Digital display pressure gauge characteristics and precautions for use
The digital pressure gauge produced by Changzhou Liangbang Instrument 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. Is a common measuring instruments, widely used in chemical, environmental protection, medicine, school, measurement, food and other 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. During the use of digital pressure gauges, note the following: 5, 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 select different elastic component materials, otherwise it can not achieve the intended purpose.

1. The general verification period for digital pressure gauges 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 to 70% of the scale limit.
3. The precision of the digital pressure gauge for work is represented by the percentage of allowable error in the limit value of the dial scale. 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.
4. 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 installed higher or farther from the post, the diameter of the dial should increase.
6, daily emphasis on the use of maintenance, regular inspections, cleaning and use records.
The digital display pressure gauge produced by our company can work as usual in a vibrating environment for a long time, and the visual display will not cause visual errors; however, traditional electric contact pressure gauges cannot achieve this.
