Infrared thermometer in the inspection system application
Detection system this function is the infrared thermometer technology development to a certain stage of the product. Detection system is an organic combination of pyrometer and measuring instruments, conversion devices and so on.
The error is the difference between the measured value and the true value, which reflects the accuracy of the measurement.
With the development of science and technology, people are demanding more and more measurement accuracy, and it can be said that the value of the measurement work depends on the accuracy of the measurement. When the measurement error exceeds a certain limit, the measurement work and the measurement results lose their significance and even bring harm to the work. Therefore, the analysis and control of measurement error has become an important aspect to measure the level of measurement technology and even the level of science and technology. However, due to the inevitability and universality of the existence of the error, people can only control the error in the smallest possible range, but can not completely eliminate it.
On the other hand, the reliability of the measurement is also crucial, different occasions, different systems on the reliability of the measurement results of different requirements. For example, when the measured value is used as a control signal, attention should be paid to the stability and reliability of the measurement. Therefore, the accuracy and reliability of the measurement and other performance indicators must be linked to the purpose and requirements of the specific measurement, adaptable. So that the function of infrared thermometer as well as the characteristics of the better play out!
In engineering practice, it is necessary to have a pyrometer and multiple measuring instruments organically combined to form a whole, in order to complete the detection of electrical signals, so that the formation of the detection system. With the continuous development of computer technology and information processing technology, the detection system involved in the content has been enriched. In the modern production process, the detection of process parameters are automatic, that is, the detection task is completed automatically by the detection system, so it is necessary to study and master the composition and principle of the detection system.
The purpose of measurement is to obtain the true value of the measured by measurement. However, in the actual measurement process, due to various reasons, for example, the performance of the pyrometer itself is not ideal, the measurement method is not perfect, the influence of external interference and human negligence, etc., will cause the measured value of the measured parameter and the real value is inconsistent, the degree of inconsistency between the two is expressed by the measurement error.
The infrared thermometer in the system is a device or apparatus that measures the size of the measured object and outputs a corresponding usable output signal. The data transmission link is used to transmit the data. When the detection system of several functional links independently separated from each other, it is necessary to transmit data from one place to another, the data transmission link is to complete this transmission function.
From the infrared thermometer product itself, infrared thermometer is a mature product. With the development of technology in recent years, on the one hand, the infrared thermometer products are intelligent, increased self-diagnosis and self-calibration and other functions. Thus, to achieve some online self-diagnostic functions, reduce the maintenance workload of the equipment, by the online inspection instead of the traditional offline inspection methods. Infrared thermometer online inspection methods from the birth of the application is becoming increasingly mature, but to promote in various industries still need some time. Its * big difficulty lies in the infrared thermometer as an instrument, its online inspection specifications need to get the national technical supervision departments and the relevant industry associations on the recognition.
Data processing link is the output signal of the thermometer for processing and transformation. Such as signal amplification, arithmetic, filtering, linearisation, digital-analogue (D / A) or analogue-to-digital (D / A) conversion, converted into another parameter signal or a standardised uniform signal, etc., so that the output signal is easy to display, record, but also with the computer system connected to the measurement signal for information processing or for the automatic control of the system. Data display link will be measured information into a form acceptable to the senses, in order to achieve the purpose of monitoring, control or analysis. Measurement results can be displayed in analogue or digital form, and can be recorded automatically by a recording device or printed out by a printer.
