ＳＷＹ—１型钻孔水位观测系统本系统是由兖州矿务局鲍店煤矿在山东矿业学院协助下研制的。系统由压力传感器、水位测量仪和微机等组成。压力传感器将地下水的水压转换成电频率信号，由防水钢丝电缆传送到水位测量仪。由于地下水的压力与深度成正比，所以压力传感器传出的...
SWY-1 Borehole Water Level Observation System The system was developed by the Yancheng Mining Bureau BaoDian Coal Mine with the assistance of Shandong Mining Institute. System consists of pressure sensors, water level measuring instrument and computer components. The pressure sensor converts the water pressure of groundwater into an electrical frequency signal, which is transmitted by a waterproof wire cable to a water level gauge. As the pressure of groundwater is proportional to the depth, the pressure sensor ...
