The role of high-speed response fiber optic pressure sensor FPI-HS in laboratory water pressure monitoring

The laboratory (Laboratory/Lab) is the place where the experiment is conducted. The laboratory is the cradle of science, the base of scientific research, the source of scientific and technological development, and it plays a very important role in the development of science and technology. Laboratories can be divided into three categories according to their attribution: the first category is a laboratory that belongs to the university or is managed by the university; the second category is a national institution, and some are even international institutions; the third category is directly attributable to laboratories In the industrial enterprise sector, it provides services for the development and research of industrial technology.

Refers to the pressure of water. When a container is used to hold water, due to the gravity of the water, there is a pressure equivalent to that much weight, which acts on the wall and bottom of the container. The water contained in the container has a pressure effect on the side and bottom surfaces, and the pressure is always perpendicular to the contact surface on any surface. And when the depth is the same, the pressure is the same; the deeper the liquid, the greater the pressure. For example, a thin plastic sheet is added to one end of a glass tube with two open ends, and the open end is upward. When it is put into the water, the sheet will not fall. This is because there is the force of water to lift upwards (that is, upward pressure). Then slowly pour water into the glass tube little by little. When the water surface inside the tube is not close to the water surface outside the tube, the plastic sheet will not fall off. This proves that the water has upward pressure, giving the sheet a supporting force. Continue to add water until the water surface inside and outside the tube is equal, the downward pressure of the water column in the tube is equal to the upward pressure on the sheet outside the tube, and the plastic sheet falls due to the weight of the plastic sheet itself. At this time, the downward pressure on the bottom sheet of the tube is the weight of the water column in the tube, and the upward pressure on the tube is the weight of the water removed by the tube. The two are equal but opposite in direction, and then they cancel and become equal to zero. Falling due to gravity. If the glass tube is placed obliquely, the result is the same. That is, the pressure of the water is upward, and there is pressure on all sides.
Generally, the water pressure of tap water is about 0.7 kg, and 1 MPa is equal to 10 kg of water pressure. 1MPa=10kg/square centimeter, MPa megapascal is the new unit. According to the tap water supply specification: tap water, generally considered to be 0.1Mpa=10 meters, the nationally prescribed pipe network tip supply pressure is 0.14Mpa, more intuitively speaking, 0.1MPa is equivalent to a standard atmospheric pressure, and the pipe network tip supply pressure is 0.14 Mpa is equivalent to a height of 14 meters from the water tap to the water supply tower (pool). Therefore, the higher the home, the lower the water pressure.
1. Water pressure has nothing to do with the amount of water, only with the depth and density of the water. (The deeper the water, the greater the water pressure; the greater the density, the greater the water pressure). In real life, the water pressure in the home is also affected by the bending degree of the water pipe. The more bending times, the water pressure will be reduced. small.
2. The deeper the water, the greater the water pressure.
3. At the same depth, the pressure
monitoring system on all sides is one of the most used systems in security systems. The most suitable site monitoring system on the market is handheld Type video communication equipment, video surveillance is now the mainstream. From the earliest analog surveillance to the fiery digital surveillance in previous years and then to the now emerging network video surveillance, earth-shaking changes have taken place. As IP technology gradually unifies the world today, it is necessary for us to re-understand the history of the development of video surveillance systems. From a technical point of view, the development of video surveillance systems is divided into the first generation of analog video surveillance systems (CCTV), to the second generation of digital video surveillance systems (DVR) based on "PC+Multimedia Card", to the third generation of video surveillance based entirely on IP networks System (IPVS).
