| Abstract: | A novel fiber optics Fabry-Perot cavity level meter is introduced in this paper, which can be applied in some inflammable and explosive circumstance. The principle and the configuration parameters designment of the sensor are given in detail. After the system error is analysed, stability issue and future improvements of the sensor are discussed. Experiment results show that the sensor is in convenient use and precise in level detecting, that indicates such sensor has a widely practical application. |
