Barometric pressure refers to the pressure produced by the air at a certain location on the earth. The air on the Earth’s surface is affected by gravity, which creates atmospheric pressure. The density of the air layer above the earth is not equal, since the atmospheric pressure is generated by the gravity of the air, the height of the air column above it is very small, and the density is also very small, so the higher the distance from the ground, the lower the atmospheric pressure, and the greater the density of the air near the ground. Under normal conditions, for every 12 meters below 2 km, the atmospheric pressure drops by 1 mm Hg. Atmospheric pressure can be measured with an atmospheric pressure sensor or an atmospheric pressure transmitter. We will be able to convert the weight of the atmosphere into a telecommunication signal output for us to view the data called an atmospheric pressure transmitter. The barometric pressure transmitter consists of a measuring cell and a microprocessor, the function of the measuring cell is to make the measured pressure act on a certain area and convert it into displacement or strain, which is then converted by the displacement-sensitive element or strain gauge into an electrical signal that has a certain relationship with the pressure. Nowadays, the atmospheric environment is receiving more and more attention. The atmospheric pressure transmitter is an important instrument for atmospheric environment monitoring. The atmospheric pressure transmitter converts the weight of the atmosphere into an electrical signal for output, providing users with accurate scientific data. Barometric pressure transmitters are widely used: First, the atmospheric pressure transmitter can provide a standard reference for the laboratory. In many cases, the experimental process needs to be carried out under atmospheric pressure standards. Second, GPS positioning. The measurement of atmospheric pressure can make the positioning system more accurate. Conventional positioning can only determine the coordinates on a plane, but through atmospheric pressure, it is possible to locate the height and floor of the location. Third, the application of agricultural meteorological stations. Under high pressure conditions, dry weather often forms, and prolonged drought can easily lead to a reduction in agricultural yields. Low pressure creates rainy weather, but too much rain will cause flooding and severe losses to agriculture. Knowing the changes in atmospheric pressure in time can take measures in advance to protect crops and reduce crop damage. Fourth, differential pressure measurement in nuclear facilities. Stability and accuracy are important conditions to ensure the long-term normal operation of the sensor, once the sensor is damaged, it must be disposed of immediately, and it cannot be repaired and adjusted, because it has been contaminated by radiation. Fifth, the altitude meter. By measuring the air pressure and then converting it into altitude. The higher the altitude, the smaller the manometer reading. The atmospheric pressure transmitter has the characteristics of flexible installation, easy to use, simple and accurate effect, strong anti-interference, etc., the signal of the atmospheric pressure transmitter is isolated and amplified, and the frequency interception interference design has strong anti-interference ability. At the same time, the atmospheric pressure transmitter is designed with reverse wiring and overvoltage protection, current limiting protection and wide voltage. Good atmospheric pressure transmitter quality can provide effective guarantee for on-site use.
