Selection Note editor in various kinds of instruments in STD720 differential pressure transmitter, transmitter applications most extensive and widespread, the transmitter can be divided into pressure transmitter and differential pressure transmitter. Transmitters used to measure pressure, differential pressure, vacuum, liquid level, flow and density. The transmitter has two-wire and four-wire points, two-wire transmitter, especially more; there are intelligent and non-intelligent points, smart transmitters, better; pneumatic and electric points, mostly electric transmitter ; In addition, according to the application have intrinsically safe and explosion-proof to the other; the main types according to application conditions transmitter as follows: low (micro) pressure / low differential pressure transmitter; pressure / differential pressure transmitter ; a high pressure / high differential pressure transmitter; absolute pressure / vacuum / suction differential pressure transmitter; high temperature / pressure, differential pressure transmitter; corrosion / pressure, differential pressure transmitter; easy to crystallize / pressure, differential pressure transmitter. Selection of the transmitter installation conditions generally considered on aspects, environmental conditions, the instrument performance, economy and use media. Practical application into direct measurement and indirect measurement; its use has process measurement, process control and interlock devices. Common transmitter has a common pressure transmitter, differential pressure transmitters, single flange transmitter, double flange transmitter, insert flange transmitters. Pressure transmitters and differential pressure transmitter single term perspective is measured from the pressure and the pressure difference between the two, but they are indirect measurement parameters are numerous. As pressure transmitter differential pressure transmitter STD720, except for measuring pressure, it also can measure the level inside the device. When pressure vessel level measurement, required a pressure change can be. When measuring the level of the pressurized container imports STD720 differential pressure transmitter can be used both voltage variable differential pressure transmitter STD720 imports, namely a lower limit of measurement, a measurement limit their output signals can be subtracted, ie It can measure the level, generally used in differential pressure transmitter. In the container at the level and pressure values ??remain unchanged also be used to measure the density of the medium. Pressure transmitter measuring range can be very wide, from absolute zero can to 100MPa (in general).
