基于流变应力恢复地应力测量方法,研制了一种单线圈电流型振弦式三向压力传感器。通过单向加载标定试验和三向加载标定试验,研究了传感器的重复性、线性度及压力传感面之间的自干扰特性。
Based on the method of stress measurement of flow stress recovery, a three-direction pressure transducer with single-coil current is developed. Through one-way load calibration test and three-way load calibration test, the repeatability, linearity and self-interference characteristics of the pressure sensing surface were studied.
