Abstract: PROBLEM TO BE SOLVED: To provide a novel methanol concentration sensor that is less likely to be affected by electrical noise, the temperature of the solution, or the convection of methanol. SOLUTION: An electrode pair consisting of a first electrode 17a and a second electrode 17b and an insulating part 17c fitted between the electrode pair to insulate it are provided on a first partition plate 7. A wiring 16a and a wiring 16b are provided at an outer wall of a sensor 2 in connection with the first electrode 17a and the second electrode 17b, respectively. When a methanol concentration is appropriate, a float 3 is in a contact state with the first electrode 17a and the second electrode 17b, and the wiring 16a is in a conductive state with the wiring 16b. With this, a range of concentration is sensed to be appropriate. If the concentration lowers, the float 3 floats and conduction between the pair electrodes is cut off, and a concentration abnormality is detected. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a liquid fuel concentration sensor or the like having a simple structure and high measuring precision. SOLUTION: Since a polymer film 665, which has a property increased in its swelling ratio with an increase in the concentration of the alcohol in fuel, constituting a sensor 668 is used, if the concentration of the alcohol in the fuel is increased, the number density of the conductive fillers 1,688 in a composite membrane 1,686 is reduced with the increase in the concentration of the alcohol in the fuel. Since the number of electrical contact points between the respective conductive fillers 1,688 present in the composite membrane 1,686 is reduced, the electric resistance value of the composite membrane 1,686 is increased when a current is allowed to flow to the composite membrane 1,686. Accordingly, the concentration of the alcohol in the fuel can be measured by measuring the electric resistance value using first and second electrode terminals 666 and 667 to monitor a change in the electric resistance value of the composite membrane 1,686.

Abstract translation: 要解决的问题：提供一种结构简单，测量精度高的液体燃料浓度传感器等。 解决方案：如果燃料中的醇的浓度增加，则使用构成传感器668的具有随着燃料中醇的浓度增加而具有膨胀率增加的性质的聚合物膜665 复合膜1,686中的导电填料1,688的数量密度随着燃料中醇浓度的增加而降低。 由于存在于复合膜1,686中的各个导电填料1,688之间的电接触点的数量减少，所以当允许电流流到复合膜1,686时复合膜1,686的电阻值增加。 因此，可以通过使用第一和第二电极端子666和667测量电阻值来测量燃料中的醇的浓度，以监测复合膜1,686的电阻值的变化。 版权所有（C）2006，JPO＆NCIPI
