Product Alias: Fiber Bragg Grating Liquid Level Sensor, FBG Level Gauge, Liquid Detector.
Product Function: Detection and determination of liquid level positions for various liquids with temperature differences in different environments.
Principle of Fiber Bragg Grating Liquid Level Sensor:
OFSCN® capillary seamless steel tube FBG liquid level sensor is a product application of the OFSCN® string FBG temperature sensor. By using pre-installed string FBG temperature sensors as reference scales, the sensor can accurately determine the position of the liquid level for liquids at different temperatures.
Structure and System Composition of FBG Liquid Level Sensor:
OFSCN® capillary seamless steel tube FBG liquid level sensor consists of fiber connectors, all-metal stainless steel seamless pipes, and fiber bragg grating arrays (FBGs) for packaging. When combined with a fiber bragg grating demodulator, it forms a fiber bragg grating liquid level sensing system.
Deployment Method and Environmental Usage of Fiber Bragg Grating Liquid Level Sensor:
OFSCN® capillary seamless steel tube FBG liquid level sensor can be directly immersed, inserted, surface-mounted, glued, or bundled in the space where the liquid to be measured is located for temperature detection and liquid level monitoring. It can be used in various sealed tanks, pools, water bodies, troughs, and other spaces.
Measurable Media and Application Industries of Fiber Bragg Grating Liquid Level Sensor:
OFSCN® capillary seamless steel tube FBG liquid level sensor is suitable for measuring low-temperature liquid air, liquid oxygen, liquid nitrogen, liquefied natural gas, ambient temperature river and lake water flow, underground water in caves, environmental water accumulation, high-temperature liquid chemical raw materials, and some low-temperature metal liquids. It can be used in various fields such as petroleum, petrochemical, chemical, transportation, tunnels, environmental protection, aerospace, aviation, nuclear power, and high-end scientific research.
Operating Temperature and Product Details of Fiber Bragg Grating Liquid Level Sensor:
-40°C to +100°C Product: 100°C Fiber Bragg Grating Temperature Sensor - Single-point/Multipoint Bragg FBG Thermometer
-200°C to +300°C Product: 300°C Fiber Bragg Grating Temperature Sensor - Single-point/Multipoint Bragg FBG Thermometer
Advantages of Fiber Bragg Grating Liquid Level Sensor:
Compared to pressure-based FBG liquid level sensors, OFSCN® capillary seamless steel tube FBG liquid level sensor detects liquid levels based on the temperature of the liquid and the position of the FBG array. Therefore, it is widely applicable to various media without considering the density and pressure difference of different liquids.
Compared to various electric signal liquid level sensors based on capacitance and electrodes, OFSCN® capillary seamless steel tube FBG liquid level sensor is based on optical fiber communication and fiber sensing technology, making it immune to electromagnetic interference and capable of operating in various electromagnetic environments.
Compared to traditional float-type liquid level sensors, OFSCN® capillary seamless steel tube FBG liquid level sensor is a digital, recordable, and networkable sensor. Liquid level information can be obtained without visual observation. The composed fiber Bragg grating liquid level sensing system can monitor liquid level information over large spaces, long distances, and multiple targets, with a wide coverage range.
