Applications of fiber optic sensors FS-V31P
1. Temperature measurement
Fiber optic sensor FS-V31P
Fiber optic sensors can be used to measure temperature in high or low temperature environments. The advantage of this sensor is that it can measure very small temperature changes and can measure temperatures at different locations. In the industrial field, fiber optic sensors are widely used for temperature measurement. For example, in heat treatment processes, fiber optic sensors are used to monitor temperature changes in heating furnaces.
2. Pressure measurement
Fiber optic sensors can be used to measure pressure changes in different pressure ranges. The advantage of this sensor is that it can measure pressure at different locations and can measure very small pressure changes. In the industrial field, fiber optic sensors are widely used for pressure measurement. For example, in oil wells and natural gas pipelines, fiber optic sensors are used to monitor pressure changes within the pipeline.
