Research On Calibration Method Of Pressure Sensor

Pressure sensor is the most widely used in measurement of pressure, the sensor with high frequency response, high precision, good stability, small volume, easy to integrate and so on, it in biological, medical, aerospace, marine engineering, atomic and other cutting-edge technology and industry have extensive application, and its accuracy is directly related to the quality of products, quality detection. But, at present there is no national criterion of technical parameters of the pressure sensor of the professional verification regulation or calibration specification of technical indicators, evaluation and identification method can not be applied to uniform the overall performance of the pressure sensor, calibration method of pressure sensor so imperative.Firstly, this paper briefly introduces the use of pressure sensors, as well as the domestic and foreign development status, and the main research results.Secondly, this paper respectively analyzes the detection method for pressure sensor static calibration and dynamic alibration. The calibration method of pressure sensor and integrate with the existing domestic related standards, in order to ensure the accurate measurement of the pressure sensor, provide the technical means and assessment. Application of LabVIEW software to program for automatic acquisition and data processing of experimental data, Using the mature software LabVIEW, realize the fast development of software design, reduce the difficulty of software development. Fundamentally solve the currently for pressure sensor calibration using manual testing lead to problems such as low efficiency, big error.The calibration method of the pressure sensor, we establish a set of scientific and economic calibration with standard device, issued and implemented a series of measurement technology criterion in the local area, to ensure that the pressure sensor data accuracy, consistency, reliability, based on which to meet the statutory requirements, the market norms and effective supervision implementation in the third party fair and technical level provides technical references and powerful experimental data.
