本文报道了一种低成本塑料光纤液位传感器的研制和试验，该传感器可用于高度易燃或其它危险环境，如油管或油箱。该传感器由一个垂直的纤维，刻槽，这将依次满足当液体上升，从而增加了传输的光功率。每个测量点获得的透射光功率强度的变化为2.60%。此外，传感器灵敏度和分辨率可以根据应用进行定制。(C)2015爱思唯尔有限公司版权所有。
This work reports de development and testing of a low cost plastic optical fiber liquid level sensor for operation within highly flammable or other hazardous environments, such in oil piping or fuel tanks. The sensor consists on a vertical fiber, with engraved grooves, that will be sequentially fulfill when the liquid rises, resulting in an increase of the transmitted optical power. A variation of 2.60% in the transmitted optical power intensity was obtained per measured point. Moreover, the sensor sensitivity and resolution can be tailored accordingly to the application.
