一种自动校准多风表的风洞检测试验装置

A wind tunnel test device for automatic calibration of multiple wind meters

针对传统风表校准方式需多次手动调节风量、操作复杂、人工读数与绘图费时费力且校准精度低等问题,设计了一种自动校准多风表的风洞检测试验装置,介绍了该装置的结构及检测试验原理。试验结果表明,该装置风流稳定,可自动调节风量,操作简单,可1次校准多个风表,校准精度高,并能对校准结果进行记录、存储、处理,适合于低、中、高3档多风表自动校准。

For problems of manual adjustment of wind volume many times, complex operation, large time and laborious consumption of manual data reading and drawing and low calibration precision existed in traditional calibration methods of wind meter, a wind tunnel test device for automatic calibration of multiple wind meters was designed and structure and test principle of the device were introduced. The test result shows that the device can automatically adjust wind volume with steady wind by simple operation, calibrate multiple wind meters at a time with high calibration precision, and record, store and process calibration results, which is suitable for automatic calibration of low, medium and high grade wind meters.
