Liquid tension is measured by physical means. This type of tensiometer is widely applied in scientific research institutions, universities, and water & power sectors.

Configuration:

Structure and working principle:

The structure of the instrument mainly consists of a torsion wire, a sensor, a platinum ring and a lifting part. When in use, the platinum ring is immersed in a certain position of the liquid to be measured. Through the motor, belt and tray, the glassware containing the liquid is driven to descend. At this time, the film between the platinum ring and the liquid to be measured is stretched, causing the platinum ring to be subjected to a downward force. Through the lever arm, the torsion wire is twisted accordingly. The sensor measures the displacement at the other end of the lever arm, converts the deformation of the stretched film into a voltage, and after circuit processing, it is transformed into the corresponding tension value and automatically displayed. As the film is gradually stretched, the tension value gradually increases until the film breaks. The maximum value is recorded as the measured tension value P of the liquid. Then, multiply it by the correction factor F of the liquid to obtain the actual tension value V of the liquid, that is, V=P· F. The correction factor F depends on the measured tension value P, the density of the liquid, the radius of the platinum wire and the radius of the platinum ring.
