Selection Note editor in various kinds of instruments, the application of the transmitter broadest and most universal 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. Such as pressure transmitters, in addition to the original STD720 differential pressure transmitter for measuring pressure, it can measure the level inside the device. When pressure vessel level measurement of differential pressure transmitter STD720 imports, needed a pressure change can be. When measuring the pressure vessel level, available both pressure change, that is the lower limit of a measuring differential pressure transmitter STD720, a measurement limit their output signals can be subtracted, you can measure the level, generally used 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). Since its inception, has been committed to the application of factory automation systems, and gradually developed into a professional industrial automation systems integrators, set engineering design, sets, services in one. EPC now has the ability to fully turnkey design, procurement, construction integration in terms of alcohol production and urban heating. And provide comprehensive industrial automation engineering technical consulting, system design, product support, system integration, installation, development, commissioning, training, maintenance and other comprehensive services. It has won user recognition and respect. The company will be global for the development of professional quality, integrity and pragmatic, win-win cooperation for the development of the guidance of the business philosophy, we strive to provide our users with the best products and services.
