| Abstract: | The liquid level sensor can detect the height in the emulsion box and transmit the signal to the liquid level controller to make assure the safety operation of the emulsion pump.So high accuracy and reliability should be fit with liquid level sensor.This paper puts forward a optical fiber emulsion liquid level sensor on the basis of the evanescent field absorption of the U-shape optical fiber,introduces the sensor configuration.This light intensity-modulated optical sensor has the characteristics of the simple structure,high sensitivity,anti-electromagnetism interference and corrosion resisting,which can realize the online detection of the liquid level of the emulsion box. |
| Keywords: | emulsion box liquid level optical fiber evanescent field light intensity modulation |
