Fiber Grating Water Pressure Sensor and System for Mine
矿井下用光纤光栅水压传感器及系统

A new water pressure sensor based fiber Bragg grating was fabricated.The sensitivity of the pressure sensor was calculated with ANSYS.The sensor was installed in coalmine to monitor the water pressure remotely and compared with manometer.It validated the feasibility of the sensor in the coalmine water pressure monitoring.
