Precautions when using stainless steel pressure gauges
Stainless steel pressure gauge indirect measurement structure, suitable for high viscosity, easy crystallization, strong corrosion, high temperature liquid, gas or particle flow solid pressure measurement. Diaphragms are available in a variety of materials to adapt to different corrosive media.
1. The stainless steel pressure gauge should be installed correctly
1. The instrument should be installed perpendicular to the horizontal plane;
2. The pressure instrument at the measuring point is installed in the same horizontal position as the instrument, and the additional height error is corrected;
3. The distance between the instrument installation and the measurement point should be as short as possible to avoid slowness;
4. Ensure tightness and no leakage, especially flammable and explosive gas media and toxic and harmful media.
II. Stainless steel pressure gauges should be equipped with additional devices when used under the following conditions
1. In order to ensure that the stainless steel pressure gauge is not corroded by the measured medium, or affected by the viscosity and crystallization of the measured medium, an isolation device should be installed.
2. In order to ensure that the stainless steel pressure gauge is not affected by the rapid change or fluctuation of the pressure of the measured medium, a buffer is installed. Especially when the pressure increases and decreases sharply, the stainless steel pressure gauge is most likely to be damaged and scrapped, and even the spring tube may crack and leak.
3. In order to ensure that the instrument is not affected by vibration, the stainless steel pressure gauge should be equipped with damping devices and fixing devices.
4. In order to ensure that the stainless steel pressure gauge is not affected by the high temperature of the measured medium, a liquid-filled elbow device should be installed.
5. It is strictly forbidden to use special instruments in other places. It is also strictly forbidden to measure on reliable devices, and it is strictly forbidden to use general pressure gauges to measure the pressure of special media.
