Differential pressure transmitter in accordance with the following selection: 1, measuring range, the required accuracy and measurement capabilities; 2, in the face of environmental measuring instruments, such as the petrochemical industry environment, flammable (toxic) and explosion hazard atmosphere exist, a higher ambient temperature; 3, the measured medium physical and chemical properties and the state, such as acids, alkalis, viscosity, easy crystallization and solidification gasification conditions; changes 4, the operating conditions, such as medium temperature changes in pressure and concentration. Sometimes also take into account the parameters from the drive to reach normal production, changes in the gas phase and liquid phase concentration and density; 5, the structure of the measured object container, shape, size, equipment attachment container and various import and export feed nozzle must be considered, such as towers, solution tank, reactor, boiler drum, Storage Tank, tank; 6, other requirements intelligent pressure transmitter, such as environmental and health requirements; 7, have a unified engineering instrument selection consideration is required to minimize different specifications, reduce spare parts 3051 smart transmitters, to facilitate management; 8, the specific requirements of process licensors. 9, the actual process conditions: 1) Consider the measured object is which type equipment. As the volume of the groove, cans, small groove, the measurement range is not much larger volume digital smart transmitter, tank, measuring range may be larger; 2) Properties and cleanliness depends on the medium, the preferred routine The differential pressure transmitters and float level transmitter, but also on contact with the medium part of the material selection; 3) some suspended solids, foams and other media available single flange differential pressure transmitter. Some easy to precipitate and easy to use plug-in crystals double flange differential pressure transmitter; 4) liquid level and high-voltage equipment for high viscosity of the medium, because the equipment can not be opening, can be used to gauge radiation measurement; [4] 5) In addition to the measurement methods and technical issues, as well as instrumentation investment issues. In summary smart transmitters, the selection of the transmitter to be technically feasible and economically reasonable, to facilitate the management as SmartLine?} Member of the product family, STG700 is a highly advanced sensor technology adoption performance pressure transmitter. STG700 by the static pressure and temperature compensated pressure sensor chip combine to provide high measurement accuracy and stability under static pressure and temperature over a wide range.
