Sisson teach you smart pressure transmitter options (1) measuring range, the required accuracy and measurement functions; (2) measuring instruments to face the environment, such as the petrochemical industry environment, flammable (toxic) and explosion hazard atmosphere exist, there are high ambient temperatures; (3) physical and chemical properties of the measured medium and the state, such as acids, alkalis, viscosity, easy crystallization and solidification gasification conditions; changes (4) operating conditions, such as medium temperature, pressure changes, concentration. Sometimes also take into account the parameters from the drive to reach normal production, gas and liquid concentration and density change; and (5) the measured object container structure, shape, dimensions, attachment device and various import and export container tube mouth must take into account, such as towers, solution tank, reactor, boiler drum, vertical tank, tank, etc; (6) The actual process cases: ① measured object is to consider which type equipment. As the volume of the groove, cans, smaller tank, measuring range is not too large, a large tank volume, the measurement range may be larger; chemical and physical properties and cleanliness ② depends on the medium, the preferred conventional differential pressure transmitter device and float level transmitter, but also on contact with the medium part of the material is selected; ③ single flange available on some suspended solids, foams and other media. Some easy to precipitate and easy to use plug-in crystals double flange; ④ high viscosity of the liquid medium level and high-voltage equipment wholesale Kunming intelligent pressure transmitter, the unit does not opening, the choice of radiation level meter to measure; ⑤ In addition to the measurement methods and technical issues, as well as instrumentation investment issues. In summary, the selection of transmitter Kunming intelligent pressure transmitter retail technically be feasible and economically reasonable, to facilitate management. Furnace pressure transmitter range should be used to note the following questions 1. The size of the boiler furnace pressure regulating or have some differences Kunming intelligent pressure transmitter principle, the smaller oven, adjust the difficulty will increase; 2. The blast furnace pressure and linked to the general use of micro-differential pressure transmitter range, such as -100 ~ + 100Pa, more negative pressure chamber, blast increases, and vice versa, of course, the size of the wind have a significant impact on the hearth; 3. now commonly used DCS, PLC system to control, because the parameters and control can be compatible with each other, good control effect; such as small boilers can be a programmable controller to complete, but to get good the effect depends on how to debug the scene, several debugging may have a satisfactory effect.
