Stainless Steel Pressure Gauge Requires Higher
- Jul 11, 2017 -

Stainless steel pressure gauges are widely used in petroleum, chemical, chemical fiber, Stainless Steel Pressure Gauge metallurgy, power plants and other industrial sectors to resist corrosion, Stainless Steel Pressure Gauge seismic requirements of the higher process to measure the pressure of a variety of fluid media.

Installation Precautions

1. The instrument must be mounted vertically and shall be kept at the same level as the measuring point. Otherwise, the additional error caused by the liquid level difference shall be included accordingly.

2. Handling and installation should avoid collision and vibration, Stainless Steel Pressure Gauge including the environment and contact with equipment, piping and so on.

3. The instrument should be in the ambient temperature of -40 ℃ ~ +70 ℃, the relative humidity of not more than 85% of the use of the use of ambient temperature if the deviation is too large, Stainless Steel Pressure Gauge the temperature should be considered additional error.

4. The instrument shall not exceed 2/3 of the upper limit of the measurement when measuring the steady load. Stainless Steel Pressure Gauge The measured fluctuation pressure shall not exceed 1/2 of the upper limit of the measurement and the minimum pressure shall not be less than 1/3 of the upper limit of the measurement The The measured pressure should be kept at about two-thirds of the full scale of the instrument.

5. In the measurement of corrosive media, Stainless Steel Pressure Gauge the possible crystallization of the medium, the viscosity of large media and drastic fluctuations should be added to the isolation device and buffer device.

6. Instrument storage environment around the air can not contain harmful impurities can cause corrosion, and the relative humidity can not be too much air.

7. Before and after use of the instrument should be properly kept, avoid collision and strong vibration.

8. The meter should be inspected frequently (at least once every three months) and found to be faulty and promptly repaired.

9. Please specify the medium to be measured at each time you order to use the better material.

1. The choice of dial size: pressure gauge dial diameter are the following: 40mm, 50mm, 60mm, 100mm, 150mm, there is a special is 250mm, Stainless Steel Pressure Gauge please customers according to their needs to select the corresponding dial diameter.

2. The choice of pressure range: the pressure range of 0-0.1,0.16,0.25,0.4,0.6,1,1.6,2.5,4,6,10,16,25,40,60, vacuum table only a pressure range Is -0.1-0

3. The connection of the joint: the size of the joint of the pressure gauge varies according to the size of the dial, in general, the diameter of 40 is M10 * 1, the diameter of 50 and 60 is M14 * 1.5, the diameter of 100 and 150 is M20 * 1.5.

4. Material selection: pressure gauge material is divided into three, 1. General pressure gauge, iron, copper movement, copper joints. 2. Shell stainless steel pressure gauge, stainless steel shell, copper movement, Stainless Steel Pressure Gauge copper connector. 3. All stainless steel pressure gauge, Stainless Steel Pressure Gauge stainless steel shell, movement and joints.

5. Seismic options: pressure gauge according to the different seismic capacity of the general pressure gauge and seismic pressure gauge, Stainless Steel Pressure Gauge seismic pressure table table filled with damping oil (glycerol or silicone oil) and supporting buffer device.

6. Installation direction selection: pressure gauge is divided into radial installation and axial installation, radial installation refers to the dial and the ground into the vertical direction of the installation; Stainless Steel Pressure Gauge and axial installation is the dial and the ground into a horizontal state of the installation.

7 different precision level selection: Stainless Steel Pressure Gauge most of the pressure gauge accuracy level of 2.5 or 1.5, and only precision pressure gauge accuracy level of 0.4 or 0.25 level.
