The development of high temperature pressure sensors plays an important role in guiding the measurement and control work. Common pressure sensors measure temperatures below 200 °C, so they cannot accurately measure pressure at high temperatures. Therefore, many scholars at home and abroad are committed to the research of high temperature pressure sensors. This paper mainly

In the trade of petroleum products, the main difference between buyers and sellers lies in the quantity and quality of products. The quantity (i.e. weight) of petroleum products is an important basis for trade settlement. The three important factors that determine the weight of oil are density, temperature and volume. Density is also related to

The traditional limestone gypsum wet desulfurization process is widely used in large-scale thermal power plants. Our plant adopts “magnesium oxide” wet flue gas desulfurization device for flue gas desulfurization. The direct by-products of desulfurization reaction are magnesium sulfite in trihydrate and hexahydrate. The corrosiveness and abrasiveness of the slurry of the desulfurization system, and the
