研发背景
With the widespread application and rapid improvement of the quality of electrical steel products, the use of electrical steel magnetic measuring devices for quality control by upstream and downstream enterprises of electrical steel is becoming increasingly widespread. Professional testers are paying more attention to the confidence level of device measurement data (such as absolute measurement uncertainty, annual rate of change of instrument measurement error, etc.). In the past, we used reference samples to compare single point measurements of devices to evaluate their measurement level, which is far from sufficient and does not meet the requirementsIEC 60404-2-2008，A.3 Calibration aspectsThe requirements for device calibration in the chapter, and with the development of measurement technology, many instruments can be used to calibrate the magnetic parameters of reference samples.
In light of this, we have developedTH2200It is an instrument specifically designed for traceability calibration of electrical steel magnetic measuring devices, and can be sent to metrology departments or qualified third-party testing institutions to obtain calibration certificates. Its absolute measurement uncertainty has far exceeded the accuracy of mainstream commercial magnetic measuring devices worldwide(at least3More than twice, but not includingSSTSingle chip magnetometer and Epstein square coil, etc
Error generated by magnetometer)The system realizes the traceability of magnetic parameters to basic electromagnetic physical quantities and analyzes the magnetization process (by observing the DC component in the AC current to determine whether the AC excitation of the device is qualified). It breaks through the use of low power factor loss traceability technology and weak signal ultra-low noise amplification technology to solve the problemH-coilThe calibration problem of the magnetic measurement device in the law is difficult, and it is also equipped withThree axis flux gates are used to measure environmental magnetic fields (including geomagnetic fields and power frequency alternating magnetic fields) in order to determine the impact of the environment on magnetic measurements. It is an ideal choice for calibrating electrical steel magnetic measuring devices.
