| Abstract: | A kind of circuit measuring system for liquid level sensor was introduced. According to characteristics of light intensity modulation, a kind of receiving circuit with LD laser and double optical routes of symmetrical compersation was designed. It can dispel the interference with non-measured factors in the external environment. Through field test,the ideal measurement result has been achieved.Proved that it can be suitable for real time liquid level measurement in dangerous environment, such as chemical industry, etc. |
