Abstract
The utility model provides a device for measuring a tension coefficient of a liquid surface. At present, problems that the liquid level is hard to accurately regulate, gas flow rate is hard to control and pressure zero point is hard to determine exist in a liquid surface tension detector using a maximum bubble method; and moreover, as an experimental device is simpler and cruder, the precision and accuracy of a measuring result are affected. According to the utility model, the device comprises a base (1), wherein the base is connected with a tray (3) through a supporting column; a liquid container (4) is mounted on the tray; an annular lifting sheet (5) is mounted above the liquid container; the annular lifting sheet is connected with a cross beam (7) in which a force sensor (6) is mounted; the cross beam is mounted on a bracket (8); a lifting adjusting mechanism (2) is mounted on the bracket; the bracket is fixedly mounted on the base; and the force sensor is connected with a liquid surface tension coefficient detector (9). The device for measuring the tension coefficient of the liquid surface, provided by the utility model, is used for measuring the tension coefficient of the liquid surface.
