There are many types of pressure transmitters, which can be divided into diffusion silicon pressure transmitters, monocrystalline silicon pressure transmitters, capacitive pressure transmitters, ceramic pressure transmitters, etc. Among them, there are more applications of diffusion silicon pressure transmitters. Diffusion silicon pressure transmitters are widely used in petroleum, chemical, steel, electric power, light industry, environmental protection and other industrial fields. The diffusion silicon pressure transmitter can realize the measurement and control of gauge, negative pressure or absolute pressure of various fluid pressures, and can be suitable for a variety of harsh and dangerous environments and corrosive media. How do we choose a diffusion silicon pressure transmitter? First of all, consider whether the application environment is indoor or outdoor The diffusion silicon pressure transmitter has certain requirements for the working temperature and working humidity of the site, and the protection level of different types of diffusion silicon pressure transmitters is different. If the humidity of the working environment exceeds 90% or there is rain splashing on site, it is necessary to choose a waterproof diffusion silicon pressure transmitter with protection class IP68. Secondly, the characteristics of the measured medium of the diffusion silicon pressure transmitter should be considered The main thing is to pay attention to the physical properties and state of the measured medium of the diffusion silicon pressure transmitter. For example, strong acid, strong alkali, viscosity, easy to solidify, crystallize and gasification and other working conditions. Because viscous and crystalline substances tend to block the impulse holes, so that the core cannot contact the medium, it is necessary to use a flat film diffusion pressure transmitter for measurement. The flat film diffusion silicon pressure transmitter can ensure that the medium is in direct contact with the diaphragm, which is mostly used in the general food and pharmaceutical industries. Then, it is necessary to consider whether the diffusion silicon pressure transmitter should be used in explosion-proof sites For example, petrochemical industry, boilers, thermal power units, mine oil tanks and other working conditions, there are certain requirements for the explosion-proof performance of diffusion silicon pressure transmitters. Diffusion silicon pressure transmitters are divided into intrinsically safe explosion-proof type and isolated explosion-proof type. When purchasing a diffusion silicon pressure transmitter, we must pay attention to the selection of explosion-proof performance.
