FBG Pressure Sensor PT-01 is used for accurate measurement of fluid pressure such as liquid and gas, it is based on an industrial-grade design and uses a unique pressure elastic element as a sensing substrate, the sensor has built-in temperature compensation FBG, so as to eliminating the environment temperature influence, and get the accurate pressure measurement.
The PT-01 is embedded in hydraulic structures, bedrock or installed in piezometric pipes, boreholes, dams, pipes and pressure vessels to measure water pressure of pores or liquid level, it can also be used for dam seepage and seepage pressure monitoring, pressure vessel measurement, oil, water, gas pressure measurement, water level monitoring.
