| Abstract: | An optical fiber liquid level sensor which is constructed by two elastic corrugated pipes isintroduced in this paper. This sensor can be operated in differential manner. Especially,it is suitablefor level detecting of oil or chemical goods. The optical compensation method and several temperaturecompensation techniques were used in the transducer design, The influence of two main drawbacks(the light source fluctuation and the environment temperature variation on the sensor' s mesurementwas overcomed for this kind of structure intensity type fiber-optic sensor. |
