Research on the Calibration Method of SWY-Ⅱ Water Level Sensor

提出一种水位传感器准确度的实验室校准方法,并结合地震台站的实际观测情况,对实验室校准方法进行改进,提出一种地震台站现场水位传感器的校准方法。通过地震台站现场校准方法的提出,从原理上基本解决了由于现场环境因素、压敏元件的非线性因素给水位观测带来的系统误差。

In this paper, a laboratory calibration method is proposed for water level sensor accuracy calibra- tion and improved according to the situation of seismic station, on this basis, a water level sensor calibra- tion method is provided for onsite calibration at seismic station. The new water level sensor calibration method can solved the systemic error caused by the environmental factors and the components of pressure sensitive nonlinear factors.
