Talking about the normal use and precautions of digital pressure gauges

The digital pressure gauge produced by Jinhu Mingyu Automatic Control Equipment Co., Ltd. has high precision, high stability, error ≤ 1%, internal power supply, micro power consumption, stainless steel housing, strong protection, beautiful appearance and so on. It is a common measuring instrument that is widely used in various fields. It can intuitively display the pressure changes in various process steps, insight into the formation of conditions in the product or medium flow, monitor the safety movements in the production run, and pass automatic interlocking or sensing devices. Digital pressure gauges should pay attention to the following matters during use:

1, digital pressure gauge general verification period is six months. Mandatory testing is a legal measure to ensure that the technical performance of digital pressure gauges is reliable, that the value is transmitted accurately and that production safety is effectively guaranteed.

2. The pressure range of the digital pressure gauge should not exceed 60-70% of the scale limit.

3, digital pressure gauges used for measuring the medium if there is corrosion, it must be based on the specific temperature of the corrosive medium, concentration and other parameters to choose different elastic component materials, otherwise it can not achieve the desired purpose.

4. The accuracy of the digital pressure gauge for work is represented by the allowable error as a percentage of the dial scale limit value. Accuracy grades are generally marked on the dial. When selecting a digital pressure gauge, the accuracy should be determined according to the pressure level of the equipment and the actual work requirements.

5. Dial diameter In order for the operator to be able to accurately see the pressure value, the diameter of the dial of the digital pressure gauge should not be too small. If the digital pressure gauge is mounted higher or farther from the post, the diameter of the dial should increase.

6. Pay attention to the use of daily maintenance, regular inspections, cleaning and use records.

The digital display pressure gauge can work for a long time in a vibrating environment, and the visual display will not cause visual errors; however, traditional electric contact pressure gauges cannot do this.
