How to choose stainless steel shockproof meter.
1. Selection of dial diameter.
If the equipment is large or the viewing distance is long, choose a larger dial, otherwise choose the surface of the small dial.
2. Determination of measuring range.
Pressure gauges generally use the full range of 1max 2mm 2max 3, the limit of the full range of 3max 4; for greater load impact, it is recommended to use the full range of 1max 2.
3. Determination of accuracy level.
The accuracy grade of the pressure gauge is that in the production process, the accuracy grade should be selected according to the requirements of the production process, economy and practicality, testing methods, etc., and according to the allowable error required by the small measured pressure.

4. Determination of liquid material.
When measuring non-corrosive medium, choose ordinary pressure gauge (joint and elastic element material can be made of copper); when measuring corrosive medium, choose stainless steel pressure gauge (joint and elastic element material can choose 304 or 316L); when measuring medium temperature is high, it is appropriate to choose stainless steel pressure gauge.
5. Selection of thread interface specifications.
In general, it is appropriate to choose metric (national standard) thread.
The stainless steel shockproof watch should be overhauled and maintained regularly.
1.
After using for a period of time, the internal structure of the pressure gauge will be worn to varying degrees, and the pressure gauge will produce a variety of errors and faults.
In order to ensure the accuracy of measurement, it should be replaced in time in order to ensure that the instructions are correct, safe and reliable.
2.Pressure gauges also need to be cleaned regularly.
Because the interior of the pressure gauge will also be dirty, it will increase the wear of various parts, thus affecting its normal work, and seriously will make the pressure gauge malfunctioning and scrapped.
3. Pressure gauges should be installed in the pressure testing position. According to the relevant regulations, the verification cycle is generally half a year.
4. The medium in the pressure measuring part varies greatly, it is used frequently, the accuracy is required to be high, and the safety factors are taken into account. The verification period can be determined according to the actual situation.
