摘　　要：介绍一种基于AT切石英晶体谐振器力-频线性关系原理研制的土层压力仪。该压力仪由三个相互垂直的压力传感器和一个温度传感器及采集器构成。测试结果表明:传感器的量程为0～1.0 MPa;非线性度小于1.0%;重复性误差小于0.05%;滞后误差小于0.1%。温度的测量精度优于0.01℃。A soil pressure meter based on the principle of force-frequency linear relationship of AT-cut quartz crystal resonator was introduced. The pressure meter consists of three perpendicular pressure sensors, a temperature sensor and an acquisition. The test results show that the sensor range is 0 - 1.0 MPa; the non-linearity is less than 1.0%, the repeatability error is less than 0.05% ; the dely error is less than 0. 1%, and the temperature measurement accuracy is better than 0.01℃.
