Online diagnostic technology in the application of electromagnetic flow meter scale

Abstract: the on-line diagnosis technology in the application of electromagnetic flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. A on-line diagnosis technology, instrument why need? In plant control system, field instruments, Sensors and actuators) One of the key factors is the guarantee of product quality. The size of the automatic control system is more and more big, the current number field instruments is increasing. 。 More flow meter manufacturers choose model price quote you are welcome to inquire, here is the online diagnosis technology in the application of electromagnetic flow meter scale article details. A on-line diagnosis technology, instrument why need? In plant control system, field instruments, Sensors and actuators) One of the key factors is the guarantee of product quality. The size of the automatic control system is more and more big, the current number field instruments is increasing. In a complex control system, the failure of any one set of instrument or signal drift, tend to cause continuous reaction in the system, to quickly locate fault instrument and to make the system recovery is very difficult. Especially when the instrument signal drift is a gradual process, the signal drift before is beyond the limit is not too noticed by the operator. And accumulated to a certain level of the signal drift once field instrument fault formed by extreme consequences is often the whole production line must be shutdown overhaul, this means that the plant production efficiency decline and rising production costs. So-called online diagnosis instrument or instrument besides itself with the measurement or control function integrated with other diagnostic function. Fault diagnosis of the instrument is not only simple, also can monitor the impact of the external conditions for instrument, which can guarantee failure instrument rapid recovery and prevent a negative impact, so do system maintenance in advance and greatly improve production efficiency. Second, online diagnosis function of the electromagnetic flowmeter for electromagnetic sewage flow meter of high precision and convenient maintenance, so is widely used in custody transfer metering and important production process control. But the installation of the electromagnetic flowmeter can significantly affect its performance, environment and working conditions such as the concentration of the measured medium and the change of the production or the internal devices can cause pollution and corrosion of the measured values of drift or reduce the accuracy of measurement, even when the flow meter installed too close to bend or other disturbance device also can produce the error output. It is for these reasons, though electromagnetic flowmeter is reliable, people still believe that there is a lot of the flow meter installed in the factory can't accurate measurement. 1. Online diagnosis of electromagnetic flowmeter development background of the German chemical measurement and adjust the technical committee for standardization organization written & other; On the diagnosis of field instruments requirements & throughout; Users guide, the guide is mainly summary in the use of instrument in the process of the specific requirements of fault diagnosis on the spot as a guide that instrument manufacturers in product development. Given in the prominent position in the family of flowmeter, electromagnetic flowmeter is independent definition 2 in part 3 of this guideline. Section 2: electromagnetic flowmeter online diagnostic requirements. 2. A kind of electromagnetic flowmeter with self-diagnosis functions is based on the concept of guideline development of a new generation of electromagnetic sewage flowmeter converter. This type of converter in comparison with conventional electromagnetic flowmeter converter contains a signal analysis, zui new means and new testing path and assessment software, to the early fault, interference and electromagnetic flowmeter installation effect test and alarm signal is given, its comprehensive diagnosis function not only detect the unreliable measure causes of problems and told the engineer. Traditional electromagnetic flowmeter diagnostic analysis is limited to the micro controller and the memory testing instrument itself. Built-in triple diagnostic function can make the field engineer timely judge the state of instrument and the quality of the measured value. This triple diagnosis give engineers a comprehensive flow meter run information: 100% sensor and converter of microprocessor, memory, software testing, test the temperature of the electronic components and output; Internal testing to determine the accuracy of the instrument within the specifications; More than 100% SIL2 and application of NAMU standard detection. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
