FBG Hydrostatic Level Sensor

The FBG Hydrostatic Level Sensor is a high-precision pressure monitoring system designed to measure the relative settlement of multiple points. In application, a series of FBG sensors are connected by connecting pipes. The pressure of each measuring point is measured by the sensor. Each sensor is composed of a pressure measuring fiber grating and a temperature measuring fiber grating. The sensor is composed of a sensing film to sense the change of water pressure and transmit it to the pressure grating. The sensor performs temperature compensation to correct the drift of sensor data caused by changes in external temperature.
