Abstract
A micro change in level using plastic optical fiber sensor is demonstrated in this article. This sensor operates on light intensity modulation and such modulation results due to displacement of the reflector floating on the liquid. The sensor has 0.0073 V/μm sensitivity. The performance of the sensor is being tested for 950 μm change in level and shows linear increment of output voltage..
