Troubleshooting and performance analysis of digital pressure gauge?

1、 Precautions for site use

1. The field service conditions of digital pressure gauge shall meet the requirements of technical parameters of this instrument. The instrument range shall be selected correctly. The measured pressure shall not exceed the upper and lower limits of the instrument, and sufficient overpressure safety margin shall be reserved.

2. The measured medium temperature of the digital pressure gauge shall not exceed the working temperature range of the instrument, and the sealing and vibration resistance of the instrument shall be ensured when it is used in corrosive and vibration places.

3. The digital pressure gauge is a vertical downward direct installation type, which can be directly installed on the pressure interface of the measured pipeline. During installation, avoid the formation of "closed pressure" between the instrument connecting thread and the valve in front of the gauge (observe the indicated value and pay attention to the pressure response time). If this pressure is formed, it should be eliminated in time, otherwise the measuring element will be damaged and the medium will leak.

2、 Operating instructions

The sensor and display processing part of the digital pressure gauge adopts an integrated design structure, which is easy to use. The digital pressure gauge and the tested mechanism are directly connected by threads, and there is no requirement on the placement angle of the digital pressure gauge. Before using the measurement, the approximate pressure range of the measured target should be estimated to avoid mechanical damage to the sensor due to excessive pressure exceeding the measurement range. The pressure response time of the digital pressure gauge is 2S.

3、 Troubleshooting

Digital pressure gauge belongs to mechanical and electrical products. During transportation and use, due to environmental interference and improper human operation, the instrument may not work and display normally. For simple faults, users can eliminate them by themselves. Other faults need to be returned to the manufacturer for repair. The following list shows the troubleshooting methods.

Troubleshooting of digital pressure gauge

1. There is no font on the screen. Replace the battery

2. When the pressure increases, the font does not change. Take out the battery, wait for 30 seconds, and then reinstall it

3. The font is damaged by non digital LCD, which shall be returned to the factory for repair.

4. The value is obviously inaccurate and the sensor is damaged. It should be returned to the factory for repair.

5. The accuracy is changed and returned to the factory for re calibration

Performance analysis of intelligent digital pressure gauge!

1. Economic benefit analysis

After long-term operation, the intelligent digital pressure gauge shows that the fault rate is low, the maintenance cost is low, and the operation cost is reduced. The maintenance workload is very small, mainly for regular inspection and verification. Even if there is a problem, it can be easily found through manual operation to reduce unnecessary waste discharge. The price of intelligent digital pressure gauge is higher than that of ordinary pressure gauge. Although the cost is increased, its service life and accuracy grade are much higher than that of traditional pressure gauge.

2. Analysis of progressiveness of Technology

The intelligent digital pressure gauge has few movable parts, small maintenance workload, high accuracy and reliable operation. It is convenient to set, correct and debug through manual operation, with strong operability and compatibility, convenient debugging, multi parameter measurement and wide measurement range.

3. Precautions:

The intelligent digital pressure gauge must be consistent with the on-site installation position during indoor calibration, otherwise, it will cause large zero error.

4. Concluding remarks

The long-term use of customers shows that the intelligent digital pressure gauge has a wide range of applications in industry, petrochemical industry and other fields, and is also the inevitable trend of field instrument development in the future. It is of great significance to reduce costs and improve economic benefits.
