Matters needing attention in operation of stainless steel earthquake-resistant meter

1. The application working temperature of the shock-resistant pressure gauge is -40~70℃, and the air humidity does not exceed 80%. If it deviates from the normal application ambient temperature by 20+/-5℃, the extra deviation of ambient temperature shall be recorded.

2. The shock-resistant pressure gauge must be assembled vertically, so as to maintain the same level with the measuring point. If the distance is too high, the extra deviation caused by recording in the liquid column can be ignored when accurately measuring air. When assembling, the explosion-proof mouth on the back of the watch case strap is blocked to avoid endangering the explosion-proof characteristics.

3. The detection range of normal operation of instrument panel: it shall not exceed 3/4 of the limit of accurate measurement under negative pressure and 2/3 of the limit of accurate measurement under fluctuation. Under the above two working pressure conditions, the accurate measurement of a good pressure gauge should not be less than 1/3 of the lowest value. When accurately measuring a vacuum pump, part of the vacuum is used in all applications.

4. In case of common faults such as the failure of the instrument panel needle or the loose internal structural parts, which can not operate normally, it is necessary to carry out maintenance or contact the manufacturer for maintenance.

5. Shock-resistant pressure gauges should be protected from vibration and impact to prevent damage.

6. When ordering, please indicate: instrument panel model, specification and name; Detection range of instrument panel; The accuracy level of instrument panel deviates from the outer packaging regulations and others.

What should pressure gauge pay attention to in daily work?

1. The pressure gauge must be vertical: when installing, use a 17mm wrench to tighten it, and the case should not be forcibly twisted; Collision should be avoided during transportation;

2, pressure gauge should be used in the surrounding environment temperature is-25 ~ 55℃;

3, using the working environment vibration frequency < 25HZ, amplitude is not more than 1 mm;

4. In use, because the ambient temperature is too high, the indicated value of the instrument does not return to zero or the indicated value is out of tolerance. You can cut off the sealing rubber plug at the upper part of the watch case to make the inner cavity of the instrument communicate with the atmosphere.

5. The application range of the stainless steel seismic table should be between 1/3 and 2/3 of the upper limit;

6. When measuring corrosive media, media that may crystallize and media with high viscosity, isolation devices should be added;

7, the instrument should be regularly checked (at least once every three months), such as fault should be repaired in time;

8. If the instrument fails or is damaged due to poor manufacturing quality under normal storage and use conditions within half a year from the date of delivery, the company shall be responsible for repairing or replacing it;

9. Instruments for measuring corrosive media are needed, and the requirements should be indicated when ordering.
