| 摘 要： | 根据超声波检测原理，自行设计能在线检测的超声波传感器探头，研究了在线乙醇浓度超声波传感器，发现温度是影响传感器灵敏度的重要因素之一，为此选择了换能器材料P和安装了测温铂电极，有效地降低了温度对超声波信号的影响，提高了检测的灵敏度，乙醇浓度超声波传感器有效检测浓度范围在93％～100％(V／V)，检测灵敏度为0．1％(V／V)，可在线测量无水酒精或燃料酒精产品的乙醇浓度。

| Abstract: | The on - line ultrasonic sensor was designed according to the ultrasonic measurement principles. The results indicated that temperature was one of the important factors effecting sensor' sensitivity. Exchanging the transducer with the P material and assembling the temperature sensor could eliminate the influence. The range of ethanol concentration measurement was 93 to 100% (v/v), the accuracy was up to 0. l%(v/v).The ethanol concentration ultrasonic sensor could be applied for on-line detecting the ethanol concentration in fuel alcohol |
