Hanvy - Model FBG -Temperature and Humidity Sensoring System
Fiber Bragg Grating Temperature and Humidity Sensor is an advanced fiber optic sensor based on conventional humidity sensitivity principles and advanced fiber optic measurement methods. The humidity sensitive element inside the sensor expands or contracts with the increase or decrease of the environmental humidity. The strain change of the humidity sensitive material is transferred to the strain sensitive grating through the sensitizing structure. Environmental humidity information.
- The probe is passive and can work in a flammable and explosive environment;
- Multiplexed measurement of multiple probes can be realized;
- Simultaneous measurement of humidity and temperature;
- The probe is stable and has a long working life;
- Humidity measurement range: 12% ~ 98% RH;
- Humidity measurement accuracy: ± 3% RH;
- Temperature measurement range: -20 ℃ ~ 50 ℃;
- Temperature measurement accuracy: ± 0.5 ℃.
Optical fiber humidity sensors are mainly used for the measurement of environmental humidity and temperature in flammable and explosive environments, such as passive temperature and humidity monitoring in tobacco warehouses, and passive temperature and humidity monitoring in military explosives storage environments.It can detect up to 62 miles. Scope of application: petroleum pipelines, oil and gas pipelines, buildings, petroleum storage tanks, subway tunnels, coal belt conveyors, smart pipe corridors, warehouses, bridges, power cables, natural gas stations, borders, PCCP pipelines, high-speed rail tunnels, ancient buildings, geological surveys , Highways, oil production stations, geothermal exploration, thermal energy storage tanks, oil wells, etc.
