| Smart pressure transmitter is a precision, intelligent pressure parameters on-site inspection instruments, industrial process measurement and control. It has an extremely wide range of applications. It can be used to measure a variety of media in a liquid, such as gas and steam pressure,absolute pressure and differential pressure, if the temperature sensor and throttle device (orifice, etc.) mounted, it can measure fluid flow parameters, and by the pressure secondary conversion transmitter components, It can convert the measured parameter to4-20mA standard signal, while the transmitter HART protocol can also be used to transmit digital signals, in order to meet different customer needs, it can upgrade the secondary circuit board, so the transmitter with bus function, this is what we often say that the PA bus with FF bus protocol functions.Smart pressure transmitter variety is very much, It can accurately measure differential pressure from tiny to large differential pressure, and even high-pressure, level, vacuum and gravity.Smart pressure transmitter with a small size, light weight, high precision, strong communication function, and also with online display to facilitate human-machine communication. Used in the power industry, chemical industry, petrochemical industry, food industry, paper industry, iron and steel metallurgy industry automation control systems.The issue is based on smart transmitter and detailed description of the application of intelligent pressure transmitter features, design methods, manufacturing processes. For using applications features, the main transmitter introduced in different applications. In the design methods, the main discussion of the transmitter hardware configuration and software design method of simulation; In communications with HART communication, which is currently the most widely used communication protocol, this type of transmitter, can be used both4～20mA and digital communications technology, to fit the needs of different users. |
