Technological development pressure transmitter: pressure, differential pressure transmitter process variable transmitter is the most important class, wide range of applications, in addition to be used for pressure, differential pressure measurement, it can also used for flow, liquid Other parameters measured position, proportion and the like. A 5000t / d cement production line Rosemount transmitters, key parts of the process in the pressure transmitter must be set, as in the kiln, kiln Rosemount transmitters agents, the top and bottom of the preheater levels, each time the wind and cooler each room to monitor the process is operating normally. According to statistics, a total of dry cement production line set up pressure transmitter is about 80 units. By measuring the pressure transmitter mechanism to points, the most commonly used capacitive, inductive, the proliferation of silicon, VW and so on. In addition to accuracy for measuring underpressure DR kiln type differential pressure transmitter is 0.5%, the rest are mostly 0.25%, which is characterized by the use of 4mA ~ 20mA transmission of analog gauges, head for the local display table Analog, turndown ratio of 6: 1 or so, the stability of six months, which is the first generation of analog transmitters. The second generation of smart transmitters, so-called intelligent concept are: sensors and transmitters are driven by the microprocessor, and their communications with the ability to self diagnose. Smart pressure transmitter in addition to high accuracy (0.1% to 0.075%) than large range (up to 100: 1) and high stability (1-5 years), but it is generally with HART protocol or production company The agreement Rosemount transmitter range, the latter's products also comply with the international standard of FF fieldbus or PROFIBUS-PA protocol, it will be replaced by digital display table can also be operated manually or by a remote configuration of the control system Beijing Rosemount transmitters, be remotely set or modify the remote transmitter configuration data. MCT multi-protocol communications (basic model and intrinsically safe) Description of? You can diagnose the transmitter, online monitoring and configuration. ? A can of HART and DE device configuration, and support all common, ordinary and specific configuration instructions handheld devices. ? During configuration, the user interface provides detailed explanations and submenus, even for the novice is also very easy to use. ? When the operator using the following functions, communication with HART devices supported:> initial device configuration. > Starts. > Changing the configuration parameters. > Determine the actual status of the particular device or process parameters. > Start internal diagnostic features of the device. ? When suppliers to introduce new DD files from the original file obsolete:> download the new device description file from the HART website. > As HART website has not been updated, you can get the latest DD files from the manufacturer's Web site. ? Integration of data plausibility check. Under the given conditions, MCT communication device does not accept configuration beyond the measuring range to avoid major mistakes.
