exquisite. It is a common measuring instrument, which is widely used in various fields. It can directly display the pressure changes of each process, insight into the formation of conditions in the product or medium flow, monitor the safety trend in the production and operation process, and through automatic interlock or sensor.
The following points shall be noted in the use of digital pressure gauge:
1. The general verification period of digital pressure gauge is half a year. Compulsory verification is a legal measure to ensure the reliable technical performance, accurate transmission of quantity value and effective guarantee of safety production.
2. The range of pressure used in digital pressure gauge shall not exceed 60-70% of the scale limit.
3. If the medium used for measuring by digital pressure gauge is corrosive, it is necessary to select different elastic element materials according to the specific temperature and concentration of corrosive medium, otherwise, it can not achieve the expected purpose.
4. The accuracy of the digital pressure gauge is expressed by the percentage of the allowable error in the limit value of dial scale. The accuracy level is generally marked on the dial. When selecting digital pressure gauge, the accuracy shall be determined according to the pressure level and actual work needs of the equipment.
5. in order to make the operator can see the pressure value accurately, the diameter of the dial of the digital pressure gauge should not be too small. If the digital pressure gauge is installed higher or far away from the post, the diameter of the dial shall be increased.
6. pay attention to the use and maintenance, regularly check, clean and keep the use record. The digital display pressure gauge can work normally in the vibration environment for a long time, and the visual error will not be caused by the display intuitionism; But traditional pressure gauge of electric contact can not do this.
