技术说明

034B使用三杯风速计来测量风速，风速计包含一个密封的磁性簧片开关。风杯的旋转产生与风速成正比的脉冲。由数据采集器测量脉冲频率，然后转换为工程单元（mPH，m/s，konts）。风向通过电位计测量。数据采集器为其提供激发电压，输出电压与风向成正比 。

常见问题解答

034B-QD: 1

  1. If a sensor automatically ships with a calibration sheet, what information is included on it?

    The information included on a calibration sheet differs with each sensor. For some sensors, the sheet contains coefficients necessary to program a data logger. For other sensors, the calibration sheet is a pass/fail report.
