Digital pressure gauges have the characteristics of high precision, high stability, error ≤ 1%, internal power supply, low power consumption, stainless steel shell, strong protection, and exquisite appearance. It can intuitively display the pressure changes in each process link, insight into the formation of conditions in the product or medium process, monitor the safety trends in the production operation process, and use automatic interlocking or sensing devices. The following precautions should be taken when using a digital pressure gauge:
1. The general calibration cycle for digital pressure gauges is six months. Mandatory calibration is a legal measure to ensure the reliable technical performance, accurate value transmission, and effective safety production of digital pressure gauges.
The pressure range of the digital pressure gauge should not exceed 60-70% of the scale limit.
If the medium used for measuring digital pressure gauges is corrosive, different elastic element materials must be selected according to the specific temperature, concentration, and other parameters of the corrosive medium, otherwise the expected purpose cannot be achieved.
The accuracy of a digital pressure gauge used for work is expressed as a percentage of the allowable error to the limit value of the dial scale. The accuracy level of a pressure gauge is generally marked on the dial. When selecting a digital pressure gauge, the accuracy should be determined based on the pressure level of the equipment and the actual working needs.
5. In order for operators to accurately see the pressure value, the diameter of the dial of a digital pressure gauge should not be too small. If the digital pressure gauge is installed higher or farther away from the post, the diameter of the dial should be increased.
6. Pay attention to daily maintenance, conduct regular inspections, cleaning, and record usage.
The digital display pressure gauge can work normally in a vibrating environment for a long time, and the display is intuitive without causing visual errors; But traditional electric contact pressure gauges cannot achieve this.
